Barnorama All Fun In The Barn
Space is full of surprises, and these 15 weird facts are proof that the universe is even stranger than we can imagine.
The universe is vast, and much stranger than you know.
We’ve barely scratched the surface of researching outer space, but what we’ve learned so far is literally otherworldly. On Mars, there’s a 13-mile-high volcano. The atmosphere of space warps and deforms the bodies of astronauts permanently. The moon quakes more than California, and there are even gargantuan space clouds full of alcohol light-years away.
Set out into the unknown and come back with weird knowledge that can only be obtained off-planet.
Earth has more trees than the Milky Way has stars
There are about 3 trillion trees on Earth and about 350 billion stars in the Milky Way.
