At least. The total number comes in at about 2 trillion of them. Now, let me be clear. This doesn’t meant the Universe is 10 times bigger than we thought, or there are 10 times as many stars. I’ll explain—I mean, duh, it’s what I do—but to cut to the chase, what they found is that there are lots of teeny, faint galaxies very far away that have gone undetected.
