<em>New York Times</em> Hacked Again, This Time Allegedly by Chinese



In a dramatic announcement late Wednesday, the New York Times reported that hackers from China had been routing through the paper’s network for at least four months, stealing the passwords of reporters in an apparent attempt to identify sources and gather other intelligence about stories related to the family of China’s prime minister.


The hackers breached the network sometime around Sept. 13 and stole the corporate passwords for every Times employee, using them to gain access to the personal computers of 53 employees, according to the report.


The hacking coincided with an investigation the Times published last October that looked into a fortune that the family of China’s Prime Minister Wen Jiabao had amassed. The hackers breached the network while the paper was in the process of concluding its reporting for the investigation.


The hackers broke into the email account of the newspaper’s Shanghai bureau chief, David Barboza, who conducted the investigation, as well as the email account of Jim Yardley, the paper’s South Asia bureau chief in India, who had previously worked out of Beijing.


Executive Editor Jill Abramson said, however, that forensic experts with Mandiant, the computer security firm hired to investigate the breach, found “no evidence that sensitive e-mails or files from the reporting of our articles about the Wen family were accessed, downloaded or copied.”


It’s not the first time that the paper has been hacked. In 1998, a group known as HFG — or H4acking for Girl13z — hacked the paper’s web site to protest the arrest of hacker Kevin Mitnick and accuse Times reporter John Markoff of helping to catch him.


In 2002, former hacker Adrian Lamo, famously hacked the paper’s network after discovering multiple vulnerabilities and accessed a database containing the details of 3,000 contributors to the paper’s op-ed page, among other things.


In 2011, former executive editor of the Times, Bill Keller, hinted that WikiLeaks or someone associated with the group had hacked into the accounts of some of the paper’s staff. During a period of heightened tension between WikiLeaks founder Julian Assange and the paper, which was then a publishing partner of WikiLeaks, the e-mail accounts of at least three people at the Times were apparently hacked. Keller suggested that Assange and WikiLeaks were behind the intrusions but never offered evidence to support this.


In the latest hack, the attackers, in an attempt to hide their tracks, routed their attacks through computers that they hacked at universities in North Carolina, Arizona, Wisconsin and New Mexico, as well as at small companies and internet service providers. They apparently used the same university computers that hackers working for the Chinese military used previously to attack Defense Department contractors.


During the three months they were in the paper’s network, the attackers installed 45 pieces of custom malware, though nearly all of it went undetected. Although the newspaper uses antivirus products made by Symantec, the monitoring software identified and quarantined only one of the attacker’s tools during that time, according to the report.


The attackers increased their activity in late October after the paper published its investigation of the prime minister’s relatives, and were also particularly active the night of the Nov. 6 presidential election.


The paper noted that there were concerns the hackers would try to shut down its publishing system that night, but they turned out to be unwarranted since the attackers apparently showed interest only in the paper’s reporting about the prime minister’s family.


“They could have wreaked havoc on our systems,” said Marc Frons, the Times’s chief information officer said in the report. “But that was not what they were after.”


The Times had been on alert for suspicious activity after learning that Chinese officials had warned that the paper’s reporting would have consequences. The paper asked AT&T, which monitors its network, to be on the lookout for suspicious activity.


After AT&T reported finding such activity, the FBI was notified, and the Times called in Mandiant to investigate.


Evidence showed that the hackers installed three backdoors and routed their way through the network for two weeks before uncovering a system containing the computer usernames and hashed passwords for all of the paper’s employees. The hackers apparently cracked a number of passwords to gain entry to employee computers.


“They created custom software that allowed them to search for and grab Mr. Barboza’s and Mr. Yardley’s e-mails and documents from a Times e-mail server,” the paper revealed.


The intrusion is apparently part of a wider campaign directed by Chinese hackers against western media outlets since 2008. Hackers from China also attempted to hack into the network of Bloomberg News last year after publishing stories about the relatives of China’s vice president.


Mandiant has investigated many of the breaches and found evidence that Chinese hackers had stolen e-mails, contact lists and files from more than 30 journalists and executives working for western media outlets.

“Sin City 2″ casts Eva Green and Julia Garner






LOS ANGELES (TheWrap.com) – “Sin City: A Dame to Kill For” has cast Eva Green as a femme fatale and Julia Garner to portray yet another stripper struggling to make a dime in the gritty comic-book metropolis.


