Just 22 incredibly interesting facts about space


The largest star known to man is 1700 times larger than the sun!


If you put a file Finger over a star in the skyYou block photons that traveled to Earth unobstructed millions of years ago It finally enters your eye.

Photons are a basic unit of light. It is made in the midst of a star and will travel millions of years before reaching Earth. When you block a star in the sky with your finger, you are really blocking photons that are a million years old from entering your retina.


Do you know where Coldest place In the known universe? what about The Most exciting? Well, they are both here on Earth!

Well, they are they were. The coldest temperature ever recorded in the universe was created here in a laboratory on Earth (-273 degrees Celsius, or absolute zero), and the Large Hadron Collider also managed to create the highest temperature ever recorded since the universe began its Big Bang (5.5 degrees Celsius). Trillion degrees kelvin).


And in about 4.5 billion years, it was The Milky Way is expected to collide Andromeda galaxy, our closest galaxy, to form a giant elliptical galaxy.

And our great red neighbor, Jupiter is twice its size Like all other planets in our solar system combined!

Only one part of the planet’s surface – a 150-year-old giant storm called the “Great Red Spot” – is itself twice the size of the Earth!


There is a planet in our galaxy where daytime temperatures can reach over 1000 ° C and possibly It rains molten glass horizontally About 4,500 miles per hour!

The planet, known as HD 189733b, was observed with NASA’s Hubble Space Telescope and is cobalt blue.


Scientists believe they have found The parallel universe in a vacuum It is 1 billion light-years across.

It is a somewhat controversial hypothesis, but the void – which is void of every substance – may be evidence of a multiverse. Discovered in 2007, it is 40 times larger than the largest previously recorded void.


So we know that light takes a long time to travel through space, right? Well, there really is Some parts of the universe we cannot see Because the light from there has not yet reached us.

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


Soon though, though James Webb Space Telescope It will allow us to explore galaxies that formed in the early universe, and watch stars as they form planetary systems.

Did you know that there is an estimate 500,000 pieces of space debris Floating above the ground and moving at speeds of up to 17,500 mph?

Space debris is basically anything we’ve carelessly left to float in space – bits of rockets, dead satellites, and whatever you have.

It’s mostly the largest satellites that have survived the fiery reentry, and truth be told, they often land in the ocean (LAV) or some remote area. There is an entire team of researchers dedicated to tracking space debris and monitoring the risk of colliding with Earth – as far as we know, no one has died from hitting a little old satellite!


But here’s the thing, there is such Phenomenon such as the Kessler EffectOne devastating event in low Earth orbit could cause all satellites to shatter into smaller and smaller pieces until the planet is surrounded by a massive cloud of shrapnel.

This would make having to leave Earth almost impossible.


over there A rogue supermassive black hole Speeding through space at about five million miles per hour.

Usually, every galaxy contains a black hole, but this galaxy has been ejected from its galaxy, 3C 186. This may be the result of the collision of two galaxies, which may have united black holes. Astronomers predict that within 20 million years, it will emerge from its galaxy and roam the universe forever.

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

Venus today is a living hell. It has a stifling atmosphere of carbon dioxide and almost no water vapor; Temperatures there reach 462 degrees Celsius! But climate modeling suggests that ancient Venus may have had oceans and a dry land pattern just like ours. Various factors – including the water-to-Earth ratio, and the idea that clouds likely shielded Venus from strong sunlight – suggest that the planet may have been habitable someday.

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

These rogue planets do not orbit a star, and so it’s very difficult for us to glimpse them – we actually don’t know if there is any close to them at all. However, statistically, it is not close enough to be a concern and we are really a very small target given the size of the solar system.

According to Neil deGrasse Tyson, the Dark Matter is the oldest unresolved mystery in modern astrophysics. In fact, it might not be is being Thing! Basically, the amount of gravity in the universe is not exactly equal to the amount of observed mass – planets, stars, galaxies, comets, black holes and dark clouds. So scientists suggest that there is a great deal of unobserved or “dark” mass in the universe, which is the source of all that gravity.

This idea is based on prof A complex theory known as vacuum decay – basically a self-destruct button for the universe! It’s just speculation at this point, but it’s about whether the universe is in a right or wrong void – true void is stable, but false void isn’t. If the random quantum oscillation allowed the false vacuum to release its potential energy, it would create a bubble of true vacuum that would expand at the speed of light and delete everything it touches. The destruction would be immediate and depending on where it happened in the universe, we might never see it coming. Remember, this is just a theory!


Finally, this is not a fact in and of itself, but have you ever thought about the possibility that we actually sent a message to an alien race in the distant past and it’s still making its way to them?

Space is huge, we’ve proven it now, and there’s every chance that we actually sent a message into space thousands of years ago and forgot about it (think how societies have changed over time). We may still be waiting for this message to arrive, or wait for a response back. In this sense, we will constantly introduce ourselves over and over again to anyone else who might be …
