Hubble has spotted an ancient galaxy that shouldn’t exist
This galaxy is so large, so fully-formed, astronomers say it shouldn’t exist at all. It’s called a “grand-design” spiral galaxy, and unlike most galaxies of its kind, this one is old. Like, really, really old. According to a new study conducted by researchers using NASA’s Hubble Telescope, it dates back roughly 10.7-billion years — and that makes it the most ancient spiral galaxy we’ve ever discovered.
"The vast majority of old galaxies look like train wrecks," said UCLA astrophysicist Alice Shapley in a press release. "Our first thought was, why is this one so different, and so beautiful?"

I have literally been waiting for this gifset for all time
grandmoms are precious and must be protected at all costs
i told her i was posting this on tumblr and she said “let me know how many hits i get!!!” so just watch this and make an old woman happy
It is so exceptionally hard to pull off that cartoony look, but this chick like… knocked it out of the park. Perfection.
OH MY GOD THIS COSPLAYER
seriously JUST BROWSE HER GALLERY
Hollywood: “But we can’t make the costumes look like they do in the comic books or cartoons! It’s too unrealistic!”
Hollywood: “It won’t look right!”
Hollywood: “Fans demand realism!”
Me: "YOU SIT ON A THRONE OF LIIIEEESSS!!!!!"
FERNGULLY THOUGH!!! SHE FREAKING DID CRYSTA FROM FERNGULLY!!!
maybe the best vine ever
The guy on the left, since he shows clear disgust with having his picture taken suddenly without permission. The guy on the right has had so little sleep that his grip on reality and emotions has left him
Jesus take the—BUCKY NO
Tim Burton’s Nightmare before Pokemon
I think you mean ‘Time Burton’s Pokémon Dream Land’, I don’t understand how pokémon can be nightmarish.
… Y’see, now, y’see, I’m looking at this, thinking, squares fit together better than circles, so, say, if you wanted a box of donuts, a full box, you could probably fit more square donuts in than circle donuts if the circumference of the circle touched the each of the corners of the square donut.
So you might end up with more donuts.
But then I also think… Does the square or round donut have a greater donut volume? Is the number of donuts better than the entire donut mass as a whole?
A round donut with radius R1 occupies the same space as a square donut with side 2R1. If the center circle of a round donut has a radius R2 and the hole of a square donut has a side 2R2, then the area of a round donut is πR12 - πr22. The area of a square donut would be then 4R12 - 4R22. This doesn’t say much, but in general and throwing numbers, a full box of square donuts has more donut per donut than a full box of round donuts.
The interesting thing is knowing exactly how much more donut per donut we have. Assuming first a small center hole (R2 = R1/4) and replacing in the proper expressions, we have a 27,6% more donut in the square one (Round: 15πR12/16 ≃ 2,94R12, square: 15R12/4 = 3,75R12). Now, assuming a large center hole (R2 = 3R1/4) we have a 27,7% more donut in the square one (Round: 7πR12/16 ≃ 1,37R12, square: 7R12/4 = 1,75R12). This tells us that, approximately, we’ll have a 27% bigger donut if it’s square than if it’s round.
tl;dr: Square donuts have a 27% more donut per donut in the same space as a round one.
Thank you donut side of Tumblr.
This is the highest and best use of conic sections I have ever seen.
I’m pretty sure this donut shop is in my town…
