Milky Way and Andromeda

Hey everyone, for this week's article I will be talking about the most recent research publication by Simon Mutch and his group of astronomers, of the Swinburne University of Technology in Melbourne. These astronomer's research demonstrates that Milky Way and Andromeda are in transition from being young and star-forming into old and stagnant galaxies. They came up with the conclusion using the color difference between the young and the old galaxies. Instead of being blue or red color, a sign of young and active galaxy, Milky Way and Andromeda are green which is a sign of an old galaxy. Besides not being able to form new stars, the astronomers also said that these galaxies will be unable to produce an active galactic nucleus or AGN, which is brightest radio signals that can be seen across great distances.
