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.
In fact, there are estimated to be 100 billion stars in 10,000 billion galaxies in the visible universe. This means that there are roughly 1024 stars out there. These spectacular powerhouses come in an array of different colours and sizes â and many make our own Sun look like a mere pipsqueak.
