VLT Captures Image of Double-Detonation Supernova Remnant

This image, taken with the Multi-Unit Spectroscopic Explorer (MUSE) instrument on ESO’s Very Large Telescope (VLT), shows the supernova remnant SNR 0509-67.5 -- the expanding remains of a star that exploded hundreds of years ago in a double-detonation. Calcium is shown in blue, and it is arranged in two concentric shells. These two layers indicate that the star exploded with a double-detonation. Image credit: ESO / Das et al. / Noll et al.

Astronomers using ESO’s Very Large Telescope (VLT) have imaged SNR 0509-67.5, a very young (300-350 years old) remnant of Type Ia supernova, and spotted patterns that confirm its star suffered a pair of explosive blasts. This image, taken with the Multi-Unit Spectroscopic Explorer (MUSE) instrument on ESO’s Very Large Telescope (VLT), shows the supernova remnant SNR 0509-67.5 — the expanding remains of a star that exploded hundreds of years...

This Hubble image shows GN 04.32.8, a reflection nebula some 480 light-years away in the constellation of Taurus. The color composite was assembled from images taken in visible and near-infrared light. It is based on data obtained through two filters. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / G. Duchêne.
