Astronomers have detected wildly changing temperatures on a super Earth – the first time any atmospheric variability has been observed on a rocky planet outside the solar system – and believe it could be due to huge amounts of volcanic activity, further adding to the mystery of what had been nicknamed the ‘diamond planet’.
An international team of astronomers has found a pulsating, dead star beaming with the energy of about 10 million suns. This is the brightest pulsar – a dense stellar remnant left over from a supernova explosion – ever recorded.
The discovery of water vapour in the atmospheres of three exoplanets includes the most precise measurement of any chemical in a planet outside the solar system, and has major implications for planet formation and the search for water on Earth-like habitable exoplanets in future.
Video of magnetic field lines “slipping reconnection” bring scientists a step closer to predicting when and where large flares will occur.
Latest research on rocky relics suggests a distant planetary system, now past its “death throes”, had very similar water ‘delivery system’ to our own - and consequently the potential to contain habitable exoplanets complete with water
Astronomers have discovered enormous smooth shapes that look like vapour trails in a gigantic galaxy cluster. These ‘arms’ span half a million light years and provide researchers with clues to a billion years of collisions within the “giant cosmic train wreck” of the Coma cluster.
Astronomers working with NASA's Chandra X-ray Observatory have seen the giant black hole Sagittarius A* rejecting its ‘food’ of vast gas clouds as they aren’t sufficiently cool enough for it to swallow.
