Reply to comment by Solar-G2V in the sun in hydrogen alpha by Solar-G2V

it is very hard to position a telescope by hand to the eyepiece. When I tried it I saw more sunspots with naked eye than my phone camera could see. Do you think the sensors are good enough to capture all details you see?

That number (10^39) is about a hundred million billion too high - give or take a factor of 100.

Still, a reasonable estimate of stars (and, given an average of one planet per star, about the same number of planets) is about 10^22. It is almost inconceivable that earth is the only place with life.

Also, the first life could not have formed immediately after the Big Bang, because the only elements then were hydrogen and helium. These two formed the first stars, and after a few hundred million years, the larger ones could have exploded, forging the other elements that are necessary for life.

100%. People only think of how vast space is but forget to consider how old the universe is. So not only are there 1000000000000000000000000000000000000000 stars out there, all with the potential for life there are over 13 billions of years for life to have come and gone from any given one.
