NASA's Hubble Shows Star Formation in Andromeda Galaxy Winding Down - NASA Science
A study using NASA’s Hubble Space Telescope found that star formation in the Andromeda galaxy has declined over the past 500 million years.
Why it matters
Studying Andromeda helps astronomers better understand the history and evolution of galaxies like our own Milky Way.
The details
- Current star formation is about one-fifth the mass of our Sun per year.
- Much of the decline occurs in a ring 32,000 light-years from the center.
- Interaction with satellite galaxy M32 may have reduced star formation 60 million years ago.
