22 amazing facts about space

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


If you place yours finger on a star in the skyYou are preventing the photons that have traveled to Earth without being disturbed millions of years since finally caught your eye.

Photons are a basic unit of light. They are created at the center of a star and will travel for millions of years before reaching Earth. When you block a star in the sky with your finger, you are actually blocking millions of years old photons from entering your retina.


Do you know where coldest place in the known universe? How about hottest? Well, both are right here on Earth!

Well, they was. The coldest recorded temperature in the universe was created here in a laboratory on Earth (-273 degrees C, or absolute zero) and the Large Hadron Collider also produced the hottest temperature yet. recorded since the universe began with the Big Bang (5.5 trillion kelvin degrees).


And for about 4.5 billion years, The Milky Way is expected to collide with Andromeda, our closest neighbor, to form a giant elliptical galaxy.

And our great red neighbor, Jupiter, twice as big like all the other planets in our solar system combined!

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


There is a planet in our galaxy where the temperature during the day could reach more than 1,000 degrees Celsius and possibly horizontally melted glass rain at about 4,500 miles / hour!

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


Scientists think they have found one parallel universe in space across a billion light-years.

It’s a controversial theory, but the void – the emptiness of all matter – could be proof of the 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 are some parts of the universe we cannot see because the light from there has yet to reach us.

The universe is so vast that the light from these galaxies, formed during THE BIG BANG period, has yet to reach us!


Soon though James Webb Space Telescope will allow us to explore galaxies formed from the very beginning of the universe, and observe the stars forming planetary systems.

Did you know that there is an estimate 500,000 space debris hovering over the Earth and moving around at speeds of up to 17,500 miles an hour?

Space debris is basically anything we’ve been careless about to hover in space – rocket debris, dead satellites, and you.

That is most of the larger satellites that have survived the fiery test and, truthfully, they more often than not land in the ocean (ugh) or in some remote area. There’s a whole team of researchers dedicated to tracking space debris and tracking its risk of colliding with the Earth – as far as we know, no one has died from being hit by an old satellite!


But here’s the thing, there’s one a phenomenon like the Kessler Effectwhere a single destructive event in low Earth orbit could cause all satellites to break into smaller and smaller pieces until the planet is surrounded by a large cloud of bomb debris. .

This will make it almost impossible to leave Earth.


Only one scam super big black hole Accelerate progress in space with about five million miles per hour.

Normally, every galaxy contains a black hole, but this galaxy has been ejected from its home galaxy, 3C 186. This may be the result of two galaxies colliding, which may have been combined. both black holes. Astronomers predict that in 20 million years, it will break out of its galaxy and wander through space forever.

The probe was launched in 1977 to study Jupiter and Saturn and is currently on a second mission beyond the solar system. It will now pass through interstellar space forever. Earth will can be evaporated by the sun In the next few billion years, meanwhile, the Voyager 1 could still be traveling through space.

Venus today is a living hell. It has a stuffy carbon dioxide atmosphere and almost no water vapor; the temperature there reached 462 degrees Celsius. But climate models have suggested that ancient Venus might have oceans and dry land models like ours. The various factors – including the ratio of water to earth and the idea that the clouds were capable of shielding Venus from strong sunlight – suggest that the planet may once have been inhabited.

This is called “cold soldering”, and it happens because the atoms of both individual bits do not know that they belong to different metal fragments, so they are bound together. This doesn’t happen on Earth because there’s always air or water separating the debris.

These spoof planets don’t orbit a star, and so it’s difficult to see them – in fact, we really don’t know if there are any nearby planets. Statistically, though, they’re not close enough to cause concern, and we’re actually a pretty small target given the size of the solar system.

Dark matter is the longest-standing mystery in modern astrophysics, according to Neil deGrasse Tyson. Indeed, it might not even be was problem! Essentially, the gravitational force in the universe is not quite as much as the observable mass – planets, stars, galaxies, comets, black holes and dark clouds. So scientists propose to have a large measure of the unobservable or “dark” mass in the universe, which is the source of all that gravity.

This idea is based on one Complex theory is called vacuum decay – is basically a self-destruct button for the universe! It is only speculation at this point, but it depends on whether the universe is in a real vacuum or a false vacuum – the real vacuum is stable, but the false vacuum is not. If a random quantum oscillation allows a pseudo-vacuum to release its potential energy, it creates a true vacuum bubble that will expand at the speed of light and erase everything it touches. . The destruction will be instantaneous and depending on where it happens in the universe, we may never see it coming. Remember, this is just a theory!


And in the end, this is not the case, but did you consider the possibility that we sent a message to an alien race in the distant past and it still finds its way to them?

The space is huge, we have set that up until now, and it’s likely we sent a message into space thousands of years ago and forgot about it (think about how society changed by time). We may still be waiting for the message to arrive, OR waiting for the reply to be sent back to us. In that sense, we’ll be constantly introducing ourselves over and over with anyone else who might be out there …
