http://www.bbc.co.uk/news/science-environment-27118405 An exceptionally bright supernova that baffled scientists has been explained. It is so luminous because a galaxy sitting in front amplifies its light - making it appear 100 billion times more dazzling than our Sun. This cosmic magnifying glass lay hidden between Earth and the supernova - and has now been detected with a telescope in Hawaii. The discovery, reported in the journal Science, settles an important controversy in the field of astronomy. Interesting discovery. I'd heard about gravitational lenses before, but I wasn't aware of any objects that looked brighter than normal because of them. I wonder whether there are any other objects like this? |

That's actually really cool. I'd never heard about something of this nature happening before, so it's interesting. How long did it take for this to be discovered? Because I thought I heard about this Supernova quite some time ago...unless I'm thinking of something else. |

The supernova itself was discovered in 2010, and they weren't sure how to explain its brightness. Someone came up with the idea that it might be gravitational lensing by a large object - but it's taken a while for them to find any evidence of the large object in question. |
