Oct 19, 2023 · Greek astronomer Aristotle suggested that nature abhors a vacuum—a theory that later became known as horror vacui. Although Atomism led to the rejection of this suggestion, it wasn’t until the 1600s that the theory of no oxygen being present in space could be proved using scientific evidence.

Dec 12, 2018 · On 12 April 1961, Russian cosmonaut Yuri Gagarin became the first human to go into space when he orbited the Earth in the Vostok 1 spacecraft. Since then more than 500 people have blasted out of the Earth’s atmosphere, with over 230 of them going to visit the International Space Station (ISS).
Jun 9, 2015 · But inside the International Space Station (ISS), the American astronauts and Russian cosmonauts do breathe air almost identical to the stuff we breathe down here on planet Earth - same pressure and about 80 per cent nitrogen and 20 per cent oxygen. But from where do they get their oxygen?
May 5, 2015 · You breathe it every minute, but there's hardly any molecular oxygen—otherwise known as O 2 —in space. In 1998, NASA even launched a satellite that was supposed to find lots of molecular oxygen but never did—except when scientists, worried that the instrument was faulty, aimed it at Earth.
Jul 16, 2019 · As Jules Bergman reported for ABC News, in January 1967, Astronauts Gus Grissom, Ed White and Roger Chaffee died in a fire, on the launch pad, in pre-flight testing aboard Apollo 1. "An electrical spark apparently shot out and ignited the 100% oxygen in the cabin that they were breathing as in a real space flight," Bergman said.
Because the earliest bacteria appear fully formed in the fossil record, even respected scientists have not ruled out the possibility that they might have been seeded by comets from outer space . The earliest phototrophic anaerobes likely lived in shallow seas or tidal pools, utilizing sunlight to oxidize hydrogen sulfide, nitric oxide, nitrate ...
