The microgravity of space can cause astronauts’ blood to run backwards.
Germany has launched a rocket with yeast on board into space. When the rocket returns the yeast will be used to make beer. Making it effectively space beer.
At the subatomic level, space is never truly empty. It is filled with a writhing, active population of “Virtual Particles” that pop in and out of existence. Physicists call this “quantum foam”. Physicists theorize fluctuations from this field of energy may have given rise to the Universe.
Astronauts returning from space report higher concern with Universalism, Spirituality and references to “values orientated toward the collective good”.
The interstellar travels of Voyager I and II were only possible due to a specific planetary alignment that only occurs every 175 years. The position of the 4 outer planets enabled a slingshot move which greatly increased the crafts speed.
While performing the first space walk in human history, Alexey Leonov’s spacesuit inflated so much he couldn’t get back inside his space capsule. He had to let air out of his suit while still in the vacuum of space and was barely able to fit back through the airlock.
In 1990, the Galileo spacecraft did a search for life on planet Earth during a flyby. It didn’t find any actual life but it did find evidence ‘strongly suggestive of life on Earth’.
Most stars exist in binary or triple star systems. It is hypothesized that up to 85% of stars are gravitationally bound to another star in a multiple star system. Therefore, solitary stars (such as the Sun) are actually not the norm in the universe, but in fact are a rarity.
In 1995, NASA astronomer Bob Williams wanted to point the Hubble telescope at the darkest part of the sky for 100 hours. Critics said it was a waste of valuable time, and he’d have to resign if it came up blank. Instead it revealed over 3,000 galaxies, in an area 1/30th as wide as a full moon.
