‘Hand of God,’ this object is called a pulsar wind nebula. It's powered by the leftover, dense core of a star that blew up in a SN explosion. The stellar corpse, called PSR B1509-58, is a pulsar. NASA's NuSTAR spacecraft has imaged the struc-ture in high-energy X-rays for the 1st time: blue:: lower energy X-Ray light previously detected by Chandra: green & red | NASA:
The cluster is surrounded by clouds of interstellar gas and dust—the raw material for new star formation. The nebula, located 20,000 light-years away in the constellation Carina, contains a central cluster of huge, hot stars, called NGC 3603. CREDIT: NASA, ESA, R., F. Paresce, E.

#NGC474 is an elliptical galaxy in the constellation Pisces. This large galaxy is known to possess tidal tails, although their origins remain unknown. These tidal tails may be related to debris left over from absorbing numerous small galaxies in the past billion years.
