Only 22 Incredibly Interesting Facts About Space


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

1.

It puts your own the finger on a star in the sky, prevent photons that have traveled to Earth without being disturbed for millions of years from finally entering your eye.

Photons are a basic unit of light. They are made in the center of a star and travel for millions of years before reaching Earth. When you block a star in the sky with your finger, it actually blocks the photons of millions of years of entry into your retina.

2.

You know where u the coldest place in the known universe is it? what do you think the hottest? Well, they’re both here on Earth!

Well, them they were. The coldest recorded temperature in the universe was created here in an Earth laboratory (-273 degrees Celsius, or absolute zero), and the Large Hadron Collider was also able to create the warmest recorded temperature since that. universe began with the Big Bang (5.5 trillion kelvin).

4.

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

6.

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

A single section of the planet’s surface – a giant 150-year-old storm called the “Great Red Spot” – is itself twice as large as Earth!

7.

There is a planet in our galaxy where the daytime temperature can reach over 1000 degrees Celsius and maybe rain melted glass horizontally at about 4,500 mph!

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

8.

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

It’s a pretty controversial hypothesis, but emptiness – which is emptiness of all matter – can be proof of a multiverse. Discovered in 2007, it is 40 times larger than the largest vacuum recorded before.

9.

So we know that light takes a long time to travel in space, right? Well, there actually are certain parts of the universe we cannot see for the light from there has not yet come.

The universe is so extraordinarily vast that the light from these galaxies, which were formed during the BIG BANG, has not yet reached us!

10.

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

You know there is an estimate 500,000 pieces of space debris floating above the Earth and moving around at speeds of up to 17,500 mph?

Space debris is basically everything left negligently to float in space – pieces of rock, dead satellites, that you have.

These are mostly larger satellites that have survived the burning reentry process and, in truth, are more often landed in the ocean (ugh) or in a remote area. There’s a whole team of researchers dedicated to tracking space debris and tracking its risk of colliding with Earth – as far as we know, no one died from being hit by a little old satellite!

14.

But here’s the thing, there’s such a thing phenomenon such as The Kessler effect, where a single destructive event in Earth’s lower orbit could cause all satellites to split into smaller and smaller fragments until the planet is surrounded by a massive cloud of shrapnel.

This always makes the need to leave the Earth almost impossible.

15.

There is one supermassive rogue black hole accelerating through space to about five million miles per hour.

Usually, each galaxy contains a black hole, but this has been driven out of its home galaxy, 3C 186. This is probably the result of two colliding galaxies, which may have joined the two black holes. Astronomers predict that in 20 million years, it will disembark from its galaxy and roam the universe forever.

The probe was launched in 1977 to study Jupiter and Saturn and is now in its second mission outside the solar system. Now it will drift into interstellar space forever. The Earth will be probably to be vaporized by the sun in a few billion years, meanwhile Voyager 1 will probably still be moving through space.

Venus today is a living hell. It has a suffocating atmosphere of carbon dioxide and there is almost no water vapor; temperatures reach 462 degrees Celsius! But climate modeling suggested that ancient Venus might have had oceans and a model of dry land like ours. Several factors – including the water-land ratio, and the idea that clouds potentially protect Venus from strong sunlight – suggest that the planet may once have been habitable.

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

These rogue planets don’t orbit around a star, and so it’s pretty hard to spot them – in fact you don’t really know if there are any nearby. Statistically speaking, however, they are not close enough to be a problem and we really are a fairly small target given the size of the solar system.

According to Neil deGrasse Tyson, Dark Matter is the oldest unsolved mystery of modern astrophysics. In fact, he couldn’t either to be matter! Basically, the amount of gravity in the universe is not equal to the amount of observable mass – the planets, stars, galaxies, comets, black holes and dark clouds. So scientists propose that there is a large amount of unobservable or “dark” mass in the universe, which is the source of all that gravity.

This idea is based on a complicated theory known as vacuum decay – at the bottom a button of self-destruction for the universe! It’s only speculative at this point, but it’s about whether the universe is in a real or a false vacuum – a real vacuum is stable, but a false vacuum isn’t. If a random quantum fluctuation has allowed a fake vacuum to release its potential energy, it will create a real vacuum bubble that will expand at the speed of light and eliminate anything that has touched it. Destruction would be immediate and depending on where it happened in the universe, we could never see it coming. Remember, this is just a theory!

22.

And finally, this is not a fact per se, but have you considered the possibility that we have already sent a message to an alien race in the distant past and it is still making its way?

Space is huge, we’ve established it by now, and there’s every chance we already sent a message into space thousands of years ago and forgot about it (think about how societies change over time). We could even wait for the message to arrive, or wait for a response to travel through us. In that sense, we would only be constantly introducing ourselves repeatedly to what might be out there …
