10 Interesting Space Facts That’ll Blow Your Mind!

The outer space is truly amazing.

Why? Because with new space discoveries happening weekly and just by the sheer vastness of it, with much more than trillions of objects in the billions of galaxies of the universe is almost incomprehensible to the human brain.

Do you think space is completely empty? I thought it was empty too.

But, its basically a solid vacuum containing a low density of particles, mostly a plasma of Hydrogen or helium as well as electromagnetic radiation, neutrinos, and most importantly dust. To put things into perspective, it’s like dropping a tennis ball(all the particles) on the vast ocean (vacuum), the ocean is comparatively way too small though.



1. 99.86% of our solar system is taken up by the Sun’s mass!

The sun is made of three-quarters hydrogen and helium for most of its remaining mass, the Sun accounts for 99.86% of the mass in our solar system with a mass of around 330,000 times that of Earth.

2. There’s WATER in Space!

Who would have thought water exists in space? It does but in vapor form. Astronomers have found a massive water vapor cloud which holds 140 trillion times the mass of water in the Earth’s oceans somewhere around 10 billion light years away – making it the largest discovery of water ever found.

3. Space is completely Silent!

Pin drop silence! We have all heard this phrase from our teachers :p. Well, space is completely silent because of the absence of an atmosphere which means that sound has no medium or way to travel to be heard. Astronauts use radios to stay in communication while in space, since radio waves can still be sent and received.

4. Space is considered to be of Infinite size!

We were talking about dropping pins right? If you eject a pin into open space, it will keep move forward in that direction forever. The problem is we don’t have enough resources to follow it.

Due to this unimaginable size it is impossible to accurately predict just how many stars exist in space. Right now, scientists and astronomers use the number of stars only within our galaxy that is The Milky Way, to estimate. That number is between 200-400 billion stars and there are estimated to be billions of galaxies so the stars in space really are completely uncountable.

5. Halley’s Comet won’t orbit past earth again until 2061!

Discovered in 1705 by Edmond Halley, the famous comet was last seen in 1986. It is a “periodic” comet and returns to Earth’s vicinity about every 75 years, making it possible for a human to see it twice in his or her lifetime. He basically examined reports of a comet approaching Earth in 1531, 1607 and 1682. He concluded that these three comets were actually the same comet returning over and over again, and predicted the comet would come again in 1758.

6. A full NASA Space Suit cost 12 million$!

A fully equipped spacesuit is really a one-person spacecraft made up of 14 layers of material designed to protect astronauts in space. 70% of the cost is for the backpack and control module. It can handle insane temperatures ranging from -250 to 250 degrees on earth. No difference exists in a male’s or female’s suit, though the female astronaut usually requires a smaller size.

7. The highest mountain discovered is the Olympus Mons, which is located on Mars!

Olympus Mons is a volcano on Mars that may still be active, according to scientists.

Its peak is 16 miles (25.75 km) high and Mt Everest being 5.5 miles (8.85 km), making it nearly 3 times higher than Mount Everest.

And not only is it tall, but it’s also 374,015 ft² (114,000 m²) wide – that’s an area the size of Arizona!

8. One day on Venus is longer than one year on Earth!

Venus is unusual because it spins the opposite direction of Earth and has a slow axis of rotation. It takes about 243 Earth days to spin around just once. Because it’s so close to the sun, a year goes by fast. It takes 225 Earth days for Venus to go all the way around the sun. That means that a day on Venus is a little longer than a year on Venus.

Just like Mercury, Venus doesn’t have any moons.

9. Venus is the hottest planet in the solar system!

Yup, it’s not mercury, even though it is closest to the sun. Since Mercury has no atmosphere to regulate temperature it has a very large temperature fluctuation. Any heat that Mercury receives from the sun is quickly lost back into space.

Venus has an average surface temperature of around 450° C. Venus is very close to the actual size of the earth and viewing it has been difficult due to a very thick atmosphere of carbon dioxide. This thick atmosphere makes the surface of Venus hotter because the heat doesn’t escape back into space. Venus has what is called a runaway greenhouse effect.

10. Cold welding occurs if two pieces of the same material collide!

When two pieces of the same material collide they merge together to form a bigger sized uni piece. It happens because the atoms of two pieces of metal have no way of knowing they are separate and combine together just like magnets attract. This doesn’t happen on Earth because of the air and water found between the pieces.

 

These were my top picks from tons of space facts which I did not know of. Outer Space is truly fascinating and mysterious!

“There were only the great diamonds and sapphires and emerald mists and velvet inks of space, with God’s voice mingling among the crystal fires.”