Green (“Casino Royale”) will appear in the sequel to the 2005 hit, “Sin City,” as a deadly muse named Ava Lord. Garner (“The Perks of Being a Wallflower”) plays a stripper who appears in scenes with Johnny, a cocky young gambler played by Joseph Gordon-Levitt.






Like the first film, “A Dame to Kill For” is adapted from Frank Miller‘s graphic novels.


Miller, who is co-directing with Robert Rodriguez, says Green’s character is “every man’s most glorious dreams come true, she’s also every man’s darkest nightmares.”


Ava Lord is one of the most deadly and fascinating residents of ‘Sin City.’ From the start, we knew that the actor would need to be able to embody the multifaceted characteristics of this femme fatale and we found that in Eva Green,” Miller and Rodriguez added in a statement. “We are ecstatic that Eva is joining us.”


Green and Garner are newcomers to the sequel, along with Gordon-Levitt, Jaime King, Josh Brolin, Dennis Haysbert, Michael Madsen, Christopher Meloni, Jeremy Piven, Ray Liotta, Juno Temple and Jamie Chung.


Returning from the first “Sin City” are Mickey Rourke, Jessica Alba, Bruce Willis and Rosario Dawson.


The sequel is currently filming at Rodriguez’s Troublemaker Studios in Austin, Texas and is scheduled for an October 4 theatrical release.

Well: Waiting for Alzheimer's to Begin

My gray matter might be waning. Then again, it might not be. But I swear that I can feel memories — as I’m making them — slide off a neuron and into a tangle of plaque. I steel myself for those moments to come when I won’t remember what just went into my head.

I’m not losing track of my car keys, which is pretty standard in aging minds. Nor have I ever forgotten to turn off the oven after use, common in menopausal women. I can always find my car in the parking lot, although lots of “normal” folk can’t.

Rather, I suddenly can’t remember the name of someone with whom I’ve worked for years. I cover by saying “sir” or “madam” like the Southerner I am, even though I live in Vermont and grown people here don’t use such terms. Better to think I’m quirky than losing my faculties. Sometimes I’ll send myself an e-mail to-do reminder and then, seconds later, find myself thrilled to see a new entry pop into my inbox. Oops, it’s from me. Worse yet, a massage therapist kicked me out of her practice for missing three appointments. I didn’t recall making any of them. There must another Nancy.

Am I losing track of me?

Equally worrisome are the memories increasingly coming to the fore. Magically, these random recollections manage to circumnavigate my imagined build-up of beta-amyloid en route to delivering vivid images of my father’s first steps down his path of forgetting. He was the same age I am now, which is 46.

“How old are you?” I recall him asking me back then. Some years later, he began calling me every Dec. 28 to say, “Happy birthday,” instead of on the correct date, Dec. 27. The 28th had been his grandmother’s birthday.

The chasms were small at first. Explainable. Dismissible. When he crossed the street without looking both ways, we chalked it up to his well-cultivated, absent-minded professor persona. But the chasms grew into sinkholes, and eventually quicksand. When we took him to get new pants one day, he kept trying on the same ones he wore to the store.

“I like these slacks,” he’d say, over and over again, as he repeatedly pulled his pair up and down.

My dad died of Alzheimer’s last April at age 73 — the same age at which his father succumbed to the same disease. My dad ended up choosing neurology as his profession after witnessing the very beginning of his own dad’s forgetting.

Decades later, grandfather’s atrophied brain found its way into a jar on my father’s office desk. Was it meant to be an ever-present reminder of Alzheimer’s effect? Or was it a crystal ball sent to warn of genetic fate? My father the doctor never said, nor did he ever mention, that it was his father’s gray matter floating in that pool of formaldehyde.

Using the jarred brain as a teaching tool, my dad showed my 8-year-old self the difference between frontal and temporal lobes. He also pointed out how brains with Alzheimer’s disease become smaller, and how wide grooves develop in the cerebral cortex. But only after his death — and my mother’s confession about whose brain occupied that jar — did I figure out that my father was quite literally demonstrating how this disease runs through our heads.

Has my forgetting begun?

I called my dad’s neurologist. To find out if I was in the earliest stages of Alzheimer’s, he would have to look for proteins in my blood or spinal fluid and employ expensive neuroimaging tests. If he found any indication of onset, the only option would be experimental trials.

