Its actually bigger than that...that was just the "Observable universe"
I can only quote a line from the movie Contact: “If it is just us, it’s an awful waste of space.”
And that’s just the visible Universe.
"observable universe" which as far as we know is trillions smaller than the actual one.
Those are red giant stars that will eventually blow up in supernovas. The bigger the star the faster they burn through their fuel so the shorter their lives before they blow up.
A star with planets is a "system" (as our "Solar" system, our star is called Sol.). Many stars together is usually called a "Galaxy". A number of Galaxies together is a "Cluster". A number of clusters is called a "Super Cluster".
The Sun is actually a star and most of the others are stars just huge but from earth so small and Ceres is a dwarf planet and callisto is a moon of either Saturn or Jupiter and the black thing are black holes and nebula are where stars are born
And people complain about how long it takes to fly from point to point on this tiny little planet in a backwater section of a barely-average sized galaxy.
There are more stars in the known universe than grains of sand on the entire earth. We're very, very, very small, but beautiful.
I do believe there is life out there but I do not think they are more or less advanced then we are, I believe that they are as advanced as we are . Where as , they are as bound to their planet or atmosphere as we are. I do not see how they could be so advanced that they are able to build spaceships that can travel so far across the galaxy and yet as advance as we are can't go as far as Voyager has reached.

"How do we even measure that? Is it just educated guesses?"
“Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space."
“IT’S HUGE...IT’S HUGE!”
That fear you feel is very natural. We all feel it when we first start learning about the universe’s scale and vast emptiness. It goes away over time the more you learn, even as you’re left stunned by new information. Even still, it’s impossible for us to truly conceive the scale of Earth relative to ourselves, let alone the scale of celestial bodies and galaxies.
Humans can never imagine :
I get overwhelmed three times over with videos like these .

You should check out "TIMELAPSE OF THE FUTURE: A Journey to the End of Time (4K)" by Melodysheep. It's a long and sobering video. Even now, 13 billion years after the big bang, time has barely begun to tick on a universal scale.
Fun fact most of these big stars are called “Red Supergiants” and are one stage away from collapsing/exploding. The impact to us would be small but everything around it would be instantly vaporized or absorbed.
