    The Universe is full of stars!

    By extrapolating some numbers based on local measurements, we can guess there are about 1e12-1e13 galaxies just in the observable part of our Universe, for a total of at least~1e24 stars.

    When did the Universe form them? How well do we know?

    Here is an #AstrophysicsFactlet about this.
