Biggest known black hole discovered
Astronomers have confirmed what could be the most massive black hole ever detected – a monster 21 billion times the mas of our Sun -- at the heart of a placid looking galaxy 300 million light years away.  The record breaking supermassive black hole at the centre of the elliptical galaxy NGC 4889 in the Coma cluster, was detected in new images by the Hubble Space telescope.
 
Five-dimensional black hole could 'break' general relativity
Researchers have shown how a bizarrely shaped black hole could cause Einstein's general theory of relativity, a foundation of modern physics, to break down. However, the research also shows such an object could only exist in a universe with five or more dimensions.
 
Pluto's surface is only ten million years old
A new study claims Pluto's heart shaped Sputnik Planum region is only ten million years old -- far younger than the rest of the distant Kuiper Belt dwarf planet. The findings are based on a study of the number of impact craters detected on the frozen surface of Pluto by NASA's New Horizons spacecraft.
 
Immense gas cloud to collide with the Milky Way Galaxy
An immense gas cloud over 11 thousand light years wide is expected to slam into the Milky Way galaxy at over a million kilometres an hour. The cosmic collision which is expected to happen in about 30 million years from now, will spark a flurry of starburst triggering the formation of millions of new stars.
