HD 113766
(Preview)
An Earth-like planet is likely forming 424 light-years away in a star system called HD 113766, say astronomers using NASA's Spitzer Space Telescope. Scientists have discovered a huge belt of warm dust enough to build a Mars-size planet or larger swirling around a distant star that is just slightly...

(Preview)
A study of supernova remnants – material blown out into space during death throes of giant stars – has shown that a bubble of gas enveloping our Solar System is being shoved backwards by the debris of another, more recent, supernova.
Over the last few million years, several stars have exploded wi...
