Hubble Spies Faint Irregular Galaxy
NASA's Hubble Space Telescope has captured an image of the faint dwarf irregular galaxy ESO 490-017. This galaxy is located about 23 million light-years away in the constellation Canis Major and measures approximately 12,000 light-years in diameter. The image reveals the galaxy's low surface brightness, making it appear as a faint swarm of stars against a backdrop of more prominent celestial objects.

Credit: NASA, ESA, R. Tully (University of Hawaii); Image Processing: G. Kober (NASA/Catholic University of America) This NASA Hubble Space Telescope image released on May 27, 2026, features the dwarf irregular galaxy ESO 490-017, roughly 12,000 light-years in diameter and some 23 million light-years away in the constellation Canis Major. The galaxy’s low surface brightness makes it appear as a faint, starry swarm behind brighter foreground stars that are easily recognized by their diffraction spikes.
