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. Kirshner, Harvard-Smithsonian Center for Astrophysics and Gordon and Betty Moore Foundation / P. Challis, Harvard-Smithsonian Center for Astrophysics.

NGC 5907 X-1 is in the spiral galaxy NGC 5907, which is also known as the Knife Edge Galaxy or Splinter Galaxy. This image comprises X-ray emission data (blue/white) from ESA’s XMM-Newton space telescope and NASA’s Chandra X-ray observatory, and optical data from the Sloan Digital Sky Survey. The inset shows the X-ray pulsation of the spinning neutron star, which has a period of 1.13 sec, as determined by XMM-Newton’s European Photon Imaging Camera.

NASA’s Fermi telescope has detected a gamma-ray excess (shown in yellow-white) at the center of the Andromeda galaxy that’s similar to a signature Fermi previously detected at the center of our own Milky Way Galaxy. Scientists think the signal could be produced by a variety of processes, including a population of pulsars or even dark matter.

Astronomers combined data from ALMA’s 7- and 12-m antennas to produce the sharpest possible image of RX J1347.5–1145, the center of which shows up here in the dark ‘hole’ in the ALMA observations. The energy distribution of the CMB photons shifts and appears as a temperature decrease at the wavelength observed by ALMA, hence a dark patch is observed in this image at the location of the cluster. The optical image of RX J1347.5–1145 was taken with Hubble. Image credit: NASA / ESA / Hubble / T. Kitayama, Toho University / ALMA.
