A new type of supernova remnant still holds the embers of the fireball that first blossomed thousands of years ago. The remnant gas retains ions with the imprint of temperatures 10,000 times hotter than the sun's surface, according to scientists who made the observations with the Japan-U.S. Suzaku space observatory.
Good news for astrophysicists and fans of massive thermonuclear explosions alike: a team of mathematicians at the DOE's Lawrence Berkeley National Laboratory, working alongside two astrophysicists from Stony Brook University and U.C. Santa Cruz, have modeled the hours leading up to a Type Ia supernova, capturing the gritty details of the cataclysmic death of a white dwarf star for the first time.
The newly-refurbished Hubble Space Telescope sent back its first breathtaking images after being repaired in September. Here, Nebula NGC 6302 with its butterfly wings of 36,000-degree gas.
We always like to look forward to bigger and better tech, but NASA's Hubble Space Telescope, though it's been around the block, still holds a special place in every geek's heart. Now the freshly repaired and upgraded telescope has resumed churning out enough images of cosmic glory to turn anyone's head.
Over the past several decades, the promise of the "car of tomorrow" has remained unfulfilled, while the problems it was supposed to solve have only intensified. The average price of a gallon of gas is higher than at any time since the early 1980s. The Middle East seems more volatile than ever. And even climate skeptics are starting to admit that the carbon we´re pumping into the atmosphere might have disastrous consequences. To these circumstances, automakers have responded with a fleet of cars that averages 21 miles per gallon, about four miles per gallon worse than the Model T.
In a rush to flee the solar system? Scientists have an interstellar travel plan, but it entails a brief stint outside the known universe

What: A spacecraft that travels at faster-than-light speeds by distorting, or "warping," the fabric of spacetime. Instead of trying to move through space, the warp drive moves space itself. The ship sits inside a bubble of spacetime bound by a negative energy field that races across the cosmos.

Texas Star Party, May 1-8Those yearning for dark skies and the camaraderie of star enthusiasts might wish to make the trek to the 27th annual Texas Star Party. The event features a week of galaxy-gazing and plenary lectures. This year’s speakers include Robert T. Mitchell, the project manager of the Cassini mission, and Stephanie McLaughlin, a project coordinator for NASA’s Deep Impact mission. The Star Party has a strict “no lights” policy from sundown to sunup.
