Although the parent star is much cooler than the Sun, the planet orbits 13 times closer to the star than Mercury's orbit around the Sun. That means the surface must be a blazing hot 300° C or more, keeping water in its atmosphere in vapour form. But the high pressures in the planet's interior would compress the water so much that it would stay solid even at hundreds of degrees Celsius - the expected temperatures inside the planet...

The team used the Very Large Telescope in Chile to study the supernova 1987A, which lies 168,000 light-years away. The results show the original blast was very powerful and concentrated in one particular direction. Seen in 1987, it was the first supernova visible with the naked eye to have been observed for some 383 years.

Twinkling in the sky is a diamond star of 10 billion trillion trillion carats, astronomers have discovered. The cosmic diamond is a chunk of crystallised carbon, 4,000 km across, some 50 light-years from the Earth in the constellation Centaurus. It's the compressed heart of an old star that was once bright like our Sun but has since faded and shrunk...

There is now even more evidence that life on Earth may have been seeded by material from asteroids or comets. Prior research has shown how amino acids - the building blocks of life - could form elsewhere in the cosmos. These molecules can form in two versions, but life on Earth exclusively uses just one of them. Now an Astrophysical Journal Letters paper shows how conditions around a far-flung star could favour the formation of one type...

Japanese astronomers claim to have found free-floating "planets" which do not seem to orbit a star. Writing in Nature, they say they have found 10 Jupiter-sized objects which they could not connect to any solar system. They also believe such objects could be as common as stars are throughout the Milky Way...

A cataclysmic explosion of a huge star near the edge of the observable Universe may be the most distant single object yet spied by a telescope. Scientists believe the blast, which was detected by Nasa's Swift space observatory, occurred a mere 520 million years after the Big Bang. This means its light has taken a staggering 13.14 billion years to reach Earth...
