For over a decade, scientists have been curious about the long fractures on Europa’s icy surface and the darker-colored material they contain, as well as other relatively young geological […]

Highest-Resolution Views Yet Reveal Ceres' Mysterious Bright Spots, Seemingly Comprised of Multiple ‘Icy Spots’

This image of Ceres was taken by NASA’s Dawn spacecraft on May 4, 2015, from a distance of 8,400 miles (13,600 kilometers), in its RC3 mapping orbit. The brightest spots within a crater in the northern hemisphere are revealed to be composed of many smaller spots. The image resolution is 0.8 mile (1.3 kilometers) […]

Enceladus' Water Geysers May Be 'Curtain Eruptions' According to New Study

The water vapor jets on Enceladus are now thought to mostly be more like diffuse “curtains” rather than separate plumes. Image Credit: NASA/JPL-Caltech/SSI/PSI

The water vapor geysers on Saturn’s moon Enceladus are one of the most fascinating phenomena in the Solar System; the jets spray far out into space in a dazzling display unseen […]

Astronomers Find First Evidence of Possible Volcanic Activity On a Super-Earth Exoplanet

Discovering new exoplanets has become rather routine in the last few years, but determining just what conditions exist on any of them is naturally more difficult, since […]

NASA Actively Working to ‘Save Opportunity and LRO’ From Budget Cutters' Axe

Opportunity at Spirit of Saint Louis crater scanning into Marathon Valley and Endeavour crater from current location on Mars in April 2015 in this photo mosaic. The crater, featuring an odd mound of rocks, is the gateway to Marathon Valley and exposures of water altered clay minerals. This pancam camera photo mosaic was assembled […]

Scientists have discovered a vast network of salty aquifers beneath the surface of Antarctica, thanks to an airborne imaging system used there for the first time. The finding may have interesting implications for the […]

New NASA NExSS Coalition to Lead Search for Life on Distant Exoplanets

NASA’s NExSS collaboration will bring together scientists from diverse backgrounds to help search for evidence of life in other Solar Systems. Image Credit: NASA

The search for, and discovery of, exoplanets orbiting other stars has become a full-fledged endeavour in recent years, with thousands found so far and more being discovered practically every week. […]

Thunderstorms are a powerful force of nature, but the ones we experience on Earth are dwarfed by the ones on the gas giant planet Saturn. They are huge and can be larger […]

Dawn Divulges Diverse Terrain in First Color Map of Ceres and North Pole View

This map-projected view of Ceres was created from images taken by NASA’s Dawn spacecraft during its initial approach to the dwarf planet, prior to being captured into orbit in March 2015. Credits: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA

Scientists spearheading the Dawn mission to dwarf planet Ceres have published the first color map of the mysterious world since the […]
