Hi .... Stuart with the Show Notes for Series 19 Episode 46:
*First evidence explaining how supermassive black holes are formed Astronomers have discovered evidence for an unusual kind of black hole which would have been born in the very early universe and could have been the seeds for today’s supermassive black holes. While astronomers have a good handle on how stellar mass black holes are formed – mystery has always surrounded their larger counterparts -- the supermassive black holes found at the centre of most if not all galaxies.
Special guest....Aaron Smith from University of Texas, Austin.
*New dwarf planet discovered beyond Neptune It’s not the long sort after mysterious planet 9 – but a new dwarf planet has been discovered orbiting the Sun beyond Neptune.Astronomers spotted the distant frozen world using the Canada-France-Hawaii Telescope on Mauna Kea. The new object -- designated 2015 RR245 is about 700 kilometres in diameter and has one of the largest orbits of any known dwarf planet.
*Rosetta’s mission to end on September 30 The European Space Agency has announced that its Rosetta spacecraft will complete its mission on September 30 performing a controlled descent to the surface of Comet 67P/Churyumov-Gerasimenko.
