Astronomers have completed the most accurate census of galaxies in the observable universe to date. It turns out after running through the latest data from Hubble and other observatories that it contains 10 to 20 times as many galaxies than we thought.
That means we have somewhere between one and two trillion galaxies. Prior estimates sat at about 100 billion galaxies. It also means there are more stars in the observable universe, which now numbers around 700 sextillion (that’s a 7 with 23 zeros behind it, or 700 thousand billion billion).
