Animal fun fact number two:Polar bear’s fur is transparent and their skin is black!!
HOW COOL IS THAT??
Wait HANNAH YOU SHOULD READ ALI HAZELWOOD’S BOOKS!!
One of her protagonists is obsessed with Marie curie!
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 love a good astronomy theme! i just finished up a minor in astronomy, and my major is in the geology side of space stuff, so if anyone wants to chat more about astronomy let me know! i could probably drum up a few fun facts as well if anyone is interested
here's a fun one: a lot of media gets the words "parsec" and "lightyear" wrong. they are both a unit of measure, with a parsec (pc) being about 3.26 lightyears (ly). the word parsec means the parallax at one arcsecond, which to simplify a more complicated concept, is measuring the wobble of the star nearest to us (besides the sun). one parsec is the distance from Earth to that star, which is Proxima Centauri. a lightyear is the distance light travels in one year. when astronomers and astrophysicists are doing calculations, the are likely to put their numbers in terms of parsecs or kilometers, while the press releases to the general public will often turn those numbers into lightyears, for seemingly no reason.
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
