The Martian volcano Olympus Mons is about three times the height of Mount Everest, but it’s the small details that Rice University professors Patrick McGovern and Julia Morgan are looking at in thinking about whether the Red Planet ever had — or still supports — life.

NASA Hubble new evidence for dark matter around small galaxies
These four dwarf galaxies are part of a census of small galaxies in the tumultuous heart of the nearby Perseus galaxy cluster. The galaxies appear smooth and symmetrical, suggesting that they have not been tidally disrupted by the pull of gravity in the dense cluster environment. Larger galaxies around them, however, are being ripped apart [...]

The three pictured galaxies — NGC 7173 (middle left), NCG 7174 (middle right) and NGC 7176 (lower right) — are part of the Hickson Compact Group 90, named after astronomer Paul Hickson, who first catalogued these small clusters of galaxies in the 1980s. NGC 7173 and NGC 7176 appear to be smooth, normal elliptical galaxies [...]
Artist’s impression of how the surface of Pluto might look, according to one of the two models that a team of astronomers has developed to account for the observed properties of Pluto’s atmosphere, as studied with CRIRES. The image shows patches of pure methane on the surface. At the distance of Pluto, the Sun appears [...]

The anthropology world is all abuzz with a discovery in Africa that’s knocking scientists off their feet.
It’s the finding of 1.5 million-year-old fossilized human footprints in Kenya at Rutgers University’s Koobi Fora [...]
This image of Comet Lulin taken Jan. 28 merges data acquired by Swift’s Ultraviolet/Optical Telescope (blue and green) and X-Ray Telescope (red). At the time of the observation, the comet was 99.5 million miles from Earth and 115.3 million miles from the sun.

At a meeting in Washington last week, National Aeronautics and Space Administration and European Space Agency officials decided to continue pursuing studies of a mission to Jupiter and its four largest moons, and to plan for another potential [...]
The Lunar Crater Observation and Sensing Satellite (LCROSS) completed ‘mate match’ tests at Northrop Grumman’s manufacturing facilities in Redondo Beach, Calif. The test are designed to test the fit of the adapter rings used to connect LCROSS with the Lunar Reconnaissance Orbiter on one end and the Centaur rocket on the other. The spacecraft and [...]
Caption: This image from ESO’s Very Large Telescope Interferometer is one of the sharpest color images ever made. It shows the Mira-like star T Leporis in great detail. The central disc is the surface of the star, which is surrounded by a spherical shell of molecular material expelled from the star. In order to appreciate [...]
