The mystery of an unusual feature in one of Titan’s hydrocarbon seas, dubbed the “mystery island,” has taken an interesting turn. After apparently disappearing following its initial [...]

'Drill, Baby, Drill' Replaces 'Drive, Drive, Drive' as Curiosity Gets First Taste of Mount Sharp Foothills

'Engines in Post-Shutdown Standby': 20 Years Since STS-68 (Part 1)

For the second time in less than six months, the Space Radar Laboratory (SRL) rode Endeavour into orbit in September-October 1994. However, the launch of STS-68 was delayed extensively, following the shuttle program’s last Redundant Set Launch Sequencer (RSLS) abort. Photo Credit: NASA

One day in the summer of 1993, astronaut Tom Jones was [...]

New Dust Map of Galaxy Casts Doubts on Gravitational Waves Discovery

A landing site has now been chosen for the Rosetta spacecraft’s lander, Philae, on comet 67P/Churyumov–Gerasimenko, it was announced this morning. After several candidate landing sites had been considered, site J has now [...]

Plate Tectonics May Increase Chances for Life on Europa

Europa, with its subsurface ocean, and now evidence for plate tectonics, is a primary goal of exploration in the search for alien life. Processed image copyright: Ted Stryk. Image Credit: NASA/JPL-Caltech/Ted Stryk

Jupiter’s moon Europa is a fascinating little world, but particularly so for one reason: water. It’s deep alien ocean underneath the surface [...]

Rainfall on Titan May Create Propane Aquifers, Study Suggests

Saturn’s largest moon, Titan, is a very alien yet eerily Earth-like world, with rain, rivers, lakes, and seas; seen from above, the landscape has a familiar look to it. But [...]

Curiosity Rover Moving Onward to Martian Mountain Goal, Shuns Drilling and Slippery Dunes

NASA’s Curiosity rover abandons drill campaign at “Bonanza King” rock outcrop after hammer test (inset at right) determined it was unsuitable as a potential fourth drill site, in this photo mosaic view captured on Aug. 20, 2014, Sol 724. Note the background of sand dune ripples and deep wheel tracks inside Hidden Valley that [...]

Astronomers Witness Asteroid Smash-Up Around Sun-Like Star
