Earth may have actually had two moons at one point.
And no, we’re not talking about 3753 Cruithne and Asteroid 2002 AA29. According to Space.com, it’s possible (but not proven) that Earth might have had another moon—one about 750 miles wide. Scientists that buy into this theory hypothesize that this tiny moon may have crashed into the other one.
The largest living thing in the world is a fungus.
A massive fungus, at that! Known as the honey mushroom (or Armillaria), this fungus spans 2,200 acres across Oregon.
The oldest shark in the world is a Greenland Shark.
In fact, according to Live Science, Greenlands are so old they don’t even have backbones. These sea creatures grow to be as mature as 392 years old.
Greenland has the lowest population of any country on Earth.
A 2016 census found that 55,847 people lived in 836,330 square miles in Greenland with most communities sitting on the coastline.
Earth used to be purple… apparently.
Some experts—like Shil DasSarma—believe that Earth may have been purple at one point in time. Fueling that fire is the fact that ancient microbes may have relied on a different molecule other than the green chlorophyll to grab the sun’s rays. Instead, that molecule—retinal—could have made things we know as green today look more purple.
The moon may have been formed as the result of a collision.
Not a ton of information is known about how the moon was created, but one hypothesis claims that a planet, asteroid, or perhaps a comet—called Theia—collided into Earth, resulting in debris flying into space. That debris may have formed the moon as we know it today.
One of Earth’s coolest phenomenons is the Auroras.
Known colloquially as the Southern Lights or Aurora Australias, Aurora Borealis, or Nothern Lights, Auroras happen when particles from the sun collide with the upper atmosphere of Earth near the poles. According to Space.com, this results in a sort of rainbow of lights twinkling in the sky, like a crystal in the sun.
Earth’s magnetic north pole is moving northward.
NASA has said that Earth’s magnetic north pole has slowly moved northward by more than 600 miles since the early 19th century. As of right now, the pole is moving at about 40 miles per year.
