The mysterious train became the main sight of St. Louis, a little village in the Canadian province of Saskatchewan. There are just around 400 people living there and hundreds visit it to see the St. Louis light. It was featured in books and online, and was on TV shows like Unsolved Mysteries.

And guys, if you've always wanted to know how many stars are in our galaxy, there's good news for you. The Gaia Mission has been working on making a 3D model of our galaxy and getting a more accurate count of the number of stars in it. They thought it was 1 billion, but that estimate could be up to 400 or even 700 billion stars!

When will our universe end? Many astronomers agree that this might happen some 2.8 to 22 billion years from now. The thing is that if the Universe is expanding (and it is), it means it was born from a much more compact state. Like Rhode Island. And if it does have a beginning, it's likely to come to an end too! But how exactly will it happen?

By the way, does our Universe have an edge? What happened before the Big Bang? How come we know next to nothing about dark matter and dark energy? What if there are no black holes? Will we ever find the answers to the most intriguing questions about the Universe? Let's talk about some cosmic mysteries that scientists still hope to solve.
