space is pretty cool, but when you really think about the vastness of it it’s kinda terrifying
there are stars and solar systems that are not contained into a galaxy, imagine living there, it’d be scary, we have a galaxy to call home, but those civilizations? they have nothing, only a star and their planets, billions of light years away from any other star
Astronomy may be my favorite subject in science, it’s just so interesting for all the activities that occur in space that we will never witness in our lives.
Simply contemplating the fact that our galaxy, which spans 1,000,000,000,000,000 kilometers across, is still dwarfed by the local group, which it is a part of, which in turn is sidelined by the enormity of super clusters which in turn is rendered obsolete by the complete and utter vastness of what is an ever-expanding universe is enough to melt the brain of any mortal.
Scientists have found bacteria from space. You guys realize this technically means aliens are real right? It’s a bit of a stretch, but hey, Bacteria counts as life.
I love the fact that by only looking at the light that the star emits we can be sure what temperature it is, the size it is, the age, the amount of light it emits, and if its able to support life…all that just by analysing its light.
