A new glimpse of a well-known supernova could provide new clues about how dying stars affect their surroundings. Read more…
The sands of time are running out for the central star of this the Hourglass Nebula. With its nuclear fuel exhausted, this brief, spectacular, closing phase of a sun-like star’s life occurs as its outer layers are ejected and its core becomes a cooling, fading white dwarf. In 1995, astronomers used the Hubble Space Telescope [...]

A new survey of asteroids near Earth shows these space rocks are a mixed bag, with some shiny and bright, others dark and dull. Read more…
The Expedition 24 crew on the International Space Station photographed this image of polar mesospheric clouds illuminated by an orbital sunrise. Polar mesospheric, or noctilucent (“night shining”), clouds usually are seen at twilight, following the setting of the sun below the horizon and darkening of Earth’s surface. Occasionally the station’s orbital track becomes nearly parallel [...]
Backdropped by red hills, the Development Motor-2, or DM-2, ignites during an Aug. 31, 2010, static test that was conducted by ATK Aerospace Systems in Promontory, Utah. DM-2, the largest and most powerful solid rocket motor designed for flight, is managed by the Ares Projects Office at NASA’s Marshall Space Flight Center in Huntsville, Ala. [...]
