Hubble Spies Faint Irregular Galaxy ESO 490-017
NASA’s Hubble Space Telescope captured a new image of the faint dwarf irregular galaxy ESO 490‑017, which spans roughly 12,000 light‑years and lies about 23 million light‑years away in Canis Major. The galaxy’s low surface brightness makes it appear as a diffuse star field behind brighter foreground stars. The observation was part of a program mapping the motion of galaxies and clusters, known as cosmic flow, by measuring distances with red‑giant standard candles. The resulting data also enriches a legacy archive of stellar populations in nearby dwarf galaxies.
