The outer Solar System has been a busy place lately, with the ongoing Cassini mission at Saturn and New Horizons’ recent spectacular flyby of Pluto. Literally in-between those two worlds, however, it has been […]

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 […]

Just Add Water: Scientists Explain Saturn's Powerful Thunderstorms

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 […]

Two New Exoplanet Findings Bring Us Closer to Discovering Other Earth-Like Worlds

When it comes to exoplanets, the most exciting for many┬ápeople are, of course, the ones which may be┬áthe most Earth-like, since these are regarded as the most likely to possibly support some form […]

New Uranus-Like 'Ice Giant' Exoplanet Discovered

Many different kinds of exoplanets have been found by astronomers, from giant “hot Jupiters” and “super Earths” to smaller rocky worlds like Earth or Mars. Now, another type has been discovered, an “ice giant” similar to Uranus or Neptune in our […]

LRO Continues to Examine Lunar Helium

In August, AmericaSpace reported about the detection of helium in the Moon’s atmosphere. A new paper by the same group now reports on how the amount of helium varies as the lunar day progresses.
