Astronaut Scott Kelly will become even younger than his twin elder brother (also an astronaut) Mark Kelly (born 6 minutes before Scott), by three milliseconds after the completion of his one year mission on the ISS.
In 2008 there was a gamma ray burst, a violent cosmic explosion, 7.5 billion light years away, which is halfway across the visible universe, which could have been seen with a naked eye from the surface of the Earth. Anyone who saw it was looking billions of years into the past with their eyes.
There are “lone planets” that roam endlessly through space without ever going into orbit. They are actually predicted to be more common than stars.
Since 2001 astronomers have detected 11 high frequency radio signals, which share an underlying mathematical pattern that defies explanation as naturally occuring phenomena.
The only deaths to have occurred in space thus far were in 1971, when 3 Soviet cosmonauts fell victim to a catastrophic decompression of their return module. The module executed a perfect automated landing, without a living person on-board.
The Andromeda galaxy is heading towards us at 250,000 miles per hour. We are expected to collide with it in 4 billion years.
There exists a planet between Mars and Jupiter known as Ceres. It’s a dwarf planet, like Pluto, and may contain water and an atmosphere.
Something astoundingly huge in a distant region of space is attracting whole galaxies towards it. Known as “The Great Attractor”, it must be monumental in size to generate such a gravitational pull; in fact, many physicists argue that it is physically impossible for such a massive object to exist at all.
Humans can live unprotected in space for about 30 seconds if they don’t hold their breath.
Cockroaches grown in space became quicker and stronger than their terrestrial counterparts.
