  • Venus can be seen as a black dot eclipsing the Sun in this image from 2012. Venus orbits too close to the Sun to the planet to be habitable for life as we know it. Venus experiences a runaway greenhouse and the average surface temperatures are thought to be around 864ºF. Image Credit: NASA/SDO & the AIA, EVE, and HMI teams; Digital Composition: Peter L. Dove
    Astrobiologists have shed new light on the future habitability of Earth, and the tools they are using could also tell us about habitability around distant stars.

  • Droplets on a leg of the Mars Phoenix lander are seen to darken and coalesce. Nilton Renno, a professor in the Department of Atmospheric, Oceanic and Space Sciences says this is evidence that they are made of liquid water. Credit: NASA/JPL-Caltech/University of Arizona/Max Planck Institute
    Researchers supported by the Exo and Evolutionary Biology element of NASA Astrobiology Program have discovered that a salt on Mars could cause liquid water to form when it comes into contact with water ice.

  • This MARCI image from MRO is a composite mosaic of the north polar cap. The images were taken at midnight, 6 a.m., noon, and 6 p.m. martian time, during the summer when the sun is always shining in the polar region. The image shows the mostly water-ice perennial cap (white area), sitting atop the north polar layered materials (light tan immediately adjacent to the ice), and the dark circumpolar dunes.
