Mars used to have a thicker atmosphere and water on its surface, but what happened to that atmosphere has been a mystery. New research may finally help answer that question. Image Credit: M. Kornmesser/ESO

The question of how Mars changed from a once wet world to the much colder and drier one we see […]

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 […]

On the Final Path: New Horizons Executes Last Course Correction Maneuver Prior to Pluto Closest Approach

Flight controllers in the New Horizons Mission Operations Center at the Johns Hopkins University Applied Physics Laboratory, monitor data from NASA’s New Horizons spacecraft on June 30, after a short course-correction maneuver refined New Horizons path toward a flyby of Pluto on July 14.

New Horizons Mission Returns First Images of Pluto's Smallest Known Moons Kerberos and Styx

NASA’s New Horizons spacecraft has just returned the first long-range images of Kerberos and Styx, the two smallest moons of Pluto. Each animation consists of five 10-second frames which were taken with the onboard LORRI camera between April 25 and May 1At left is the initial set of raw images, while at the center […]

Hubble Reveals Three Potential Deep Space Objects for New Horizons to Explore After Pluto

An artist’s impression of a Kuiper Belt object (KBO), located on the outer rim of our Solar System at a staggering distance of 4 billion miles from the Sun. A HST survey uncovered three KBOs that are potentially reachable by NASA’s New Horizons spacecraft after it passes by Pluto in mid-2015Image Credit: NASA, ESA, […]

Plate Tectonics May Increase Chances for Life on Europa

Europa, with its subsurface ocean, and now evidence for plate tectonics, is a primary goal of exploration in the search for alien life. Processed image copyright: Ted Stryk. Image Credit: NASA/JPL-Caltech/Ted Stryk

Jupiter’s moon Europa is a fascinating little world, but particularly so for one reason: water. It’s deep alien ocean underneath the surface […]
