The existence of neon gas in our Moon’s ultra-thin atmosphere has been confirmed for the first time, by NASA’s Lunar Atmosphere and […]

New Study Suggests Abundance of Nitrogen on Pluto May Be Due to Cryovolcanism

A spectacular image of Pluto's atmosphere backlit by the Sun, taken during New Horizons' closest approach to Pluto on July 14. The bright halo of Pluto's atmosphere is caused by the scattering of sunlight from nitrogen, a compound that dominates the planet's atmosphere. A new study suggests that the source of all this nitrogen might be cryovolcanism on the distant planet. Image Credit: NASA/JHUAPL/SwRI

The intriguing bright spots on dwarf planet/asteroid Ceres have been fascinating the public and scientists alike for the past few months, and […]

New Petition Aims to Restore Pluto's Planetary Status

A breathtaking montage of Pluto and Charon, assembled from separate images that were taken on July 13 and 14 from NASA’s New Horizons spacecraft, as the latter was making its historic close fly by of the distant dwarf planet and its system of moons. New Horizons’ highly successful mission has provided a new thrust […]

Historic First Close-Ups From New Horizons Reveals Dramatic Worlds Billions of Miles Away

Pluto’s largest moon Charon (left) has a surprising youthful and varied terrain, with cliffs, troughs, and a dark marking nicknamed “Mordor” in the moon’s north polar region. New close-up images of a region near Pluto’s equator (right) reveal a giant surprise: a range of youthful mountains rising as high as 11,000 feet (3,500 meters) […]
