22 incredibly interesting facts about space

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.

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).

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!

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

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.

The universe is so huge that the light from these galaxies that formed during the Big Bang still hasn’t reached us!

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 reentry were the larger satellites. To be honest, they usually landed in the ocean (er) 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!

This will make it almost impossible to leave the earth.

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 cause the two black holes to merge. 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 After billions of years, Voyager 1 may still be moving in space at the same time.

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 once.

This is called “cold welding”, and this happens because two separate atoms don’t know that they belong to different pieces of metal, 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 don’t actually 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 Deglas 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 create a real vacuum bubble that 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!

Space is huge, we have now determined this, and it is very likely that we have sent a message to space thousands of years ago, but have forgotten 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 be returned to us. In this sense, we will only continue to introduce ourselves over and over to other people who might be there…
