If you are looking for some weird astronomical facts about space that will blow your mind, you have come to the right place!
Approximately, there are 300 billion stars in our universe. Don’t you think this is interesting? Andromeda, our closest galaxy neighbor, has trillion suns. Ultimately, each universe is filled with countless planets, comets, and asteroids. There are 8.8 billion habitable Earth-sized planets in our galaxy alone.
The universe is a wonderful prominent place!
Therefore, it is almost impossible to compile a list of astronomical facts, since we have also discovered some of the cosmic mysteries. However, here are 15 amazing facts about the place.
1. The Sun is the most massive object in the solar system
The Sun is responsible for 99% of the mass of our solar system. Our star is so dense that it comprises 99% of the mass of our entire solar system. It is the same with all planets dominating gravity.
Technically, our Sun is a “G-type main-sequence star,” meaning it mixes 600 million tonnes of hydrogen with helium every second. This translates into 4 million tonnes of matter to energy.
2. If two pieces of the same metal touched the space, they would be trapped together
On Earth, if you touch two pieces of the same metal together, you can disassemble them, but in space, this is not so. Earth contains oxygen in the atmosphere, creating a thin, oxidized metal layer, which acts as a barrier between the two metals. There is no atmospheric oxygen in space, and as a result, there is no barrier, so the two metals form a bond and become one.
3. The Pistol Star is about 10 million times the Sun’s brightness.
The Pistol Star is one of the largest stars in the universe, about 25,000 light-years from Earth in the direction of Sagittarius. The Pistol Star has a mass of 100-150 times greater than the Sun and is 10 million times brighter, which makes it one of the brightest stars. It may be visible to the naked eye as a fourth magnitude star, but is completely hidden from view due to interstellar dust.
4. There are more stars in the galaxy than grains of sand on Earth
The size of the universe is mind-boggling and difficult to understand. Astronomer Carl Sagan is known for having more stars in the universe than sand grains on the world’s deserts and beaches, but this is difficult to prove.
5. No one in the space could hear anything
You can see it in Star Wars, but the place is completely silent. Sound waves can only travel through a medium. No sound waves travel through the void of space.
Radio waves can travel in space, so if you’re ever in space, get into the radio, and we’ll listen to you.
6. There is a huge body of water that flows into space
It is almost odd when the water is almost incomprehensible, and the outer space is generally considered a desolate and dry place. Water is found around the huge black hole involved in the process of absorbing the material, sprinkling a lot of energy, which is called a quasar. Water produces energy waves that bind hydrogen and oxygen atoms.
7. All-stars, galaxies, and planets make up only 4% of the universe
Although we know a good amount about the space, it really is a penny at sea. Of all the detectable stars, galaxies, planets, and other objects, only 4% are visible. While the remaining 96% are not seen, discovered, or understood by astronomers.
8. The footprints left on the moon are not visible due to the wind
There is no wind in space? But wait a minute! If the wind doesn’t blow them, why the flag? Well, it really isn’t. You will see an astral telescopic horizontal rod trying to remove the astronauts from the top of the flag.
9. Pluto is smaller than America
If we walk around the equator of Pluto, it will be the same distance from London to Denver. The distance is nearly 56 miles. Pluto is even smaller than the moon of the Earth. This dwarf planet Pluto takes around 248 Earth years to go around the Sun.
10. There are more volcanoes on Earth than any other planet in our solar system
There are over 1,600 major volcanoes on the surface of Venus, including Mount Mons, a 5 mile or 8 km high volcano. It comprises 90% of the basalt surface and 65% of the planet’s volcanic lava plains, indicating that the volcano played an essential role in shaping its surface.
11. Any fluid that moves freely in space becomes a sphere
Whether water sits in a pond or a glass of water, Earth’s gravity pulls the liquid down into the shape of the container. The reason for this is the so-called surface tension, which is an imbalance of attractive intermolecular forces. It also occurs in the lower orbit.
12. Outer Space is 62 miles away
Although the spacecraft has no official physical boundaries, the Carman Line is 62 miles above sea level, which is traditionally used for space contracts or space records.
13. Our solar system takes about 230 million years to orbit the Milky Way
Everyone knows that it takes 24 hours for the Earth to rotate around its axis, and 365 days for the Sun to orbit, but we don’t hear much about the galactic year. This is because our solar system is estimated to take 225 to 250 million years to orbit in the middle of the Milky Way.
14. The universe will probably explode at some point
One theory known as the “Big Rip” theory is that in the next few billion years, “dark energy” could become powerful that it would break everything in the universe into nuclear and subatomic particles and eventually collapse into space.
15. You can get electricity from outer space
If you are stuck in space with a rod, Tesla assumes that the difference in temperature between space and Earth creates a motor that can drive the motor. While driving the motor may be a problem, it is certainly possible.
