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.
Kornreich used a very rough estimate of 10 trillion galaxies in the universe. Multiplying that by the Milky Way's estimated 100 billion stars results in a large number indeed: 100 octillion stars, or 100,000,000,000,000,000,000,000,000,000 stars, or a 1 with 29 zeros after it.
