There is so much that we still don’t know about space, and every day we are learning new and surprising facts about the vast expanse beyond our planet. Here are just a few of the most surprising things we’ve learned about space in recent years:
1. There might be more water in space than on Earth.
We know that there is water on Earth, of course, but scientists have long suspected that there might be more water in space than on our planet. And recent research seems to support this theory. A study published in 2016 found that a large amount of water is present in the space between stars, and that there could be as much water in space as there is on Earth.
2. Dark matter makes up most of the matter in the universe.
We still don’t know what dark matter is, but we know that it makes up a large percentage of the matter in the universe. In fact, dark matter is thought to make up about 85% of the matter in the universe.
3. The universe is expanding faster than we thought.
The universe is expanding at an ever-accelerating rate, and scientists have recently discovered that this expansion is happening faster than they previously thought. This means that the universe is growing larger and larger every day, and is becoming increasingly difficult to understand.
4. There might be more planets in the universe than we thought.
Scientists have long believed that there are billions of planets in the universe, but recent research suggests that there might be even more planets out there than we thought. A study published in 2017 found that there could be as many as 10 billion planets in the Milky Way galaxy alone.
5. The universe is a lot older than we thought.
Scientists have long believed that the universe is around 14 billion years old, but recent research suggests that it might be a lot older than that. A study published in 2016 found that the universe could be as old as 20 billion years old, which means it’s been around for twice as long as we previously thought.

What is an interesting fact about space?
Space is vast and mysterious. While we have learned a great deal about it, there are still many secrets to be uncovered. Here are some interesting facts about space:
– Space is huge! There are an estimated 100 billion galaxies in the universe.
– Our sun is just one star in a galaxy of billions.
– The universe is estimated to be 14 billion years old.
– It is believed that the universe will continue to expand forever.
– Space is dark and cold. The average temperature in space is 3 Kelvin (–270 degrees Celsius).
– Space is filled with vast amounts of gas and dust.
– The universe is constantly expanding and evolving.

What is the most unique thing in space?
There are many things that make space unique, but one of the most fascinating is the vast array of celestial objects that can be found there. From asteroids and comets to planets and stars, space is home to an incredible diversity of objects. Each one is unique in its own way, and scientists are still discovering new objects all the time.
Another unique thing about space is its vastness. It’s hard to even comprehend just how big it is, and it’s growing all the time. Even the sun, which is one of the smallest objects in space, is huge compared to Earth. Space is also incredibly dark, making it a perfect place for astronomers to study the stars.
Finally, space is constantly in motion. The planets and stars are always orbiting around each other, and the universe is expanding. This means that the objects in space are always changing, and there’s always something new to explore.
What is the weirdest space fact?
There are many strange and weird things about space that still baffle scientists and researchers. However, if we had to choose one as the weirdest space fact, it would have to be the phenomenon known as dark matter.
Dark matter is a mysterious substance that makes up around 27% of the universe, yet scientists still know very little about it. They aren’t even sure what it is made of! All they know is that it doesn’t emit or reflect any light, hence the name.
One of the weirdest things about dark matter is that it doesn’t seem to obey the laws of gravity. Scientists have found that it affects the movement of galaxies and other celestial objects, even though it doesn’t interact with them in any other way.
There are many theories about what dark matter is, but no one knows for sure. Some scientists believe that it is made up of strange particles that we have yet to discover. Others think that it might be made up of black holes or other objects that we can’t see.
Whatever dark matter is, it is still one of the greatest mysteries of space. Scientists are working hard to figure out what it is and how it behaves, but so far they have had little success. So, the next time you are feeling weirded out by dark matter, remember that you are not alone!
Can you fart in space?
There’s a lot of things you can’t do in space, and farting is one of them.
At least, that’s what we thought. But in February of 2016, astronaut Tim Peake let one rip while aboard the International Space Station, and it turns out that you can fart in space – though it’s not necessarily a pleasant experience.
Peake’s noxious release was apparently caused by the combination of zero-gravity and a diet of mostly processed food. And while the sound of a fart in space is no different than it is on Earth, the smell is another story.
Since there’s no air in space, smells don’t travel, which means Peake’s fart smelled a lot worse than it would have on Earth. “I did a little experiment with my colleagues,” he said after the incident. “I released one into weightlessness and it drifted off into space. It was very, very unpleasant.”
So there you have it – you can fart in space, but it’s not exactly a pleasant experience.
Why is space silent?
The universe is a vast and mysterious place, and much of it remains unexplored. Even the space near Earth is largely a mystery. One question that has long puzzled scientists is why space is so silent.
There are a few theories about why space is so quiet. One possibility is that the vacuum of space doesn’t actually transmit sound waves. Another possibility is that the temperature of space is too low for sound waves to travel.
One of the most likely explanations is that the pressure of space is so low that sound waves can’t travel. The pressure of space is determined by the amount of matter and energy in an area. The more matter and energy there is, the higher the pressure.
Since space is largely empty, there is very little pressure in most areas. This means that sound waves can’t travel very far, and they eventually dissipate.
This doesn’t mean that space is completely silent. There are some sound waves that can travel in space, but they are very weak and difficult to detect.
There are a few exceptions to this rule. For example, if a spacecraft passes through the radiation belt around Earth, it can create a sonic boom.
Overall, space is a relatively quiet place. This doesn’t mean that it’s not worth exploring, though. There are still many mysteries to be uncovered, and who knows what we might find out there.
