This VLT image shows the spiral galaxy NGC 1055. This large galaxy appears to lack the whirling arms characteristic of a spiral, as it is seen edge-on; however, it displays odd twists in its structure that were probably caused by an interaction with a large neighboring galaxy, Messier 77. The VLT observed NGC 1055 with the FOcal Reducer and low dispersion Spectrograph 2 (FORS2) instrument using visible-light filters. Image credit: ESO.

This Hubble image shows the remnant of SN 1987A within the Large Magellanic Cloud, a satellite galaxy of the Milky Way. The image was taken by Hubble’s Wide Field Camera 3 (WFC3) in January 2017. SN 1987A is located in the center of the image amidst a backdrop of stars. The bright ring around the central region of the exploded star is composed of material ejected by the star about 20,000 years before the actual explosion took place. The supernova is surrounded by gaseous clouds. The clouds’ red color represents the glow of hydrogen gas. The colors of the foreground and background stars were added from observations taken by Hubble’s Wide Field Planetary Camera 2 (WFPC2). Image credit: NASA / ESA / R.

This enhanced color composite image, made with data from NASA’s Dawn spacecraft, shows the area around Ernutet crater, which is about 32 miles (52 km) in diameter and is located in the northern hemisphere. The bright red portions appear redder with respect to the rest of Ceres. In the new study, planetary researchers found that these red areas around Ernutet are associated with evidence of organic material. Images taken using blue (440 nm), green (750 nm) and infrared (960 nm) spectral filters were combined to create the view. Image credit: NASA / JPL-Caltech / UCLA / MPS / DLR / IDA.
