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.