But documented confirmation of a diseased brain would break my still hopeful heart. I’d walk around with the scarlet letter “A” etched on the inside of my forehead — obstructing how I view every situation instead of the intermittent clouding I currently experience.

“You’re still grieving your father,” the doctor said at the end of our call. “Sadness and depression affect the memory, too. Let’s wait and see.”

It certainly didn’t help matters that two people at my father’s funeral made some insensitive remarks.

“Nancy, you must be scared to death.”

“Is it hard knowing the same thing probably will happen to you?”

Maybe the real question is what to do when the forgetting begins. My dad started taking 70 supplements a day in hopes of saving his mind. He begged me to kill him if he wound up like his father. He retired from his practice and spent all day in a chair doing puzzles. He stopped making new memories in an all-out effort to preserve the ones he already had.

Maybe his approach wasn’t the answer.

Just before his death — his brain a fraction of its former self — my father managed to offer up a final lesson. I was visiting him in the memory-care center when he got a strange look on his face. I figured it was gas. But then his eyes lit up and a big grin overtook him, and he looked right at me and said, “Funny how things turn out.”

An unforgettable moment?

I can only hope.



Nancy Stearns Bercaw is a writer in Vermont. Her book, “Brain in a Jar: A Daughter’s Journey Through Her Father’s Memory,” will be published in April 2013 by Broadstone.

Chinese Hackers Infiltrate New York Times Computers





SAN FRANCISCO — For the last four months, Chinese hackers have persistently attacked The New York Times, infiltrating its computer systems and getting passwords for its reporters and other employees.







The New York Times published an article in October about the wealth of the family of China's prime minister, Wen Jiabao, in both English and Chinese.







After surreptitiously tracking the intruders to study their movements and help erect better defenses to block them, The Times and computer security experts have expelled the attackers and kept them from breaking back in.


The timing of the attacks coincided with the reporting for a Times investigation, published online on Oct. 25, that found that the relatives of Wen Jiabao, China’s prime minister, had accumulated a fortune worth several billion dollars through business dealings.


Security experts hired by The Times to detect and block the computer attacks gathered digital evidence that Chinese hackers, using methods that some consultants have associated with the Chinese military in the past, breached The Times’s network. They broke into the e-mail accounts of its Shanghai bureau chief, David Barboza, who wrote the reports on Mr. Wen’s relatives, and Jim Yardley, The Times’s South Asia bureau chief in India, who previously worked as bureau chief in Beijing.


“Computer security experts found no evidence that sensitive e-mails or files from the reporting of our articles about the Wen family were accessed, downloaded or copied,” said Jill Abramson, executive editor of The Times.


The hackers tried to cloak the source of the attacks on The Times by first penetrating computers at United States universities and routing the attacks through them, said computer security experts at Mandiant, the company hired by The Times. This matches the subterfuge used in many other attacks that Mandiant has tracked to China.


The attackers first installed malware — malicious software — that enabled them to gain entry to any computer on The Times’s network. The malware was identified by computer security experts as a specific strain associated with computer attacks originating in China. More evidence of the source, experts said, is that the attacks started from the same university computers used by the Chinese military to attack United States military contractors in the past.


Security experts found evidence that the hackers stole the corporate passwords for every Times employee and used those to gain access to the personal computers of 53 employees, most of them outside The Times’s newsroom. Experts found no evidence that the intruders used the passwords to seek information that was not related to the reporting on the Wen family.


No customer data was stolen from The Times, security experts said.


Asked about evidence that indicated the hacking originated in China, and possibly with the military, China’s Ministry of National Defense said, “Chinese laws prohibit any action including hacking that damages Internet security.” It added that “to accuse the Chinese military of launching cyberattacks without solid proof is unprofessional and baseless.”


The attacks appear to be part of a broader computer espionage campaign against American news media companies that have reported on Chinese leaders and corporations.


Last year, Bloomberg News was targeted by Chinese hackers, and some employees’ computers were infected, according to a person with knowledge of the company’s internal investigation, after Bloomberg published an article on June 29 about the wealth accumulated by relatives of Xi Jinping, China’s vice president at the time. Mr. Xi became general secretary of the Communist Party in November and is expected to become president in March. Ty Trippet, a spokesman for Bloomberg, confirmed that hackers had made attempts but said that “no computer systems or computers were compromised.”


