These space facts fromAsk Redditare out of this world.
1.You could survive 90 seconds unprotected in space.

But a chimpanzee can last up to 3 minutes.
2.Neutron stars are so dense that a teaspoon of material from one would weigh around 10 million tons.
3.Most of the visible stars in the night sky are binary stars, two stars orbiting each other.
4.Neptune was discovered using math.
5.After traveling since 1977, Voyager 1 has now reached about 20 Light-HOURS distance from the Sun.
Vast does not begin to describe the Universe.
6.There are two confirmed oceans in the solar system.
One on Earth, and one on Saturns moon Titan.
The biggest difference is Titan is about -180 C. The ocean is liquid methane.
It even has waves that get as high as (wait for it) a couple of centimeters!
7.Jupiter has over 70 moons (and well on the way to 80 as of today!)
Whatever the direction of the other planets is when they are rotating, Venus rotates the exact opposite way.
10.Being able to see a total solar eclipse is a sheer coincidence of timing.
This wont happen for 600 million years though, so dont panic.
12.Even though there is no air, space stinks.
13.Objects in orbit are not in zero gravity, but in a controlled freefall.
16.If the sun dies, itll take 8 minutes for us to realize.
17.The age of the universe is not a single number.
18.Saturns tiny moon Enceladus has volcanoes that spew ice particles at speeds faster than the escape velocity.
The particles leave Enceladus atmosphere and get pulled into Saturns ring system forming the E ring!
19.You could fit all the planets in the solar system in the space between Earth and the Moon.
22.There are clouds of alcohol floating in space.
24.So far, only 3 people have actually diedinspace.
But from our perspective, black holes are some of the oldest, and longest-living objects in the universe.
So from the perspective of the singularity, it exists at only one, infinitely small amount of time.
With this in mind, a black hole would not be an object, it would be an event.
26.There is verifiable evidence that at least three astronauts survived the initial explosion of the Challenger in 1986.
27.About 6.63 quadrillion Earths can fit in the largest (discovered) star.
28.Theres an anomaly called the Bootes Void.
Its kind of scary, in an existential way.
29.The universe is still in its very infancy.
Blue Dwarfs: Red dwarfs that have started spending the last of its hydrogen.
The first of this kind of star is not expected to exist until a trillion years in the future.
But, when a white dwarf star cools down, it starts the process of becoming a black dwarf.
This process can theoretically take as little as a quadrillion years, or as much as 37 quadrillion years.
The enormity of the universe is mind-boggling.
