An advanced new six-unit (6U) CubeSat is being designed by a NASA skunkworks team, for possible deployment from the International Space Station by January 2016. The […]

Living On the Edge: Life Under the Ice (Part 1)

After drilling through the 800-meter-thick ice sheet that covers subglacial Lake Whillans in western Antarctica, a U.S. research team discovered a thriving microbial ecosystem on the lake floor that hasn’t been reached by sunlight possibly for up to a million years. The image shows the view down the bore hole as the drill […]

Smoking Gun Found for Big Bang Birth of the Universe

Astronomers today announced an exciting discovery: the first direct evidence for what happened during the first few seconds or so of the birth of […]

Galaxy’s Gamma-Ray Flares Erupted From Its Black Hole

Prior to its strong outbursts in 2011, blazar 4C +71.07 was a weak source for Fermi’s LAT. These images centered on 4C +71.07 show the rate at which the LAT detected gamma rays with energies above 100 million electron volts (lighter colors equal higher rates). The image at left covers 2.5 years, from […]
