This Hubble image shows NGC 2770, a spiral galaxy located in the constellation of Lynx, 83.8 million light-years away. The color image was made from separate exposures taken in the visible and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). It is based on data obtained through four filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This composite image shows thousands of star-forming galaxies in radio light and the MeerKAT radio telescope array in the South African Karoo semidesert. The brightest spots are luminous radio galaxies powered by supermassive black holes. The myriad faint dots are distant star-forming galaxies like our own Milky Way, too faint to have been detected before now. Because radio waves travel at the speed of light, this image is a time machine that samples the star formation history of the Universe. Image credit: SARAO / NRAO / AUI / NSF.

Magnetic fields in the spiral galaxy Messier 77, also known as M77 and NGC 1086, are shown as streamlines over a visible light and X-ray composite image of the galaxy from the NASA/ESA Hubble Space Telescope, NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR), and the Sloan Digital Sky Survey. The magnetic fields align along the entire length of the massive spiral arms of Messier 77, implying that the gravitational forces that created the galaxy’s shape are also compressing the its magnetic field. This supports the leading theory of how the spiral arms are forced into their iconic shape known as ‘density wave theory.’ SOFIA studied the galaxy using far-infrared light (89 microns) to reveal facets of its magnetic fields that previous observations using visible and radio telescopes could not detect.

This composite image shows the surroundings of a supermassive black hole that is triggering star formation across the longest distance ever seen; as hot gas swirls around the black hole, it emits large amounts of X-rays that Chandra detects; the black hole is also the source of radio-wave emission from a jet of high-energy particles -- previously detected by scientists with the VLA -- that stretches about a million light-years.
