Among the four thousand or so stars in the night sky that are visible to the unaided eye, the most distant among them are several thousand light-years away. The light from more distant stars is visible, however, when many of them are associated together in a star cluster or nearby galaxy. It is possible to see, for example, the combined starlight of the Large Magellanic Cloud (about 170,000 light-years away), the 94 Small Magellanic Cloud (about 240,000 light-years away), or even the Andromeda galaxy (about 2.2 million light-years away) with unaided eyes. Using telescopes, we can see starlight from galaxies that are more than thirteen billion light-years away.
