Planet appears to have water-restricted environment
ESO's HARPS instrument finds Earth-mass exoplanet around Ross 128
Magnetospheres deflect high-energy, charged particles that are spewed out by the Sun and protect the planets' surfaces from harmful radiation
An aerospace engineer has built a machine to make water and oxygen from the lunar regolith, powered by solar energy
New work will help astronomers allocate scarce observing time to the most promising candidates for habitability
Space radiation is quite different and more dangerous than radiation on Earth
Planets grow by a process of accretion—a gradual accumulation of additional material—in which they collisionally combine with their neighbors
The mission has told us a great deal about the unique and unexpected chemistry of Saturn's moon Titan, and it has changed the way we think about our own planet and the entire solar system
In a recent study, calculated water loss rates as well as geophysical water release rates favor the idea that the outermost, more massive planets retain their water
