Random Creepy Facts About Outer Space You Can't Unlearn (25 items)

(#12) A Majority Of 'Earth 2' Is Uninhabitable

Gliese 581g, an exoplanet 20 light-years from Earth, is considered the prime candidate for human re-colonization should Earth's resources be expended. Locked in orbit around a red dwarf star known as Gliese, one side of the planet reaches temperatures as cold as the North Pole while the other is plagued by excessive heat.
While one strip of the planet suggests the possibility of future habitation, the sky would glow a perpetual red and any plants would grow in an unappetizing black due to the weakness of the red dwarf in comparison to our own sun.
(#13) There Are Sounds In Space

Though popular thought contends that outer space is a vacuum, in actuality -- interstellar dust is so dense in some areas that it can carry sound waves. Though these waves would be imperceptive to humans.

Some sounds in space may include the humming of a massive black hole, the groans of Earth as its crust shifts, and the residual sound of the universe expanding.
(#17) Free-Floating Planets May Outnumber The Stars

In 2011, astronomers discovered numerous Jupiter-sized planets free-floating apart from any star. The team hypothesized that the rogue planets were ejected from distant developing planetary systems, and estimated that there may be twice as many of these free-floating worlds as there are stars.

Potentially even more numerous are free-floating planets smaller than Jupiter and Saturn, as their reduced mass allows them to be more easily ejected from their systems.
(#15) Feces Float

The crew members of Apollo 10 discovered that the makeup of feces combined with the diet of astronauts rendered it bouncy and pong-like. At one point during the mission, feces was loosed from its container due to its sponginess, causing a stir among the astronauts.
(#4) Astronauts Must Drink 730 Liters Of Recycled Sweat And Urine To Live In Space For A Year

Water is a limited resource in space - because of this, astronauts must resort to recycling their own waste. NASA astronaut Scott Kelly consumed approximately 730 liters of recycled urine and sweat during his yearlong mission.
(#6) Solar Superstorms Could Cause Blackouts Worldwide

In July of 2012, a coronal mass ejection (CME), referred to as a solar superstorm by the media, tore through Earth's orbit and collided with the STEREO-A spacecraft. According to Daniel Baker of the University of Colorado, had the superstorm occurred one week earlier, Earth would have received the impact and devastating after-effects.
