The Star Spot

Feature Guest: Xinyu Dai Last month astronomers announced the first ever discovery of extrasolar planets… in another galaxy! We’ve already confirmed almost 4000 planets beyond our solar system, but these have all been in a single galaxy, the Milky Way. But then last month a serendipitous discovery opened the door to a galaxy 3.8 billion light years away and it turns out it’s home to thousands upon thousands of planets. Today we're joined here at The Star Spot by co-discoverer Xinyu Dai to describe the unplanned discovery and whether this is the beginning of a new era in extrasolar extragalactic planetary astronomy. Current in Space The Andromeda Galaxy has tried hard to hide its past, but Dave exposes its dirty secrets. Then Maya numbers our minds with the discovery of the most distant supernova yet. And when psychologists studied the likely ramifications of first contact Tony found the results surprising.
