i learned a fun fact about dinosaurs in a class im taking on fossils:
dinosaurs (at least the ones we were discussing) had long, pointy teeth, meaning they couldn't grind up their food with their teeth the way humans do. instead, they would swallow smooth rocks to grind up the food in their stomachs. this would work alongside their respiratory system, meaning breathing helped move the rocks, which in turn helped to extract the nutrients from their food



i can do another astronomy fun fact for today! (it'll be more planetary science than astronomy, but i think im the only one who cares about that distinction)
the perseverance mars rover (the newest rover) landed in the Jezero crater with the goal of learning about the water systems that used to be on mars and any potential life. this was the spot chosen because you can see river channels running into that crater, and more importantly there is a delta very close to the landing site. just from deltas here on earth, we know that you can find a very good deposit of sediments in layers over time that were transported down from areas of higher elevation by water. we are hoping to return samples from that deposit on mars, which has the best chance at telling us about any potential for previous or current microbial life on mars
