Discovery of the best targets yet in the search for life beyond our solar system
Astronomers have discovered three planets with sizes and temperatures similar to Earth -- and which they are now describing as the best targets found so far in the search for life beyond our solar system. The planetary trio were found orbiting an ultra-cool dwarf star about forty light years from Earth in the constellation of Aquarius the water carrier.
Monster supermassive black hole forms out of galactic collision
A monster black hole almost 4 billion times the mass of the Sun has been discovered forming out of a mammoth collision involving three merging spiral galaxies. The new findings are providing scientists with fresh insights into galactic evolution and the growth of supermassive black holes.
Nearby massive star explosion equaled detonation of 100 million Suns
Astronomers have discovered that a giant star in a nearby galaxy that went supernova 30 million years ago -- exploded with the power of 100 million Sun’s – making it one of the most powerful explosions in our cosmic neighborhood in recent years. The mega blast of supernova 2013ej in the spiral galaxy M74 in the constellation Pisces in 2013 blew stellar material out from the star at ten thousand kilometres per second -- equivalent to 36 million kilometres an hour.
