Cosmic engines across Andromeda sputtered: Microscopic neighbor triggers long fadeAstronomers using data from the Hubble Space Telescope have identified a significant decline in star formation rates within the Andromeda galaxy over the last 40 million years. The research suggests that a miniature satellite galaxy, M32, may be responsible for slowing these evolutionary processes. Researchers collected data on 200 million stars by dividing the region into a grid of squares, each with a side of 300 light-years. The Influence of M32The decline in star formation is not uniform; one side of Andromeda is "cooling" faster than the other. Is M32 part of the Andromeda galaxy?