Signs of a Campaign


The mounting number of attacks that have been traced back to China suggest that hackers there are behind a far-reaching spying campaign aimed at an expanding set of targets including corporations, government agencies, activist groups and media organizations inside the United States. The intelligence-gathering campaign, foreign policy experts and computer security researchers say, is as much about trying to control China’s public image, domestically and abroad, as it is about stealing trade secrets.

An earlier version of this article misstated the year that the United States and Israel were said to have started a cyber attack that caused damage at Iran’s main nuclear enrichment plant, and the article misstated the specific type of attack. The attack was a computer worm, not a virus, and it started around 2008, not 2012.

South Korea launches space rocket carrying satellite









South Korea said Wednesday it successfully launched a satellite into space from its own soil for the first time, a point of national pride that came weeks after archrival North Korea accomplished a similar feat to the surprise of the world.


The South Korean rocket blasted off from a launch pad in the southwestern coastal village of Goheung. Science officials told cheering spectators minutes later that the rocket delivered an observational satellite into orbit. There was no immediate confirmation that the satellite was operating as intended.


The launch is a culmination of years of efforts by South Korea — Asia's fourth-largest economy — to advance its space program and cement its standing as a technology powerhouse whose semiconductors, smartphones and automobiles command global demand. North Korea's long-range rocket program, in contrast, has generated international fears that it is getting closer to developing nuclear missiles capable of striking the U.S.





South Korea's success comes amid increased tension on the Korean Peninsula over North Korea's threat to explode its third nuclear device. Pyongyang is angry over tough new international sanctions over its Dec. 12 rocket launch and has accused its rivals of applying double standards toward the two Koreas' space programs.


Washington and Seoul have called North Korea's rocket launch a cover for a test of Pyongyang's banned ballistic missile technology.


Both Koreas see the development of space programs as crucial hallmarks of their scientific prowess and national pride, and both had high-profile failures before success. South Korea tried and failed to launch satellites in 2009 and 2010, and more recent launch attempts were aborted at the last minute.


The satellite launched by Seoul is designed to analyze weather data, measure radiation in space, gauges distances on earth and test how effectively South Korean-made devices installed on the satellite operate in space. South Korean officials said it will help them develop more sophisticated satellites in the future.


U.S. experts have described the North's satellite as tumbling in space and said it does not appear to be functioning, though Pyongyang has said it is working.


The South Korean rocket launched Wednesday had its first stage designed and built by Russian experts under a contract between the two governments. North Korea built its rocket almost entirely on its own, South Korean military experts said earlier this month after analyzing debris retrieved from the Yellow Sea in December.

Actor Jason London arrested after Ariz. bar fight






PHOENIX (AP) — Authorities say actor Jason London has been arrested on suspicion of assault and disorderly conduct after an Arizona bar fight.


Scottsdale police say London allegedly sneezed on a man who then asked him to apologize, but London refused and instead hit the man in the face.






The Arizona Republic (http://bit.ly/VoULau ) says the two men were escorted out of the bar, but London began pushing and cursing at firefighters trying to treat him and appeared extremely drunk. He was arrested early Monday.


London’s Twitter account says “some guy thought I was hitting on his girl” and that several large bouncers beat him, breaking bones in his face. London added, “the truth will win” and “I hate Arizona.”


London is best known for the 1993 movie “Dazed and Confused.”

BlackBerry 10’s Debut Is a Critical Day for Research in Motion





OTTAWA — Research in Motion’s introduction on Wednesday of a new BlackBerry phone will be the most important event in the company’s history since 1996, when its founders showed investors a small block of wood and promised that a wireless e-mail device shaped like that would change business forever.




Now with just 4.6 percent of the global market for smartphones in 2012, according to IDC, RIM long ago exchanged dominance for survival mode. On Wednesday, the company will introduce a new line of smartphones called the BlackBerry 10 and an operating system of the same name that Thorsten Heins, the president and chief executive of RIM, says will restore the company to glory.


But Frank Mersch, who became one of RIM’s earliest investors after seeing the block of wood, is far less excited by what he sees this time around.


“You’re in a very, very competitive market and you’re not the leader,” Mr. Mersch, now the chairman and a vice president at Front Street Capital in Toronto, said of RIM. “You have to ask: ‘At the end of the day are we really going to win?’ I personally think the jury’s out on that.”


The main elements of the new phones and their operating system are already well known. Mr. Heins and other executives at RIM have been demonstrating the units for months to a variety of audiences. App developers received prototype versions as far back as last spring.


