Space is huge, and terrifying. Not just because we've barely scratched the surface of what lies beyond our blue green rock, but also because most of what we've discovered is beautiful beyond comprehension, and would kill us instantly and painfully. As if that's not enough, new horrific yet insanely cool things are being discovered and not understood daily. Here are 25 Of The Creepiest Things In The Known Universe to keep you up at night. 25 Of The Creepiest Things In The Known Universe | List25 Black holes are created when stars die. Meteors killed the Dinosaurs, and there's more where that came from! Random rogue planets. All gold on Earth came from outer space via meteors a long long time ago. She's not STILL in space, but for awhile, there was a terrified dog dying of stress and heat in space, in 1957. The Himiko Cloud is the largest object in the known universe, and it's basically a giant mystery blob of unknown origin that's half the size of our galaxy. Mars Some stars sing to themselves. Diamond Icebergs that float upon an ocean of carbon. Black holes move. Sometimes the moons of various planets are just as interesting as the planets they orbit. To clarify, we live in a Solar System, our sun (star) is called Sol, and our planets and their moons are grouped around our star. A giant cloud of Hydrogen Gas (Smith's Cloud) weighing as much as one million stars is headed towards our galaxy. Zombie stars come back to life by stealing material from neighboring stars. There's a giant hurricane like storm on Jupiter so big you could fit three Earths into it. Even with all the stars and galaxies and New York City Street lights that our solar system contains, there are still pockets of extreme blackness. There's a blue planet that rains molten glass because it's so close to it's sun that the temperature is nearly 2,000 degrees, because apparently every beautiful thing in space would kill you instantly. Dark Matter makes up about 80% of the mass in the universe, and we can't see it. In August of 1977 Ohio State University's Big Ear radio telescope received a signal from Deep Space, which became known as the "WOW!" signal, because that's what was written on the printout. The lowest note in the universe is a sound coming from a Black Hole. Aliens may have started talking to us in 2016. While scientists are looking at starting a colony on Mars (and this makes sense, as it's the next logical step in space colonization), the closest planet that would be inhabitable and similar to Earth is actually 20 light years away, and it's called Gliese 581g. When we see "shooting stars", what we're actually seeing is a meteor burning up in Earth's atmosphere. Dark Flow is not Dark Matter, it's somewhat more (sinister and) inexplicable.

Outside our protective magnetic sphere, space is a shooting gallery of solar radiation and cosmic rays that would wreak havoc on our bodies to a level that right now we can only speculate. And then there’s the 18 months you would spend on Mars, which doesn’t have a magnetosphere and a very thin atmosphere. Humans have never been exposed to this type of radiation for this long. It’s a problem we’ve never dealt with before, and it’s going to be a huge challenge to overcome. Number two: Extremely low air pressure. The Martian atmosphere has only 1% of the air pressure of Earth. Walking outside on Mars is not that much different from walking on the moon, from a life support systems perspective. The thin atmosphere is also a nightmare for landing on Mars. That’s why smaller rovers like Spirit and Opportunity used bizarre air bag systems to land and Curiosity, which was much heavier, had to use a combination of parachutes, thrusters, and a cable system to get there safely. So SpaceX’s vertical propulsive landing option is probably best for Mars, but this is something that’s never been done up to this point, so it’s hard to know what challenges there are in attempting this with the thinner atmosphere and lower gravity. Number 3: Perchlorates in the soil In the Biosphere 2 project, they grew their own food and struggled to have enough for everyone to eat. When they emerged at the end, many were malnourished and emaciated. In 2008, the Mars Phoenix lander found significant quantities of perchlorate in the Martian soil. Perchlorates are salt compounds that are often used in rocket propellants and they’re extremely harmful for humans. They interrupt the thyroid gland and prevent the body from absorbing iodine, which leads to aplastic anemia. That’s when your bone marrow can’t make new red blood cells. Red blood cells are what carry oxygen through the body. Minor problem. Or, if aplastic anemia isn’t your thing, you might get agranulocytosis, which prevents your body from making white blood cells. Chris McKay at the Ames Research Center said that if your backyard had this much perchlorate in the soil, it would be considered a superfund site. Basically Mars is a giant toxic waste dump. Number 4: The gravity problem Mars is smaller than Earth, with gravity only 38% of that you’re used to here. An average 150 pound person on Earth would weigh only 57 pounds on Mars. We do have some idea of what to expect from long-term zero gravity thanks to astronauts like Scott Kelly and Mikhail Kornienko, who just this year completed a year-long space mission. Although the record was set in 1995 by Valery Polyakov, who flew on the Mir space station for 437 days. And last but not least, number 5: The Contamination Problem We’ve talked in videos about the Fermi Paradox and the Drake Equation in the search for intelligent life in the universe. Because if life could form twice in one solar system, the potential for life in other solar systems, and intelligent life, becomes very significant. So one of the biggest problems when it comes to traveling to Mars is that we’re not just bringing ourselves… We’re bringing our microbes. The second we land on Mars, we have contaminated it.
Some ancient artifacts and relics are so advanced, we can't place them in history... they shouldn't exist! The origins and purpose of artifacts are still disputed.

Which means that there would be an actual edge of the Universe. What happens at that edge? Is there a restaurant? Join Matt on this week’s episode of Space Time as he explores the greatest expanses of our Universe. So what do you find when you reach the edge? More Universe? Bubble Universes?

As brave space explorers, astronauts have to tolerate their bones weakening and their eyes changing but no one expected they would see ghostly lights or hear otherworldly music in space. Even stranger is the chilling stories of exploding objects, space eels, and strange spacecraft caught on NASA footage. These NASA secrets are just as weird as the things astronauts did on purpose, like bringing contagious bacteria into space and turning it into super bacteria or lighting a fire to see what burned. Of course, who can forget the strange UFOs caught on camera in space. See all these and more in this video of 25 strange things that have happened in space.
