Where are all those high energy positrons coming from?

[CLICK ON IMAGE FOR HIGH RESOLUTION, Ron Garan, STS-134 Crew, Expedition 28 Crew, NASA] Where did all these high energy positrons come from? The Alpha Magnetic Spectrometer (AMS-02) onboard the International Space Station (ISS) has been meticulously recording how often it is struck by both high energy electrons and positrons since 2011. After accumulating years […]

Looking down on the Perseid meteor shower from space

CLICK ON IMAGE FOR HIGH RESOLUTION / Ron Garan, ISS Expedition 28 Crew, NASA [People on] planet Earth typically watch meteor showers by looking up. But this remarkable view, captured on August 13, 2011 by astronaut Ron Garan, caught a Perseid meteor by looking down. From Garan’s perspective onboard the International Space Station orbiting at […]

Wanted: Reusable spaceplane to launch satellites

Wanted: Reusable spaceplane to launch satellites

So DARPA wants a reusable spaceplane. I mean, who doesn’t? For decades, space experts have tried to design quick-turnover, reusable launch systems. So far, however, no one has made one that works. “There really isn’t any kind of vehicle today that does exactly what they’re asking people to do,” Micah Walter-Range, director of research and […]

NASA: Astronomers think every star in Milky Way ‘has at least one planet’

Cambridge, Mass – NASA predicts that 100 million worlds in our own Milky Way galaxy may host alien life, and space program scientists estimate that humans will be able to find life within two decades. Speaking at NASA’s Washington headquarters on Monday, the space agency outlined a plan to search for alien life using current […]

What we don’t know about this breath-taking view of Saturn’s blue and gold

[CLICK ON IMAGE FOR HIGH RESOLUTION, Cassini Imaging Team, SSI, JPL, ESA, NASA] Why is Saturn partly blue? The above picture of Saturn approximates what a human would see if hovering close to the giant ringed world. The above picture was taken in 2006 March by the robot Cassini spacecraft now orbiting Saturn. Here Saturn’s […]
