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.
As we learned in a previous video, there are 100 to 400 billion stars in the Milky Way and more than 100 billion galaxies in the Universe â maybe as many as 500 billion. If you multiply stars by galaxies, at the low end, you get 10 billion billion stars, or 10 sextillion stars in the Universe â a 1 followed by 22 zeros.
