Trillions and Trillions and Trillions of Stars

photo of a cluster of galaxies

This is a photo of a tiny tiny snippet of the universe, taken by the Hubble Space Telescope. Every object you see in the photo is a staggeringly massive galaxy that contains hundreds of billions of stars along with all sort of other things.

Our own galaxy, the Milky Way, is well over one hundred thousand light years across. We only see a pitiful portion of it. Although it contains several hundred billion stars in its expanse, we can only see a fraction of a fraction of them.

And even that doesn’t fully capture the essence of a galaxy, which also has planets, gas, dust, dark matter, and more. Galaxies are colossal objects, their true nature only becoming apparent to us a century ago.

I know I’ve posted photos like this before, but every time I see something like this, my mind boggles anew at the sheer scale and magnitude of it all and I just have to share it.

P.S. And Earth contains the only sentient life in the entire universe? Lol.
