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.

From a great distance, our Milky Way Galaxy would look like a thin disk of stars that orbits once every few hundred million years around its central region, where hundreds of billions of stars provide the gravitational ‘glue’ to hold it all together. But this pull of gravity is much weaker in the Galaxy’s far outer disk. There, the hydrogen atoms making up most of the Milky Way’s gas disk are no longer confined to a thin plane, instead they give the disk an S-like, or warped, appearance. Image credit: Xiaodian Chen.

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.
