Last year it was every 3 months sometimes to the day and then I had about a 5 month period without any but now I have had them 2 months in a row almost to the day. I was writing it in my calander trying to go long enough to get the shot (6 months) that is when I noticed they were occurring at exact times.
By extrapolating these results over the entire sky (which is some 10 million times larger), we were able to figure outâat minimumâthat there were at least 100 billion galaxies in the entire Universe. I even made a video about it.
And so, if you multiply the number of stars in our galaxy by the number of galaxies in the Universe, you get approximately 10 24 stars. Thatâs a 1 followed by twenty-four zeros. Thatâs a septillion stars. But there could be more than that.ccording to astronomers, there are probably more than 170 billion galaxies in the observable Universe, stretching out into a region of space 13.8 billion light-years away from us in all directions.
