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 […]

'Old Earths': The Search for Ancient and Habitable (But Dying) Exoplanets

The search for liquid water on Mars is one that has been on-going for decades. It can’t exist for long on the surface, as it will quickly sublimate into the cold, thin atmosphere. Aquifers deep […]

Buried Glaciers Have Enough Ice to Cover Entire Surface of Mars, According to New Study

The closest star system to our own Sun may have two Earth-sized exoplanets orbiting it, a new study has shown based on observations by the […]

Rosetta Makes First Detection of Cometary Molecular Nitrogen, Seeks Signals From Philae Lander

Rosetta has made the first detection of molecular nitrogen at a comet. The results provide clues about the temperature environment in which Comet 67P/Churyumov–Gerasimenko formed. Credit: ESA/ATG medialab; comet: ESA/Rosetta/NavCam – CC BY-SA IGO 3.0

Rosetta, humankind’s first spacecraft to orbit a comet, has now made the first detection of molecular nitrogen (N2) at […]

Jupiter Might Be Responsible for Our Unusual Solar System, Study Suggests

A montage of Jupiter and its volcanic moon Io, as seen by NASA’s New Horizons spacecraft on its way to Pluto. The results of a new study indicate that the massive gas giant fundamentally altered the evolution of the early Solar System, by destroying any “Super-Earth”-type planets that may have formed, while opening the […]
