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.
When you see the sky in microwaves, it does indeed glow in all directions. Thatâs the Cosmic Microwave Background Radiation, shining behind all those galaxies. It turns out the Universe has 10 times more galaxies than previously estimated â 2 trillion galaxies. Not 10 times the stars or mass, those numbers have stayed the same. And, once James Webb launches, those numbers will be fine-tuned again to be even more precise. 1.5 trillion? 3.4 trillion?
