A supernova exploded. It then appeared 4 times in 4 places in the sky. This seems to prove gravitational lensing happens... in case anybody doubted it, it now seems a lot more proven. The relative time delays are of order 10-100 years and more images of it will probably come to those who wait another 10-100 years. http://www.eurekalert.org/pub_releases/2015-03/uoc--dss022515.php
