back to article Cosmo study: Middle-aged galaxies are rarer than you'd think

Physicists have created a novel simulation which allows users to watch how the colour of a galaxy changes over time as it evolves. The results will be presented later today at the Royal Astronomical Society National Astronomy Meeting 2016, and are based on a preliminary paper led by researchers at Durham University. The …

    According to this research, our 13.2 billion-year-old home galaxy the Milky Way is close to transitioning to green, but is white at the moment.

    So we'll be all white for a while, then :)

    Speaking of middle aged.

    ...green galaxies probably made up less than ten per cent of all galaxies.

    It ain't easy being green.

    Kind of hard to see "middle-aged galaxies" anyway. They are so far away they all appear young. There could easily be a LOT of middle-aged galaxies. We just can't see them as the light arriving now was emitted in their youth.

      And as our own 13.2 billion year old galaxy is still white it's reasonable to expect that plenty of other galaxies will have yet to have made the transition.
