- vitorbaptistaa 1y agoIf Claude is correct, these 0.54 square degrees represent 0.0013% of the full 41,253 square degrees of the sky (4*pi steradians).
- tiagod 1y agoI checked the math and it is correct! So assuming this is a representative sample, there would be 800000/0.000013 ~= 61 billion galaxies in the celestial sphere. According to Wikipedia, "It is estimated that there are between 200 billion to 2 trillion galaxies in the observable universe." Edited: Off by some orders of magnitude.
