A way of using variable stars—stars that changed their light output in a repeating cycle—allowed astronomers to determine distances to star groups ... called the Andromeda Nebula (after ...

Weisz continues: “Andromeda looks like a transitional type of galaxy that’s between a star-forming spiral and a sort of elliptical galaxy dominated by aging red stars. “We can tell it’s ...

Andromeda seems to be more highly populated with younger stars and unusual features like coherent streams of stars, say researchers. This implies it has a more active recent star-formation and ...

It is so detailed that astronomers can use it to piece together Andromeda's history and past mergers with other galaxies. Astronomers also took closeup images of V1, the star that Hubble saw ...

Now turn 90º and go upwards past one bright-is star, then another. The Andromeda Galaxy is just above it. Here’s a skychart showing how to find the Andromeda Galaxy once you’re in the right ...

Predictions are uncertain, but the solar system may be pushed farther from the galactic core or even ejected entirely from ...

Observations show Andromeda has a more active star formation history than the Milky Way, potentially due to a past galactic collision. NASA recently released images of the Andromeda galaxy ...

This Hubble image of a crowded star field in the disk of the Andromeda galaxy shows that stars of different ages can be distinguished from one another on basis of temperature (as indicated by ...

Dots show locations of stars in the spectroscopic survey superimposed on an image of the Andromeda galaxy (M31). Dots are color coded according to their velocity relative to the Milky Way ...

Scientists believe Andromeda's unique features are due to its merger history and ongoing star formation. Future telescopes will offer even sharper insights. Image source: ESA For more than a ...
