Australian astronomers believe they are seeing the creation of a black hole at the centre of a star. This is the first time that such an event has been observed. Last month the BeppoSAX satellite spotted a burst of gamma rays from a suspected supernova explosion in the galaxy ESO 184-82. Ground-based observations by telescopes in Australia indicate that the object is becoming brighter at gamma, visible and radio wavelengths, unlike all other gamma-ray bursts. The astronomers believe that the burst came from the sudden collapse of matter into a black hole.
