The drop in temperature from Jupiter’s shadow demolishes its moon Io’s atmosphere, which then rebuilds once the shadow passes.
Scientists have recently discovered repeating radio signals coming from a mysterious source well beyond the Milky Way. While one-off fast radio bursts (FRBs) have been detected in the past, this is the first time multiple signals have been detected coming from the same place in space.
If you fly through an “asteroid belt”, you’re probably not gonna see a single asteroid.
Fifty-five years ago today, astronaut Yuri Gagarin made history, when he got into Soviet Vostok 1 spaceship capsule and launched into space. Yuri Gagarin became the first human in space. Reports praised Gagarin for his perfect flight, but in fact he didn’t pilot the Vostok capsule. Psychologists working with the Soviet Space Program were worried that exposure to weightlessness would impact the pilot’s decision-making faculties. And so, the pilot was effectively locked out of controlling his capsule.
In 1993, the American company Space Marketing Inc. proposed to build a giant advertising billboard in outer space that would appear roughly the same size and brightness as the moon. The project didn’t meet funding and inspired a bill to ban all advertisement in outer space.
Astronauts in the Apollo program reported seeing “streaks” of white light every 3 minutes, even when they closed their eyes.
If an astronaut “loses it” in space, part of the protocol is to restrain them with duck tape.
The Minnesota Vikings are building a stadium that costs more than sending a space probe to Pluto.
The light of galaxies greater than 14.7 billion light years away will never reach us, because those parts of the universe are receding away from us at faster than light speed.
There is a theory that predicts that the universe is a projected 3D illusion created by a 2D surface on the outermost edges of space. Not too different from a hologram.
