This photo doesn’t look like much in this day and age of amazing space photos but this field of view contains 265,000 galaxies. Not stars, GALAXIES.


That is just incomprehensible to me.

What's so incredible to me is that God only picked the third rock orbiting our relatively insignificant Sun to create Mankind.

That is truly mind boggling. Imagine how many stars that would be. 


How many stars are there in the Universe?

"Astronomers estimate there are about 100 thousand million stars in the Milky Way alone."

For the Universe, the galaxies are our small representative volumes, and there are something like 1011 to 1012 stars in our Galaxy, and there are perhaps something like 1011 or 1012 galaxies.

With this simple calculation you get something like 1022 to 1024 stars in the Universe. This is only a rough number, as obviously not all galaxies are the same, just like on a beach the depth of sand will not be the same in different places.

How big is this number.....10 to the 24th power?

10  multiplied by 10,  24 times

10×10×10×10×10×10×10×10×10×10×10×10×10×10×10×10×10×10×10×10×10×10×10×10= 1,000,000,000,000,000,000,000,000


How long would it take to count up to this number?

Hint: The Trump Russian probe would be over before you finish (-:

God and I are not on speaking terms anymore, since She let me fail geometry anyway. <G>
