This pair of visible-light and near-infrared Hubble photos shows N6946-BH1 before and after it vanished out of sight by imploding to form a black hole. The left image shows the star as it looked in 2007. In 2009, the star shot up in brightness to become over 1 million times more luminous than our Sun for several months. But then it seemed to vanish, as seen in the right panel image from 2015. A small amount of IR light has been detected from where the star used to be. This radiation probably comes from debris falling onto a black hole. Image credit: NASA / ESA / C. Kochanek, Ohio State University.

This global view of Io was obtained by NASA’s Galileo spacecraft on 19 September 1997 at a range of more than 500,000 km (310,000 miles). In this image, deposits of sulfur dioxide frost appear in white and grey hues while yellowish and brownish hues are probably due to other sulfurous materials. Bright red materials and ‘black’ spots with low brightness mark areas of recent volcanic activity and are usually associated with high temperatures and surface changes.
