The picture below covers a distance of 50 light-years.

Each of those dots in the picture above is a star, like our Sun. The distance across our Sun is 864,000 miles, which is 109 times wider than Earth. Think of all that...space.

There might be another planet on the rim of our solar system.

Some astronomers have found evidence of a ninth planet far beyond Neptune (I'm sorry to those of you who are still sore about the whole "Pluto isn't a planet" thing). Although it has yet to be observed, the astronomers have noticed strange orbital patterns of smaller objects in the Kuiper Belt.

have you considered the possibility that we've already 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 established that by now, and there's every chance we've already sent a message into space thousands of years ago and forgotten about it (think about how societies change over time). We could either still be waiting for that message to arrive, OR waiting on a reply to travel back to us. In that sense, we would just be constantly introducing ourselves over and over again to whoever else might be out there....

According to quantum mechanics, there's a small chance the entire universe could spontaneously disappear and never come back.

This idea is based on a complicated theory known as vacuum decay – basically a self-destruct button for the universe! It's only speculative at this point, but it comes down to whether the universe is in a true or a false vacuum – a true vacuum is stable, but a false vaccum isn't. If a random quantum fluctuation allowed a false vaccum to release its potential energy, it would create a bubble of true vacuum that would expand at the speed of light and delete every single thing it touched. Destruction would be instant and depending on where it happened in the universe, we might never see it coming. Remember, this one is just a theory!

Dark Matter is believed to be responsible for 85% of gravity in the universe, and no one knows what it is or how it works.

According to Neil deGrasse Tyson, Dark Matter is the longest-standing unsolved mystery in modern astrophysics. Indeed, it might not even be matter! Basically, the amount of gravity in the universe doesn't quite equal the amount of observable mass – the planets, the stars, the galaxies, the comets, the black holes, and the dark clouds. So scientists propose there is a large measure of unobservable or "dark" mass in the universe, which is the source of all that gravity.

There are rogue planets that have been knocked out of orbit just chilling out in the universe, and they could do the same to another planet.

These rogue planets do not orbit a star, and so it's pretty hard to glimpse them – in fact we don't actually know if there are any nearby at all. Statistically speaking, however, they are not close enough to be a concern and really we're a pretty small target given the size of the solar system.

It's possible for two pieces of the same metal to actually fuse together if they touch in outer space.

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 join together. This doesn't happen on Earth because there is always air or water separating the pieces.

Venus looked pretty much exactly like Earth does now around two billion years ago.

Venus today is a living hell. It has a suffocating carbon dioxide atmosphere and there is almost no water vapour; temperatures there reach 462 degrees celsius! But climate modelling has suggested that ancient Venus may have had oceans and a dry land pattern just like ours. Various factors – including the water to land ratio, and the idea that clouds potentially shielded Venus from strong sunlight – suggest that the planet may once have been habitable.

The Voyager 1 spacecraft will likely outlive planet Earth itself.

The probe was launched back in 1977 in order to study Jupiter and Saturn and is now on its second mission out of the solar system. It will now drift through interstellar space forever. The Earth will probably be vaporised by the sun in a few billion years, meanwhile Voyager 1 will probably still be moving through space.

It's also true that, on average, a bit of debris crashes back to Earth about once a week.

It's mostly larger satellites that have survived the fiery reentry process and, truth be told, they more often than not land in the ocean (ugh) or in some remote area. There is a whole team of researchers dedicated to tracking space debris and monitoring its risk of colliding with Earth – as far as we know, no one has died by being struck by a bit of old satellite!

There's a rogue supermassive black hole speeding through space at around five million miles per hour.

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

So we know that light takes a long time to travel through space, right? Well, there are actually some parts of the universe we can't see because the light from there hasn't reached us yet.

The universe is so extraordinarily vast that light from these galaxies, which were formed during THE BIG BANG, still hasn't gotten to us!

There is a planet in our galaxy where the temperature during the day can reach over 1,000 degrees celsius and it possibly rains molten glass horizontally at around 4,500 mph!

The planet, known as HD 189733b, was spotted using NASA's Hubble Space Telescope and is a cobalt blue colour.

But here's the thing, there is such a phenomenon as The Kessler Effect, in which a single destructive event in Earth's low orbit could cause all satellites to break up into smaller and smaller fragments until the planet is surrounded by a massive cloud of shrapnel.

This would make ever having to leave Earth almost impossible.
