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.