While analysts and app developers may be divided about the future of RIM, there is a consensus that BlackBerry 10, which arrives more than year behind schedule, was worth the wait.


Initially RIM will release two variations of the BlackBerry 10, one a touch-screen model that resembles many other phones now on the market. The other model is a hybrid with a keyboard similar to those now found on current BlackBerrys as well as a small touch screen.


The real revolution, though, may be in the software that manages a person’s business and personal information. It is clearly designed with an eye toward retaining and, more important, luring back, corporate users.


Corporate and government information technology managers will be able to segregate business-related apps and data on BlackBerry 10 handsets from users’ personal material through a system known as BlackBerry Balance. It will enable an I.T. manager to, among other things, remotely wipe corporate data from fired employees’ phones while leaving the newly jobless workers’ personal photos, e-mails, music and apps untouched. The system can also block users from forwarding or copying information from the work side of the phone.


Messages generated by e-mail, Twitter, Facebook, instant messaging and LinkedIn accounts are automatically consolidated into a single in-box that RIM calls BlackBerry Hub.


Charles Golvin, an analyst with Forrester Research, called the new phones “beautiful” and described the operating system as “a giant leap forward” from RIM’s current operating system. Ray Sharma, who followed RIM’s glory years as a financial analyst but who now runs XMG Studio, a mobile games developer in Toronto, has been similarly impressed.


But both men are among many analysts who question the ability of BlackBerry 10, whatever its merits, to revive RIM’s fallen fortunes.


“If it’s good, it will help inspire the upgrade cycle,” Mr. Sharma said. “But it has to be great in order to inspire touch-screen users to come back. If it’s good, not great, I will be concerned.”


Mr. Golvin was more blunt. “They’ll need to prove themselves in the face of a simultaneous onslaught of marketing from Microsoft, not to mention the continued push from Apple plus Google and its Android partners,” he wrote. “This is a gargantuan challenge for a company of RIM’s size.”


In the year since he took over from the founders, Jim Balsillie and Mike Lazaridis, Mr. Heins has certainly remade RIM. He cut 5,000 jobs in a program to reduce operating costs by about $1 billion a year. Along the way, he also replaced RIM’s senior management and straightened out its balance sheet. While unprofitable, RIM remains debt-free and holds $2.9 billion in cash.


With BlackBerry 10, RIM not only started over with its operating system, it also rebuilt the company through acquisitions. Its core operating system comes from QNX Software Systems, the design of the user interface is largely the work of the Astonishing Tribe in Sweden while other main components, like the touch-screen technology, came from smaller companies that are now part of RIM.


Integrating all of those acquisitions, analysts and former RIM employees say, added to the delays that plagued BlackBerry 10.


Now that the new phones are finally here, Mr. Heins is counting on RIM’s remaining base of 79 million users globally to eagerly upgrade. But where those customers reside may be as important in their numbers in determining the success of that plan.


In the United States, which leads the world in setting smartphone trends, about 11 million BlackBerry users switched to other phones between 2009 and the middle of last year, according to an analysis by Horace Dediu on Asymco, a wireless industry blog he founded.


Until the final months of 2012, RIM continued to increase its subscriber base through sales of low-cost handsets to less developed countries like Nigeria and Indonesia. Although BlackBerry 10 will be made available worldwide, the initial phones will be too expensive for a majority of BlackBerry fans in those regions.


RIM may also have confused its loyalists, particularly in North America and Europe, in the run-up to the BlackBerry 10 debut. Many of those users stuck with BlackBerrys because of their physical keyboards. But public demonstrations for BlackBerry 10 were centered on the touch-screen-only version and its virtual keyboard.


While some corporations have remained loyal to BlackBerry, RIM not only has to sell them on the new handsets, it also must persuade them to upgrade server software to accommodate the new operating system, a costly and time-consuming process. Companies whose employees continue to use older BlackBerrys will have to run two separate BlackBerry servers.


Mr. Heins’s pitch to those corporations is that the BlackBerry 10 server software will also allow them to manage and control data on employees’ Android phones and iPhones. But any corporation or organization that allows those phones to connect with its systems long ago installed mobile device management software from other companies, including Good Technology and SAP. RIM is likely to find that the competition in device management software is as severe as it is in the handset business.

