NASA Study Finds Andromeda Galaxy's Star Formation Declining Over 500 Million Years
A NASA study using Hubble Space Telescope data reveals that the Andromeda Galaxy's star formation has been declining steadily over the past 500 million years, with a sharper decrease in the last 40 million years. Researchers mapped two-thirds of Andromeda's disk, analyzing about 200 million stars, and identified a 'dead zone' near its satellite galaxy M32, suggesting recent interactions disrupted star formation. The galaxy is considered to be transitioning into a less active, 'middle-aged' phase. Findings were published in The Astrophysical Journal.
