The green bean galaxy J2240 (annotated)

This view from the Canada-France-Hawaii Telescope shows a close-up of the sky around a very unusual green object called J224024.1−092748 or J2240. It is a bright example of a new class of objects that have been nicknamed green bean galaxies. Green beans are entire galaxies that are glowing under the intense radiation from the region around a central black hole. J2240 lies in the constellation of Aquarius (The Water Bearer) and its light has taken about 3.7 billion years to reach Earth.
