PASADENA, Calif. — Galaxies once thought of as voracious tigers are more like grazing cows, according to a new study using NASA’s Spitzer Space Telescope.
Astronomers have discovered that galaxies in the distant, early universe continuously ingested their star-making fuel over long periods of time. This goes against previous theories that the galaxies devoured their fuel in quick bursts after run-ins with other galaxies.
NASA’s Hubble Finds Rare ‘Blue Straggler’ Stars in Milky Way’s Hub
NASA’s Hubble Space Telescope has found a rare class of oddball stars called blue stragglers in the hub of our Milky Way, the first detected within our galaxy’s bulge.
Blue stragglers are so named because they seemingly lag behind in the aging process, appearing younger than the population from which they formed. While they have been detected in many distant star clusters, and among nearby stars, they never have been seen inside the core of our galaxy.
