Traces of Ceres' icy crust found at occator crater

Anomalies in the distribution of hydrogen at Occator crater on the dwarf planet Ceres reveal an icy crust, says a new paper led by Tom Prettyman, a Senior Scientist at the Planetary Science Institute. 

Planetary remnants around white dwarf stars

When a star like our sun gets to be old, in another seven billion years or so, it will no longer be able to sustain burning its nuclear fuel. With only about half of its mass remaining it will shrink to a fraction of its ...

Earth-like biospheres on other planets may be rare

A new analysis of known exoplanets has revealed that Earth-like conditions on potentially habitable planets may be much rarer than previously thought. The work focuses on the conditions required for oxygen-based photosynthesis ...

A new super-Earth detected orbiting a red dwarf star

In recent years there has been an exhaustive study of red dwarf stars to find exoplanets in orbit around them. These stars have effective surface temperatures between 2400 and 3700 K (over 2000 degrees cooler than the Sun), ...

Caught speeding: Clocking the fastest-spinning brown dwarfs

Using data from NASA's Spitzer Space Telescope, scientists have identified the three fastest-spinning brown dwarfs ever found. More massive than most planets but not quite heavy enough to ignite like stars, brown dwarfs are ...
