22 incredibly interesting facts about space

The largest star known to mankind is 1,700 times larger than the sun!

1.

If you take your Finger stroke a star in the sky, You are stopping photons that have reached the earth undisturbed for millions of years Finally came into your sight.

Photon is the basic unit of light. They are made in the center of a star and will travel millions of years before reaching the earth. When you block a star in the sky with your finger, you are actually preventing photons from millions of years ago from entering your retina.

Do you know where The coldest place What is in the known universe?How hottest? Well, they are all on earth!

Well they YesThe coldest temperature recorded in the universe was created in a laboratory on Earth (-273 degrees Celsius, or absolute zero), and the Large Hadron Collider also managed to create the hottest temperature recorded since the beginning of the Big Bang (5.5 trillion degrees Kelvin).

4.

After about 4.5 billion years, The Milky Way is expected to be The Andromeda Galaxy, our nearest galaxy neighbor, forms a huge elliptical galaxy.

6.

And our big red neighbor, Jupiter is twice as big As the sum of all the other planets in our solar system!

Only part of the earth’s surface-a huge, 150-year-old storm called the “Great Red Spot”-is itself twice the size of the earth!

7.

There is a planet in our Milky Way. The temperature during the day can reach 1000 degrees Celsius. It may Horizontal raining molten glass It’s about 4,500 miles per hour!

This planet is called HD 189733b and it was discovered using NASA’s Hubble Space Telescope. It has a cobalt blue color.

8.

Scientists think they have found Parallel universe in the void A billion light-years in diameter.

This is a controversial hypothesis, but the void—without any matter—may be evidence of the multiverse. It was discovered in 2007 and is 40 times larger than the largest hole previously recorded.

9.

So we know that it takes a long time for light to travel in space, right?Well, actually there is We can’t see some parts of the universe Because the light there hasn’t reached us yet.

The universe is so huge that the light from these galaxies that formed during the Big Bang has yet to reach us!

10.

Although, soon James Webb Space Telescope It will allow us to explore the galaxies that formed at the beginning of the universe and observe the stars that formed planetary systems.

do you know? 500,000 pieces of space debris Floating above the earth and moving at speeds of up to 17,500 mph?

Space debris is basically anything we accidentally left floating in space-rocket debris, dead satellites, what do you have.

The main ones that survived the fiery re-entry were the larger satellites. To be honest, they usually landed in the ocean (uh) or some remote areas. There is a whole set of researchers dedicated to tracking space debris and monitoring the risk of it colliding with the Earth-as far as we know, no one has died from being hit by a little old satellite!

14.

But the thing is like this, there is such a As a phenomenon of the Kessler effect, Where a single destructive event in low earth orbit may cause all satellites to break down into smaller and smaller fragments until the earth is surrounded by a huge cloud of shrapnel.

This will make it almost impossible to leave the earth.

15.

Have a Rogue supermassive black hole Travel through space at a speed of approximately 5 million miles per hour.

Normally, every galaxy contains a black hole, but this galaxy has been kicked out of its parent galaxy 3C 186. This may be the result of a collision between two galaxies, which may combine two black holes. Astronomers predict that in 20 million years, it will rush out of the Milky Way and roam forever in the universe.

The probe was launched in 1977 to study Jupiter and Saturn, and is now on its second mission to leave the solar system. It will now drift through interstellar space forever.The earth will May be evaporated by the sun In a few billion years, Voyager 1 may still be moving in space.

Venus today is a living hell. It has a suffocating atmosphere of carbon dioxide and almost no water vapor; the temperature there reaches 462 degrees Celsius! But climate models suggest that ancient Venus may have ocean and dry land patterns just like ours. Various factors—including the water-to-land ratio, and the idea that clouds might protect Venus from strong sunlight—suggest that the planet may have been habitable at one time.

This is called “cold welding” because the atoms of two separate positions do not know that they belong to different metal pieces, so they are joined together. This will not happen on earth, because there is always air or water separating the debris.

These rogue planets do not orbit stars, so it is difficult to catch a glimpse of them—in fact, we actually don’t know if there are any planets nearby. However, from the statistical data, they are not enough to attract attention, considering the size of the solar system, we are indeed a small target.

According to Neil deGrasse Tyson, dark matter is the longest unsolved mystery in modern astrophysics.In fact, it may not even Yes thing! Basically, the gravity in the universe is not exactly equal to the observable mass-planets, stars, galaxies, comets, black holes and dark clouds. Therefore, scientists have proposed that there are a large number of unobservable or “dark” masses in the universe, which are the source of all gravity.

The idea is based on A complex theory called vacuum decay -Basically the self-destruct button of the universe! At this point, this is only speculative, but it boils down to whether the universe is in a true vacuum or a false vacuum—a true vacuum is stable, but a false vacuum is not. If random quantum fluctuations allow the false vacuum to release its potential energy, it will produce a real vacuum bubble, which will expand at the speed of light and delete everything it touches. The destruction will be instant, depending on where it occurs in the universe, we may never see it coming. Remember, this is just a theory!

In the end, this is not true in itself, but have you considered the possibility that we have sent a message to an alien race in the distant past and it is still sending messages to them?

Space is huge, we have determined this now, and it is very likely that we have sent a message to space thousands of years ago and forgot about it (think about how society has changed over time). We may still be waiting for the message to arrive, or waiting for a reply to return to us. In this sense, we will only continue to introduce ourselves over and over to other people who might be there…
