There is so much space debris in earth’s atmosphere that in future it may just become dangerous to leave earth and we may get trapped in our own garbage.
Neutron stars can spin at a rate of 600 rotations per second.
The solar system is moving through the Local Interstellar Cloud, proving that you are never in the same spot more than once on a cosmic scale.
Apollo Mission astronauts have nearly five times higher mortality from cardiovascular disease than other astronauts due to exposure to deep-space radiation.
The left most pillar of the famous Pillars of Creation, is actually 4 Light Years tall. That is equal to roughly 37,844,000,000,000 Kilometers.
In 1963, at the height of the Cold War, the US military launched a ring of 480million needles into orbit around the earth. It was hoped they would more reliably bounce radio signals back to earth in case the Soviets cut through undersea cables. Multiple clumps of these needles are still up there.
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.
