Jupiter has often been referred to as the King of Planets, and for good reason, as it is a massive gas giant, much larger than Earth and the largest planet in our Solar System. It is more than 2.5 times as massive as all the other […]

Exoplanets are now being discovered by the thousands, but most are so far away that determining anything specific about their composition or atmosphere is currently very difficult. But technology keeps advancing, and scientists are now starting to be […]

New 2016 NASA Budget Fully Funds Europa Mission, Including Lander

A view many have been waiting for - artist's concept of the surface of Europa. The new NASA budget brings this closer to reality, with funding for not only a flyby probe, but also a lander. Image Credit: NASA/JPL-Caltech
