New research shows the early lunar crust which makes up the surface of the Moon was considerably enriched in water more than 4 billion years ago, counter to previously held ...

Astronomers have made the rare discovery of a small, cold exoplanet and its massive outer companion -- shedding light on the formation of planets like ...

Researchers have taken the first steps toward finding liquid solvents that may someday help extract critical building materials from lunar and Martian-rock dust, an important piece in making ...

Beta Pictoris, a young planetary system located just 63 light-years away, continues to intrigue scientists even after decades of in-depth study. It possesses the first dust disk imaged around another ...

Astronomers have found a brown dwarf (an object more massive than Jupiter but smaller than a star) with infrared emission from methane, likely due to energy in its upper atmosphere. This is an ...

Analysis of iron meteorites from the earliest years of the solar system indicate that the planetary 'seeds' that ultimately formed Earth contained ...

Astrophysicists outline the links between atmospheric oxygen and the potential rise of advanced technology on distant ...

Imagine blasting off on a multiyear voyage to Mars, fueled by a diet of bland, prepackaged meals. As space agencies plan for longer missions, they're grappling with the challenge of how to best ...
