Space is full of wonder, beauty, and mystery. Space is so vast and mysterious that scientists are still discovering new things about it on a daily basis.
Whether you are an astronomy enthusiast or just a curious person, there are 5 space facts that will amaze you below.
Space is Totally Silent
Did you ever scream in your dream and nobody could hear you? That’s what it’s like in space.
There’s no air in space, so sound cannot travel. In contrast to Earth, where sound travels on air, space is a vacuum. Therefore, even if a rocket blows up in space, no sound will be heard.
Astronauts communicate with one another through radios, not voices.
A Day on Venus is Longer Than Its Year
This one is quite unusual!
Venus rotates around once in approximately 243 Earth days (1 day on Venus). However, it takes only 225 Earth days to orbit the Sun (1 year on Venus).
That means one day on Venus is longer than a full year on Venus!
One Million Earths Can Fit Inside the Sun
The Sun is gigantic. You might think Earth is large, but next to the Sun, it’s small. Actually, there are approximately 1 million Earths that would fit inside the Sun. The Sun contains 99.8% of the mass in our whole solar system. That is why it is so gravitationally powerful and holds all of the planets in orbit. The following video is about space:Space Isn't That Far Away
We tend to think of space as really, really far away. But actually, space starts just 100 kilometers (62 miles) above the surface of the Earth.
That’s known as the Kármán line, and that’s where the atmosphere leaves off and space takes over.
If you could drive vertically, you’d be in space in an hour or so!
Neutron Stars Are Super Heavy
Neutron stars are the remains of dead stars. Despite being tiny (only 20 km across), they are super heavy. One teaspoon of material from a neutron star would weigh about 6 billion tons on Earth! That’s more than all the cars on Earth put together. Imagine holding that in your hand!Final Thoughts
Space is full of incredible things we are still learning about. From empty quietness to stars weighing billions of tons, the universe has plenty of surprises in store. These five facts are only the tip of the iceberg.
