The one ring is back, and it’s beautiful.

What you see here is the aftermath of stellar death, rediscovered after NASA temporarily lost the ability to watch it play out. Astronomers tracked supernova 1987A after its discovery that year, picking up insights into what happens after a huge star expends itself. But in 2004, the Hubble Space Telescope’s Space Telescope Imaging Spectrograph went kaput. The May 2009 space shuttle servicing mission repaired this eye in the sky, leading to a study in this week’s edition of the journal Science that reveals what’s behind this fluorescent view, and why that ring shines so brightly.

In the Hubble images of SN1987A, what looks like a string of pearls appears around the site of the former star. These “pearls” of circumstellar material are made up of material that was emitted before the star exploded, as it was preparing to die. Light from the supernova itself illuminates the pearls (as seen in these images of the supernova), and as the supernova debris interacts with the circumstellar material over time, the pearls will eventually form a continuous ring around the remnant, [lead researcher Kevin] France said.

This isn’t a one-way, street either. As the shock waves blast the debris ring, the debris ring can deflect them.

They also think that some of the shock waves are bouncing back off the debris. The team has used Hubble’s imaging spectrograph to map the velocity and chemical composition of this moving gas. “Although we always knew it was there, this is the first time we’ve actually been able to see this reverse shock [in supernova 1987A]“, says Richard McCray, an astrophysicist at the University of Colorado and a co-author on the study.

This supernova remnant is close to 170,000 light years away. Hubble’s refurbished imaging power has allowed the team to investigate the elements in the area—the stuff of the former star now spilled out, including heavy elements like silicon and iron.

Such research is crucial to understanding the bigger picture of how supernovae affect their environment, says France. Supernovae have an important role in the evolution of galaxies, because they input a massive amount of energy into the environment, and they are the source of most heavy elements, such as iron, he says.

Hugh Pickens writes “The NY Times reports that Consumer Watchdog is running a 540-square-foot video billboard advertisement in Times Square, New York that shows Google CEO Eric Schmidt as an ingratiating ice cream truck driver who knows everything about everyone and happily offers free ice cream in exchange for full body scans. The group says its goal is to push Congress and the Federal Trade Commission to create a Do Not Track Me list, similar to the Do Not Call list developed to prevent telemarketers from aggressively calling consumers. ‘Do you want Google or any other online company looking over your shoulder and tracking your every move online just so it can increase its profits?’ writes the group’s president, Jamie Curtis, at the group’s web site. ‘Consumers have a right to privacy. They should control how their information is gathered and what it is used for.’ The FTC’s consumer affairs group had no comment on whether the agency is considering creating a Do Not Track Me list.”

jamie writes “A grassroots campaign has begun to get Stephen Colbert to hold a rally on the steps of the Lincoln Memorial to counter Glenn Beck’s recent ‘Restoring Honor’ event. The would-be rally has been dubbed ‘Restoring Truthiness‘ and was inspired by a recent post on Reddit, where a young woman wondered if the only way to point out the absurdity of the Tea Party’s rally would be if Colbert mirrored it with his own Colbert Nation.’”

An anonymous reader writes “‘Always bet on Duke.’ It seems he was right about himself, at least. The longest, most storied in-development game in history seems like it’s finally going to be released by Gearbox Software sometime within the next year. ‘According to Pitchford, Gearbox began finishing Duke Nukem Forever in late 2009. “Clearly the game hadn’t been finished at 3D Realms but a lot of content had been created,” he says. “The approach and investment and process at 3D Realms didn’t quite make it, and it cracked at the end. With Gearbox Software we brought all those pieces together. It’s the game it was meant to be.” The game is currently expected to ship in 2010 although given its history Pitchford is understandably reluctant to be more specific.’”

