A stellar circle of life near Cygnus X-3
A discovery that provides a new way to study how stars form has been captured in a new portrait from NASA’s Chandra X-ray Observatory and the Smithsonian’s Submillimetre Array (SMA). A cloud that is giving birth to stars has been observed to reflect X-rays from Cygnus X-3, a source of X-rays produced by a system where a massive star is slowly being eaten by its companion black hole or neutron star.
Starvation diet for supermassive black hole dims brilliant galaxy
Astronomers may have solved the mystery of the peculiar volatile behaviour of a supermassive black hole at the centre of a galaxy known as Markarian 1018 some 590 million light-years away. Combined data from NASA’s Chandra X-ray Observatory and other observatories suggest that the black hole is no longer being fed enough fuel to make its surroundings shine brightly.
Mysterious flaring X-ray objects discovered in nearby galaxies
Astronomers have found a pair of extraordinary cosmic objects that dramatically burst in X-rays, flaring up to become about a hundred times brighter in less than a minute, before returning to original X-ray levels after about an hour. This discovery may represent a new class of explosive events found in space.
