This is a mosaic image, one of the largest ever taken by Hubble of the Crab Nebula, a 6-light-year-wide expanding remnant of a star’s supernova explosion. Japanese and Chinese astronomers recorded this violent event nearly 1,000 years ago in 1054, as did, almost certainly, Native Americans. Image credit: NASA / ESA / J. Hester / A.

This Hubble shows NGC 1309, a spiral galaxy some 100 million light-years away in the constellation of Eridanus. The color image is made up of observations from Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3) and in the ultraviolet, infrared, and optical parts of the spectrum. Four filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

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.

In the center of the image, the stars cluster to form a bright and dense green candy floss-colored haze, that is the Large Magellanic Cloud. Scattered across the middle of the image are about 50 small yellow crosses, some of them are so close to one another that they almost overlap. SNR J0624-6948 (orange, higher in the image) and SNR J0614-7251 (blue, lower in the image) are seen in the lower left quarter of the image.