Jake writes with this excerpt from Ars:
“Microsoft is warning about a new piece of malware, Rogue:MSIL/Zeven, that auto-detects a user’s browser and then imitates the relevant malware warning pages from Internet Explorer, Firefox, or Chrome. The fake warning pages are very similar to the real thing; you have to look closely to realize they aren’t the real thing. The ploy is a basic social engineering scheme, but in this case the malware authors are relying on the user’s trust in their browser, a tactic that hasn’t been seen before. Beyond the warning pages, the actual malware looks like the real deal: it allows you to scan files, tells you when you’re behind on your updates, and enables you to change your security and privacy settings. Performing a scan results in the product finding malicious files, but of course it cannot delete them unless you update, which requires paying for the full version. Attempting to buy the product will open an HTML window that provides a useless ‘Safe Browsing Mode’ with high-strength encryption. To top it all off, the rogue antivirus webpage looks awfully similar to the Microsoft Security Essentials webpage; even the awards received by MSE and a link to the Microsoft Malware Protection Center have been copied.”

waderoush writes “On top of all the other features that it has crammed into iTunes, Apple this week added Ping, a Facebook-like social network for music discovery. It’s all part of the company’s plan to dominate the world of consumer media, but Xconomy argues that this time, Apple may have gone a bridge too far. iTunes, nearing its tenth birthday, started out merely as a program for ripping CDs, and has grown increasingly creaky and impenetrable as Apple has added more and more cruft, the article argues. The company won’t have a stable base for its new media empire until it rebuilds iTunes from scratch — perhaps along the lines suggested by its other new product this week, the revamped Apple TV.”

Lucas123 writes “After a storage area network in a data center run by Northrop Grumman went down last week, crippling 26 state agencies’ websites — some for more than a week — Northrop Grumman has now apologized to Virginia, saying it will learn from its mistakes in order to recover systems faster in the future. Northrop’s $2.6 billion service contract with Virginia’s government has come under harsh criticism in the past for service outages, along with project delays and cost overruns.”

Dangerous_Minds writes “Drew Wilson has been following HADOPI (France’s three strikes law) a lot lately, and the latest developments are that the French ISPs and the French government are edging closer to a full-on war over compensation. The French government apparently requested that ISPs send an invoice of the bills after a certain period of time, but the French ISPs don’t feel this is good enough — probably because of worries that the compensation the government will ultimately provide won’t be enough. The ISPs are demanding adequate compensation, and if the government doesn’t give it to them, they simply will not hand over evidence required to enforce HADOPI law. While HADOPI demands that ISPs cooperate, speculation suggests that if the government takes ISPs to court, the ISPs will simply rely on constitutional jurisprudence to shield them from liability (translation).”

In May we discussed news that producers of the film The Hurt Locker filed a lawsuit against 5,000 John Does, known only by their IP addresses at the time, for sharing the movie over peer-to-peer sites. Now, reader suraj.sun notes that subpoenas for the lawsuit are finally going out.
“Qwest Communications on Monday notified a customer in Denver that the Internet service provider has received a subpoena from lawyers representing Voltage Pictures, the production company that made The Hurt Locker. … In legal documents, Voltage Pictures has blamed the movie’s relatively poor domestic performance on illegal file sharing. As of March 21, the movie had grossed $16 million domestically, but took in $40 million overall. According to reports, the film’s production budget was $15 million. The film leaked to the Web five months before the movie’s US debut. … For allegedly downloading The Hurt Locker, DGW told the Qwest customer from Denver that settling the case early would cost $2,900, according to documents reviewed by CNET.”

neo12 writes with news that Hewlett-Packard is teaming with Hynix Semiconductor, the world’s second-largest producer of memory chips, to mass produce memristors for the first time. Quoting the BBC:
“HP says the first memristors should be widely available in about three years. The devices started as a theoretical prediction in 1971 but HP’s demonstration and publication of a real working device has put them on a possible roadmap to replace memory chips or even hard drives. … Steve Furber, professor of computer engineering at the University of Manchester, explained that the potential benefits lie in the fact that memristors are ‘much simpler in principle than transistors. Because they are formed as a film between two wires, they don’t have to be implanted into the silicon surface — as do transistors, which form the storage locations in Flash — so they could be built in layers in 3D,’ he told BBC News. ‘Of course, the devil is in the detail, and I don’t think the manufacturing challenges have been fully exposed yet.’”