Mayoral debate focuses on city's troubled finances









In the highest-profile debate so far in the Los Angeles mayoral race, three longtime city officials defended their records Monday night as two long-shot challengers accused them of putting the city on a path to insolvency.


The city's chronic budget shortfalls dominated the event at UCLA's Royce Hall, televised live on KNBC-TV Channel 4. Entertainment lawyer Kevin James and technology executive Emanuel Pleitez sought to maximize the free media exposure, portraying themselves as fresh alternatives to business as usual at City Hall.


James, a former radio talk-show host, described himself as an independent and accused rivals Wendy Greuel, Eric Garcetti and Jan Perry — all veteran elected officials — of being cozy with unions representing the city workforce.





"Bankruptcy doesn't happen overnight," said James, the only Republican in the race. "This happened over a period of time and it happened because of a series of bad decisions."


Pleitez struck a similar note.


"Our politicians in the last decade made decisions on numbers they didn't understand," he said.


"I'm the only one that has worked in the private sector and on fiscal and economic policies at the highest levels," Pleitez said, citing his experience as a special assistant to economist Paul Volcker on President Obama's Economic Recovery Advisory Board.


Greuel, Garcetti and Perry, in turn, pledged to show fiscal restraint as the city grapples with projected budget shortfalls totaling more than $1 billion over the next four years.


City Controller Greuel cited the "waste, fraud and abuse" her office's audits have identified at City Hall, saying they demonstrate her independence.


"As mayor of Los Angeles, I get not only being the fiscal watchdog, and showing where we can find this money, and knowing where the bodies are buried," said Greuel, who served on the City Council for seven years. "I've learned as city controller, you don't always make friends when you highlight what can be done better."


Garcetti, a councilman for more than a decade, said he had a record of "not just talking about pension reform, but delivering on it." When tax collections dried up in the recession, he said, the council and mayor eliminated 5,000 jobs and negotiated a deal with unions requiring some city workers to contribute to their health and pension benefits.


"Those are the things that kept us away from our own fiscal cliff," he said.


Perry also stressed her support for increasing worker contributions to health and retirement benefits.


"This is about long-term survival," she said.


By the normal standards of election campaigns, it was a remarkably genteel debate, at least among the three city officials.


Only Perry attacked her rivals, and even then, not by name.


Recalling her work with Garcetti and Greuel in talks with city unions, she faulted them for engaging in "side meetings and side negotiations," saying she was more transparent.


"As mayor, I will make sure that practice stops, that everything is done on the record — that all employees are treated fairly and all employees are given the same information," Perry said.


Neither Greuel nor Garcetti answered the attack.


As in previous forums, the most obvious contrasts among the candidates Monday night were in biography and style — rather than policy positions.

Supernova Remnants: Dazzling Entrails of Violent Stellar Death

Even in death, there can be great beauty. Consider supernova remnants, the results of massive stars dying in great explosions, creating some of the most spectacular cosmic objects around.


Every 50 years or so, a star in our galaxy with more than 10 times the mass of our sun will expire. When such stars die, they go supernova, one of the most violent events in our universe. These explosions shoot off tons of material from the central star at up to 10 percent the speed of light.


Though the area surrounding stars seems empty, it is usually home to vast amounts of interstellar gas and dust. The supernova’s outburst runs into this surrounding material, creating a shockwave and heating it to temperatures greater than 10,000 Celsius. Over thousands of years, the local structure of the gas and dust shapes the stellar outpouring into shells, filaments, and other diffuse forms. Astronomers call these objects supernova remnants.


Supernova explosions and the remnants they leave behind have wide-ranging effects. They heat up the interstellar medium, creating complex chemistry out in space, and are responsible for accelerating protons and other atomic nuclei, which go zipping around the universe as cosmic rays. Perhaps most importantly, supernova explosions generate and liberate heavy elements, such as oxygen, carbon, and all metals, distributing them out into the wider cosmos. These elements eventually find their way into planetary systems, making life possible on at least one world that we know of.


Here, we take a look at some of the most famous and beautiful supernova remnants, giving you a chance to contemplate life, death, and cycles of renewal in the universe.


Above:



The supernova remnant N186 D appears as a bright pink spot at the top of this new image released by NASA on Jan. 28, spewing off tremendous amounts of X-rays. Located in the Large Magellanic Cloud about 160,000 light-years away, the remnant is blowing a huge bubble (the giant structure below the bright spot) as hot wind carves out a shock wave in the surrounding material.
