Could a Paper Plane Thrown from the ISS Survive the Flight?

news.ycombinator.com Universe Today 2025-09-09 09:51:30

Sometimes there are profound questions in life that must be answered, like "What is the meaning of existence?", "Are we alone in the universe?" or "What happens if you throw a paper airplane from the International Space Station?" Luckily, that third one has finally been answered, because of course someone would eventually. A new paper from Maximilien Berthet and Kojiro Suzuki from the University of Tokyo looks at "the dynamics of an origami space plane during Earth atmospheric reentry" – in ot

A Giant Planet and a Small Star Are Shaking Up Conventional Cosmological Theory

wired.com Ritsuko Kawai 2025-09-12 11:00:00

Many of the stars in the Milky Way galaxy are small, dim red dwarfs—stars much smaller than the sun in both size and mass. TOI-6894, located far away from Earth, is one of them. Astronomers previously thought a star like this could not have large planets circulating it, because its mass is only about 20 percent of the sun, meaning its planetary system—generated from materials surrounding the star—would not have contained enough mass to form a giant body like Saturn or Jupiter.

If you run an image search for the word “ARPANET,” you will find lots of maps showing how the government research network expanded steadily across the country throughout the late ’60s and early ’70s. I’m guessing that most people reading or hearing about the ARPANET for the first time encounter one of these maps. Obviously, the maps are interesting—it’s hard to believe that there were once so few networked computers that their locations could all be conveyed with what is really pretty lo-fi car
