Space Spin » Bully galaxy rules the neighbourhood

In general, galaxies can be thought of as "social" -- hanging out in groups and frequently interacting. However, this recent Hubble Space Telescope image highlights how some galaxies appear to be hungry loners. These cosmic oddities have set astronomers on the "case of the missing neighbour galaxies"....

Space Spin » Winds of change: How black holes may shape galaxies

New observations from NASA's Chandra X-ray Observatory provide evidence for powerful winds blowing away from the vicinity of a supermassive black hole in a nearby galaxy. This discovery indicates that "average" supermassive black holes may play an important role in the evolution of the galaxies in which they reside. For years, astronomers have kn...

Space Spin » Mars Reconnaissance Orbiter speeds past data milestone

NASA's newest Mars orbiter, completing its fourth year at the Red Planet this week, has just passed a data-volume milestone unimaginable a generation ago and still difficult to fathom: 100 terabits. That 100 trillion bits of information is more data than in 35 hours of uncompressed high-definition video. It's also more than three times the amount...

Space Spin » Radar map of buried martian ice adds to climate record

Extensive radar mapping of the middle-latitude region of northern Mars shows that thick masses of buried ice are quite common beneath protective coverings of rubble. The ability of NASA's Mars Reconnaissance Orbiter to continue charting the locations of these hidden glaciers and ice-filled valleys -- first confirmed by radar two years ago -- adds...

Space Spin » Fermi probes 'dragons' of the gamma-ray sky

One of the pleasures of perusing ancient maps is locating regions so poorly explored that mapmakers warned of dragons and sea monsters. Now, astronomers using NASA's Fermi Gamma-ray Space Telescope find themselves in the same situation as cartographers of old. A new study of the ever-present fog of gamma rays from sources outside our galaxy shows...

Space Spin » Mini-SAR finds ice deposits at moon's north pole; Additional evidence of water activity on moon

Using data from a NASA radar that flew aboard India's Chandrayaan-1 spacecraft, scientists have detected ice deposits near the moon's north pole. NASA's Mini-SAR instrument, a lightweight, synthetic aperture radar, found more than 40 small craters with water ice. The craters range in size from 1 to 9 miles (2 to15 km) in diameter. Although the to...

Space Spin » Mars Odyssey still hears nothing from Phoenix

NASA's Phoenix Mars Lander showed no sign during February that it has revived itself after the northern Mars winter. NASA's Mars Odyssey orbiter will check again in early April. The solar-powered Phoenix lander operated for two months longer than its planned three-month mission in the Martian arctic in 2008. It was not designed to withstand winte...

The Planetary Society Weblog » Unbelievably spectacular flight through Candor Chasma

This is one of the things that came out during LPSC last week and all I could do at the time was Tweet it, which doesn't serve most of my readers, I realize.

The Planetary Society Weblog » Cassini's Helene flyby

I was much anticipating Cassini's encounter with Helene on Wednesday.
