Do thoughts about an endless sky above start bothering you minutes before you should fall asleep? Black holes make you unexplainably anxious? Are extraterrestrials real? As vast and unexplored as space is, there sure are plenty of cool scientific facts to put your mind at rest. And, to save you (and ourselves) from another sleepless night spent wondering about the miracles (or science) of the universe, we've rounded up some of the most important space facts in this fun little article.
From the length of the day on various planets in our solar system to diamond showers and the actual size of heavenly bodies compared to a unit of measurement we all understand - football stadiums - all the basics are covered in our facts about space. After the groundwork comes the more complex questions about gaseous compositions, thermodynamics, and such - no stone unturned in these cool facts about space! And, the further we dig into the core topics of our universe, the more at ease you'll probably start to feel. At least we do desperately hope that these fun facts about space will soothe you and calm you instead of scrambling your thoughts on black holes even further.
Now, jump into your moon boots, and let's explore the universe of cool space facts together! Although presumably, they should be somewhere higher up, the interesting facts are instead a bit further down. Once you are there, rank the bits of info by their unexpectedness and share this article with your friends!

No explanation is given for quite a few of these and the information is questionable.
Got Banned But Now I'm Back 2 years ago
Agreed. I liked that you called out some of the things I questioned, too. I did look up a couple and was surprised. the dung beetle thing? Like how do they KNOW the tiny buggies are looking at THAT? Why not just the stars? Or their inner navigation systems? But there IS a study. Whether it's true or not... I dunno.
