Now You See it, Now You Don't: Massive Star Goes Out With a Whimper Instead of a Bang
This pair of visible-light and near-infrared Hubble Space Telescope photos shows the giant star N6946-BH1 before and after it vanished out of sight by imploding to form a black hole. The left image shows the 25 solar mass 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 infrared light has been detected from where the star used to be. This radiation probably comes from debris falling onto a black hole. The black hole is located 22 million light-years away in the spiral galaxy NGC 6946.

| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the WFPC2 and WFC3/UVIS instruments on the Hubble Space Telescope. Two filters in each instrument were used to sample narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are cyan: F606W and orange: F814W. |
