Superluminous supernova marks the death of a star at cosmic high noon
The death of a massive star in a distant galaxy 10 billion years ago created a rare superluminous supernova that astronomers say is one of the most distant ever discovered. The brilliant explosion, more than three times as bright as the 100 billion stars of our Milky Way galaxy combined, occurred about 3.5 billion years after... More

Spiral arms allow school children to weigh black holes
Astronomers from Swinburne University of Technology, Australia, and the University of Minnesota Duluth, USA, have provided a way for armchair astronomers, and even primary school children, to merely look at a spiral galaxy and estimate the mass of its hidden, central black hole. The research was supported by the Australian... More

Cosmic “dust factory” reveals clues to how stars are born
A group of scientists led by researchers at Cardiff University have discovered a rich inventory of molecules at the centre of an exploded star for the very first time. The findings are published today in the journal Monthly Notices of the Royal Astronomical Society. This artist's illustration of Supernova 1987A reveals the... More

Milky Way could have 100 billion brown dwarfs
Our galaxy could have 100 billion brown dwarfs or more, according to work by an international team of astronomers, led by Koraljka Muzic from the University of Lisbon and Aleks Scholz from the University of St Andrews. On Thursday 6 July Scholz will present their survey of dense star clusters, where brown dwarfs are abundant,... More

Re-Making Planets after Star-Death
Astronomers Dr Jane Greaves, of the University of Cardiff, and Dr Wayne Holland, of the UK Astronomy Technology Centre in Edinburgh, may have found an answer to the 25-year-old mystery of how planets form in the aftermath of a supernova explosion. The two researchers will present their work on Thursday 6 July at the National... More

First look at gravitational dance that drives stellar formation
Swirling motions in clouds of cold, dense gas have given, for the first time, an active insight into how gravity creates the compact cores from which stars form in the interstellar medium. The results will be presented today, Thursday 6 July, by Gwen Williams at the National Astronomy Meeting at the University of... More

Fastest stars in the Milky Way are ‘runaways’ from another galaxy
A group of astronomers have shown that the fastest-moving stars in our galaxy – which are travelling so fast that they can escape the Milky Way – are in fact runaways from a much smaller galaxy in orbit around our own.   The researchers, from the University of Cambridge, used data from the Sloan Digital Sky Survey...

"Little Cub" gives astronomers rare chance to see galaxy demise
A primitive galaxy that could provide clues about the early Universe has been spotted by astronomers as it begins to be consumed by a gigantic neighbouring galaxy. The Little Cub galaxy – so called because it sits in the Ursa Major or Great Bear constellation – is being stripped of the gas needed to continue forming...
