The Andromeda Galaxy May Be Getting Bullied by a Smaller Galactic Neighbor, Scientists Find

The Andromeda galaxy may be getting bullied by a smaller galactic neighbor, scientists find

Thanks to the Hubble Space Telescope, astronomers have shed light on a recent chapter in the history of our Milky Way's neighboring galaxy, Andromeda.Using Hubble Space Telescope observations of Andromeda's stars, a research team showed that the spiral galaxy's rate of making new stars has dramatically slowed down in the last 40 million years. And they've found more evidence that one of Andromeda's own neighbors — a smaller galaxy called M32 — m…

Cosmic engines across Andromeda sputtered: Microscopic neighbor triggers long fade

Astronomers 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. While it was previously known that Andromeda experienced a massive burst of star formation approximately 2 billion years ago—likely triggered by cont…

Hubble Finds Andromeda’s Star Formation Is Winding Down

Andromeda is often described as the Milky Way’s larger neighbour and future collision partner. A new study using NASA’s Hubble Space Telescope adds another part to that story: the galaxy has been making new stars more slowly for hundreds of millions of years. The study combines two Hubble surveys that mapped about two-thirds of Andromeda’s […] The post Hubble Finds Andromeda’s Star Formation Has Been Fading for 500 Million Years appeared first o…
