An international team of astronomers has confirmed the discovery of the most distant supernova ever detected - a huge cosmic explosion that took place 10.5 billion years ago, or three-quarters the age of the Universe itself.
A hole at the heart of a stunning rose-like interstellar cloud has puzzled astronomers for decades. But new research offers an explanation for the discrepancy between the size and age of the Rosetta Nebula's central cavity and that of its central stars.
Researchers have discovered a mechanism that explains the persistence of asymmetrical stellar clusters surrounding supermassive black holes in some galaxies and suggests that during post-galactic merger periods, orbiting stars could be flung into the black hole and destroyed at a rate of one per year.
An international team of astronomers has determined that Centaurus A, a massive elliptical galaxy 13 million light-years from Earth, is accompanied by a number of dwarf satellite galaxies orbiting the main body in a narrow disk.
A dark cloud of cosmic dust snakes across this spectacular wide field image, illuminated by the brilliant light of new stars. This dense cloud is a star-forming region called Lupus 3, where dazzlingly hot stars are born from collapsing masses of gas and dust.
