Pluto Once Had Rivers and Lakes of Liquid Nitrogen, New Horizons Data Suggests

One of the most surprising discoveries in recent years in the outer Solar System is that there are small moons which have oceans inside them. Jupiter’s moon Europa and Saturn’s moon Enceladus are now known to have global […]

Data From New Horizons Reveals More Water Ice on Pluto Than Previously Thought

New Horizons has shown Pluto to be a diverse world, more so than many scientists had anticipated, with tall mountain ranges, vast glaciers, a blue-colored […]

Stunning New Images of Pluto's Surface Are Best Yet from New Horizons Mission

One of NASA’s primary objectives, and the one which most excites the general public, is the search for evidence of life elsewhere, whether in our own Solar System or on some […]

GJ 1132b: Nearest Earth-Sized Exoplanet Discovered So Far May Be a 'Venus Twin'

Astronomers have discovered another Earth-sized exoplanet that is the closest one to our own Solar System found so far, but it might not be a nice place […]

The Saline Slopes of Mars: NASA Confirms Evidence for Flowing Liquid Water

False color image of RSL on slopes in Hale crater. The blue color is thought not to be related to their formation, but instead are from the presence of the mineral pyroxene. The image is produced by draping an orthorectified (Infrared-Red-Blue/Green(IRB)) false color image (ESP_030570_1440) on a Digital Terrain Model (DTM) of the same site produced by High Resolution Imaging Science Experiment (University of Arizona). Vertical exaggeration is 1.5.

One of the primary goals in the search for exoplanets is to, hopefully, find an Earth analog or “Earth twin,” an alien world similar to our own. That search is still […]

Two Days Prior to Closest Approach New Horizons Images Pluto's Charon-Facing Hemisphere for the Last Time

Pluto’s Charon-facing hemisphere, as seen by the New Horizons spacecraft for the last time on july 11, from a distance of 4 million km away. The image clearly shows newly-resolved linear features above the equatorial region that intersect, suggestive of polygonal shapes. Image Credit/Caption: NASA/JHUAPL/SWRI

With just two days remaining before New Horizons zips […]
