Just 22 incredibly interesting facts about space


The largest known star is 1,700 times larger than the Sun!

If you keep it Finger on a star in the sky, You are resisting photons from which you have traveled to the unused world for millions of years Finally enters your eyes.

Photons are an elementary unit of light. These are formed at the center of a star and will travel millions of years before they reach Earth. When you touch a star in the sky with your finger, you are really blocking millions of years old photons from entering your retina.

Do you know where? The coldest place What is there in the known universe? How? The hottest? Okay, they’re right here in the world!

Well, they are Was. The coldest record temperature in the universe was created here in a lab on Earth (-273 degrees Celsius or absolute zero) and the Large Hadron Collider has been able to create the highest record temperature since the universe began with the Big Bang (5.5) trillion degrees Celsius.

And about 4.5 billion years, The Milky Way is expected to collide Andromeda galaxy form our nearest galactic neighbor to form a large elliptical galaxy

And our big ol ‘red neighbor, Jupiter, twice as big All the other planets in our solar system!

Just one section of the planet’s surface – a huge, 150-year-old storm known as the “Great Red Spot” – is twice the size of Earth!

7.

There is a planet in our galaxy where daytime temperatures can reach over a thousand degrees Celsius, and this is probably It is raining molten glass in the sky About 4,500 miles per hour!

The planet, known as HD 189733B, was observed using NASA’s Hubble Space Telescope and is a cobalt blue color.

Scientists think they are a Parallel universe into a void Measure one billion light years.

This is a fairly controversial hypothesis, but invalid – which is zero in all respects – it could be evidence of a multiverse. Discovered in 2007, it is 40 times larger than the previously recorded zero.

So we know that light takes a long time to travel through space, doesn’t it? Okay, there actually is Some parts of the universe we do not see Because the light from there has not yet reached us.

The universe is so wonderful that the light from these galaxies, which formed during the Big Bang, has not yet reached us!

10.

Although, soon James Webb Space Telescope This will allow us to explore the galaxies that formed at the very beginning of the universe and to observe the stars that make up the planetary system.

Did you know that there is a guess 500,000 pieces of space debris Floating above the earth and traveling at a speed of 17,500 miles per hour?

Space debris is basically something that we carelessly left floating in space – rocket bits, dead satellites, what do you have.

These are mostly larger satellites that have survived the process of redesigning the fire, and it is true that they do not often land at sea or in remote areas. There is a team of researchers dedicated to monitoring the wreckage of space and the risk of it colliding with Earth – as far as we know, no one has been hit by an old satellite and no one has died!

But here’s the thing Events as the effect of Kessler, As a result of a destructive event in the Earth’s lower orbit, the planet can be shattered into smaller and smaller pieces until it is surrounded by larger clouds.

This makes it almost impossible to leave the earth.

There is one Rogue supermassive black hole Speed ​​through space with five million miles per hour.

Normally, each galaxy has a black hole, but this is one of the galaxies in its orbit, 3C186. This is probably the result of two galaxy collisions, which could unite the two black holes. Astronomers predict that in 20 million years, it will split its galaxy and orbit the universe forever.

The investigation began back in 1977 to study Jupiter and Saturn and is now on a second mission outside the solar system. It will now flow forever through inland space. The earth will Probably steam by the sun In a few billion years, already Voyager 1 will probably still run through space.

Venus is living hell today. It has a suffocating carbon dioxide atmosphere and almost no water vapor; The temperature there reached 462 degrees Celsius! Climate modeling, however, suggests that ancient Venus may have a sea and arid land pattern like ours. Various factors, including the ground ratio of water and clouds, give the idea that Venus protects Venus from strong sunlight – the planet was once habitable.

This is known as “cold welding”, and it happens because the atoms of both individual bits do not know that they belong to different pieces of metal, so they join together. This does not happen on earth because air or water always separates the pieces.

These rogue planets do not orbit any stars and so it is very difficult to get a glimpse of them – in fact we do not know if there is any place nearby. Statistically speaking, these are not enough to worry about and in fact we are a very small target in terms of the size of the solar system.

According to Neil Degrass Tyson, dark matter is a long-standing unsolved mystery in modern astronomy. In fact, it may not even be Stay Matter! Basically, the amount of gravity in the universe is not equal to the amount of observable mass – planets, stars, galaxies, comets, black holes and dark clouds. So scientists have suggested that there is a huge measure of unforgettable or “dark” mass in the universe, which is the source of all this gravity.

This idea is based on a The complex theory is known as vacuum decay – Basically a self-destructing button for the universe! This is only speculative at the moment, but it comes down to whether the universe is in true or false emptiness – true emptiness is stable, but false vacuum is not. If a random quantum fluctuation allows a false vacuum to reveal its potential energy, it will create a bubble of true emptiness that will expand at the speed of light and erase everything it touches. The destruction will be instantaneous and we will never see it come, depending on where it happened in the universe. Remember, this is just a theory!

And lastly, it’s not as true as every goal, but have you considered the possibility that we’ve already sent a message to an alien in the distant past and it’s still reaching them?

The space is huge, we have just established it and thousands of years ago we already sent a message into space and forgot about it (think about how societies change over time). We can either wait for that message to arrive, or wait for the answer to return to us. In that sense, we’re just constantly introducing ourselves to someone else who might be out there …
