✦AI Summary
Astronomers using Hubble Space Telescope data have mapped star formation in the Andromeda Galaxy, revealing a decline in activity. The findings suggest the galaxy is transitioning into a 'middle-aged' quiescent state.
Astronomers have used data collected by the Hubble Space Telescope to piece together the clearest yet map of star formation across most of the Andromeda Galaxy over the last 500 million years. The Andromeda is 2-2.5-times wider than the Milky Way, and the two galaxies have a coin-toss’s chance of colliding within the next 10 billion years.
