Days like today I’m glad Earths ni a thinly populated section of the galaxy. ;)

Hubble can see galaxies that are many billions of light years away. Individual stars, however, can only be seen by Hubble in galaxies that are much closer, as in the case of M74, 30 million light years away.

I go into the details at much greater length in my book on Hubble, The Universe in a Mirror.
