The more we know, the more we know we don’t know, y’know?
Apparently, a census of the visible universe has been collated, tabulated, and our earlier estimates of the number of galaxies was off. A bit.
The observable universe—that is, the part of the universe that’s visible to us on Earth—contains 10 to 20 times as many galaxies than previous estimates. That raises the total to somewhere between one and two trillion galaxies, which is up from the previous best estimate of 100 billion galaxies. Consequently, this means we also have to update the number of 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).
Here’s a now under-dense image of the galaxies (Southern skies btw) mapped out prior to this new estimate:
