For several years now the Kepler Space Telescope, as well as other telescopes, has been discovering an increasing number of exoplanets, with over 2,000 such confirmed worlds found so far (and nearly 5,000 candidates). Today, NASA […]

Evidence from Curiosity Rover Shows Mars Once Had Oxygen-Rich Atmosphere

Mars' atmosphere is thin, dry and cold now, but it used to be thicker and contained a lot more oxygen. Image Credit: ESO/M. Kornmesser

Mars’ atmosphere is thin and cold, composed primarily of carbon dioxide along with other trace gases and some water vapor. Evidence has continued to mount, however, that the rarified atmosphere […]

New 'KEM' Proposal Would Extend New Horizons Post-Pluto Mission to 2021

If approved by NASA, the KEM proposal will allow New Horizons to continue its study of the outer fringes of the Solar System until 2021, including a flyby of 2014 MU69. Image Credit: NASA/JHUAPL/SwRI
