This is one of the highest-resolution images ever taken of the solar corona, or outer atmosphere. It was captured by NASA's High Resolution Coronal Imager (Hi-C) in the ultraviolet wavelength of 19.3 nanometers. Hi-C showed that the Sun is dynamic, with magnetic fields constantly warping, twisting, and colliding in bursts of energy. Added together, those …

This image of NGC 1277 was taken with Hubble Space Telescope. This small, flattened galaxy contains one of the most massive central black holes ever found. At 17 billion solar masses, the black hole weighs an extraordinary 14% of the total galaxy mass. [NASA/ESA/Andrew C. Fabian] 28 November 2012 - Mcdonald Observatory news Fort Davis, …
Abell-399-401 The Planck satellite has discovered a bridge of hot gas that connects galaxy clusters Abell 399 (lower center) and Abell 401 (top left). The galaxy pair is located about a billion light-years from Earth, and the gas bridge extends approximately 10 million light-years between them. The image shows the two galaxy clusters as seen …
