The hunt for a real (and bigger) Death Star is on

Last month, NASA's planet-hunting Kepler spacecraft suffered a potentially mission-ending malfunction, prompting the eyes of many astronomers and space geeks to grow a little misty. The crippling blow came just as data from Kepler had begun to identify more distant Earth-like planets within the habitable zone.

What's not as widely known, however, is that Kepler data isn't used just to hunt for planets that could potentially support life, it's also been tapped by some intrepid explorers to search for stellar and planetary megastructures created by far-flung advanced societies. Since we've yet to send anything into … Read more

A look back at NASA's planet-pinpointing space 'scope

NASA announced this week that a key piece of gear on its Kepler space telescope has run into trouble. And though the space agency hasn't given up on a jump-start, the mission may well be at risk.

It's already gone well beyond its planned duration, however, and presented us with many fascinating discoveries.

In this gallery, we take a look back at that mission -- at Kepler's intriguing quest to find Earth-like, life-friendly planets among the Milky Way's many stars.

NASA's Kepler telescope crippled by technical failures

The Kepler space observatory has been a source of great wonder since it first launched in 2009. It has turned its eyes out into the great vastness of space and seen new planetary systems and potentially life-supporting planets. The telescope's original 3.5-year mission was extended into 2016, but that may now come to a halt as serious technical issues take a toll.

Kepler is able to look out in certain directions thanks to four reaction wheels that are used to point the spacecraft. As of Wednesday, two out of four reaction wheels have failed.… Read more

NASA's Kepler telescope and the quest for life out there

(CBS News) The question "Is anybody out there?" grows more tantalizing with the discovery of each new far-off planet. Barry Petersen has been talking to scientists searching for clues...

Starry nights inspire wonder, and wondering: Is there life out there?

So how fitting that, in March 2009, NASA launched the planet-hunting telescope Kepler into the night sky.

Look up tonight at the constellation Cygnus -- also known as the Northern Cross -- and up in that one slice of sky is where Kepler has been scanning 150,000 stars every 30 minutes for the last four years.

NASA has found 3 nice, habitable planets for us to choose from

NASA, that wily band of intergalactic peepers, says it's spied three distant planets in two different solar systems that are the proper distance from their suns to make them potentially habitable.

I can almost hear Elon Musk's pitch for time-shares in the Kepler-62 and Kepler-69 systems already.… Read more

NASA's Kepler spacecraft to reveal new planetary discoveries?

NASA's Kepler spacecraft has been in hot pursuit of extraterrestrial life for four years now. And, on Thursday, it's letting people know just what it's found lurking in the Milky Way.

NASA is holding a Kepler briefing at 11 a.m. PT on Thursday. It will be broadcast live on NASA Television and on UStream. The agency will also host a moderated Web chat with Kepler Deputy Project Scientist Nick Gautier of NASA's Jet Propulsion Lab. During the briefing, people can submit questions to the Kepler scientists via Twitter with the hashtag #AskNASA.

Nvidia CEO unveils next two gens of Tegra, dubbed Logan, Parker

Nvidia CEO Jen-Hsun Huang today talked up the chipmaker's next two generations of mobile chip, saying the Tegra chip line will show a 100-times improvement in strength from the first chip to the fifth.

The current Tegra chip, Tegra 4, hit the market earlier this year. The next generation, coming later this year, is code-named Logan, while the fifth generation of Tegra is code-named Parker, Huang said at the company's GPU developers' conference.

Logan will incorporate Nvidia's Kepler GPU, which currently is dominating the discrete graphics market. It also will include CUDA, Nvidia's programming model for … Read more

New clues emerge on origin of Kepler's famous supernova

More than 400 years after skywatchers -- including astronomer Johannes Kepler -- witnessed the appearance of a spectacular new star in the night sky, astronomers have uncovered important new details about the origins of this famous supernova.

The supernova remnant contains iron-rich material surrounded by an expanding shock wave that scarfs up interstellar gas and dust in its path. The ensuing shroud of gas and dust is estimated to be 14 light-years wide and is expanding at 4 million miles per hour.

A new study published online and in the February 10 issue of The Astrophysical Journal found that the … Read more

Researchers develop flexible, transparent image sensor

Researchers from the Institute of Computer Graphics at Johannes Kepler University in Linz, Austria, have developed a way to capture images on a flexible sheet of plastic. Unlike traditional image sensors that use circuits and other internal structures to develop an image, this new solution is fully transparent.

This is no ordinary sheet of plastic though. The sensor is a polymer film (luminescent concentrator) containing a multitude of fluorescent particles that absorb a specific wavelength of light. It then transmits this light at a longer wavelength to optical sensors at the side of the sheet, which captures it all, reconstructing … Read more
