This stunning image of NASA/ ESA Hubble Space Telescope features the spiral galaxy NGC 5643 in the constellation of Lupus (The Wolf). Looking so good isn’t easy; Thirty different exposures, for a total of 9 hours of observation, together with Hubble’s high resolution and clarity, were required to produce an image of such a high level of detail and beauty.

NGC 5643 is located about 60 million light years from Earth and was the host of a recent supernova event (not visible in this latest image). This supernova (2017cbv) was a specific type in which a White dwarf it steals so much mass from a companion star that it becomes unstable and explodes. The explosion releases significant amounts of energy and illuminates that part of the galaxy.

The observation was proposed by Adam Riess, Nobel Prize in Physics 2011 for his contributions to the discovery of the acceleration of the expansion of the Universe, together with Saul Perlmutter and Brian Schmidt.
