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.
Well, if there's between 200 - 400 billion stars in our milky way we can probably get an approximate figure by assuming a few things. Firstly, we need to assume that all galaxies contain the same amount of stars, and we need to assume we know how many galaxies are out there. So lets use the following numbers.
