10 Facts About Outer Space

Here are 10 astronomical facts about space you probably didn’t know. Or maybe you did. I had nothing better to do today.

You see that little white marshmallow in the sky? Yes, the moon. Well the “moon” is drifting away from Earth at a rate of 3.8 cm per year. Isn’t that just dandy? I propose we all sing Baby Come Back to convince the moon to not drift away from us.

Since the white marshmallow is moving away from us, the Earth is slowing down. Every 100 years, Earth’s rotation will be 2 milliseconds slower. This means that 100 years from now, the day will be 2 milliseconds longer. Think of all the extra activities we will be able to do!

Twwoo…


Space is completely silent. Like the g in lasagna. Since there is no atmosphere in space, space will always be silent.

You are probably wondering how can astronauts communicate? Through radio waves. Contrary to popular belief, these aren’t radios that are out there waving to the astronauts. Those are just light waves. Light does not need any air to travel.

Now that I think about it. Is this why people always tell me to sing in outer space? So no one can hear me…

I know there is supposed to be an h in three, but the black holes ate it. There are currently 14 known black holes. However, there are way more black holes than 14. There are just so many in our universe that it is impossible to count them all. Good news is that these known black holes aren’t close enough to us to pose any threat. Closest one to us is 8,000 light years away.

Stellar black holes are formed when the center of star collapses. When this occurs, it creates a supernova. A supernova is an exploding star that blasts part of the star into space (NASA).

Black holes can only absorb things that cross their horizon. You can’t see a black hole because they absorb light. It’s also possible for them to collide and merge.

Foouurr…

It is a myth that the big dipper is a constellation. It is actually an asterism. Looks like someone dipped their hands on the wrong site.

The big dipper is a really small part of the Ursa Major constellation.

Fiivvvee…


Astronauts can’t burp in outer space. So much for burping the ABCs.

Siixx…


Any free moving liquid will form a sphere. This is primarily due to the increased surface tension and low gravity.

Seevvenn…


Why was six afraid of seven? Because the Apollo astronauts’ footprints will likely stay on the moon for at least 100 million years!

Since there is no wind or water to erode or wash away any markings on the moon, any markings (footprints, roverprints, etc) will stay nicely preserved for a while.

We should have outlined a picture of a cat on the moon just to confuse the aliens.

The sun is so big that it accounts for roughly 98% of our entire solar system. It is so big that 1.3 million Earths could fit inside of it.

Every second, the sun fuses approximately 600 million tons of hydrogen and helium molecules resulting in 4 million tons of matter to energy conversion as a byproduct.

Niinnee…


In outer space, two flat surfaces of a similar metal will stick together permanently if they touch. Also known as cold welding. Gives me the shivers at night.

You become taller in space. So if you ever wanted to be 6 feet tall, there is your chance. However, you only grow about 5 cm in space.

Hop you guys enjoyed these fun facts. I know I enjoyed writing them. Leave a comment below if you would like to share more.
