Explanation: Where did this big ball of stars come from? Palomar 6 is one of about 200 globular clusters of stars that survive in our Milky Way Galaxy. These spherical star-balls are older than our Sun as well as older than most stars that orbit in our galaxy's disk. Palomar 6 itself is estimated to be about 12.5 billion years old, so old that it is close to -- and so constrains -- the age of the entire universe. Containing about 500,000 stars, Palomar 6 lies about 25,000 light years away, but not very far from our galaxy's center. At that distance, this sharp image from the Hubble Space Telescope spans about 15 light-years. After much study including images from Hubble, a leading origin hypothesis is that Palomar 6 was created -- and survives today -- in the central bulge of stars that surround the Milky Way's center, not in the distant galactic halo where most other globular clusters are now found.

Wow that is a lot of stars. I remember as a kid being told that there were more stars out there than grains of sand on earth. I guess that could be true, but I only see a small handful of sand in this picture.

Captivating, as usual. Take time and give it much study.

So that's how Biden got 80 million votes.

Biden got 80 million votes

Trump got about 75 million votes

That totals 155 million votes but since there are only 135 million eligible voters, that means about 20 million grains of sand had to vote for the Biden, the senile old fool. With the stars being 25 million light years away, we can safely rule them out as their votes won't be here for another-25 million years even if they voted over the speed of light cosmic internet.

I knew there had to be a simple explanation.

Beautiful!

And if you were located in a planet somewhere on the edges of this cluster in a place where you did not melt away with the solar winds of 100,000 stars, the light from those stars shining on your planet would never go out and there would be no night!

A lot of factors go into how many stars one can see but if one has good vision of a young to middle aged person and its a clear dark night the number is somewhere around 2 to 4 thousand. That’s for half the celestial sphere. Double it for the half you don’t see. The estimate of how many stars are in our own galaxy is rather wide from 100 to 400 billion. The estimate of the number of galaxies in our universe is 100 to 200 billion. Using the lower estimates for both you get 100 billion squared for a very rough guess of the number of stars in the known universe. Probably more than the grains of sand on earth. :)
