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.
How many stars can you see at night? There are billions of stars just in our galaxy and it is estimated that in the visible Universe, there are about 200 â 300 billion large galaxies. It gives a HUGE amount of stars â approximately 10^24. But how many of them can we observe with the naked eye?
