Red Galaxies Aren't Necessarily Dead Galaxies

[Binary_Bark]

The human perception of stars is that they are largely unchanging although of course in reality stars and their host galaxies do change over time, just very VERY slowly. When galaxies deplete their star forming materials, they traditionally become redder as short lived stars die while long lived dwarf stars persist for trillions of years. However, recent research challenges this understanding, suggesting some red galaxies continue forming stars—specifically low-mass stars that are inherently red throughout their existence. This discovery indicates galactic evolution may be more complex than previously believed.
