Yellow color galaxies

• by Veegee

  Are the yellow colored galaxy shots, true color? I mean, are these old galaxy's who have no or little new star formation and
  are full of old yellow stars now? Almost all I have seen seem to be elliptical galaxies.

  Aaaahhhhh - they are both simulated galaxies so they will tend to share similar 'yellow' characteristics. With these galaxies, just try to classify them as if it was a real galaxy.

  what are simulated galaxies? I saw that label on one galaxy when I went into the detail page--I see lots of these color galaxies
