Space is a strange place. He hides so many mysteries that he wants to figure out. Since the early days of space exploration, astronauts and scientists have discovered strange phenomena, from UFOs to mysterious lights. There are many stories circulating about strange things happening in the cold vacuum of space. What is it, why is it happening and how can it be explained?
Scientists are trying to find comprehensive answers to many of these questions. Curious? We will tell you about strange things happening in space.
Inexplicable knocking on a spaceship
Yang Liwei became the first Chinese astronaut and spent 21 hours aboard the Shenzhou 5 spacecraft. Liwei claims that he heard an incomprehensible noise, as if someone was knocking on the hull of the ship. He tried to figure out what could have caused this sound, but found nothing. There was no convincing explanation for this, but some believe it could have been the crackling of the ship's hull.
Space moray eels
NASA astronaut Story Musgrave claims that when he was in space, he saw moray-like objects moving on their own. They say he saw them twice. Most consider this to be space debris, but Musgrave remains unconvinced.

NASA started a fire on the ISS
Nobody wants to face a fire in a spaceship. However, NASA decided to deliberately set up a fire. It was an elaborate experiment to understand how fire behaves in space. As a result, it turned out that, firstly, the fire takes the form of a ball, and secondly, the flame reaches for the ventilation system, and does not just rise upward, as it happens on Earth. Scientists plan to continue experiments to find out how the fire spreads, at what speed, and what materials pose the greatest threat to astronauts.
The bacteria flew into space
Living organisms change after being in space, and bacteria are no exception. Researcher Cheryl Nickerson sent Salmonella bacteria into space for 11 days. After the bacteria returned to Earth, scientists infected a mouse with them to study the reaction. Usually a mouse infected with salmonella dies after 7 days, but an individual infected with space salmonella died two days earlier and from a lower dose. Similar experiments were carried out with other bacteria, but the result was always unpredictable and did not allow drawing a definite conclusion. It is still impossible to say exactly how microorganisms can change after a flight into space, and what effect these changes can have upon returning to Earth.
Strange moon music
As they flew over the dark side of the moon, the Apollo 10 astronauts heard what they called "space music." At that moment, they were just cut off from communication with the space center in Houston. The astronauts hadn't talked about it before, but a few years later, a low-frequency whistling noise was discovered on their audio recordings.
Aliens on the moon
You may be suspicious of this information, but it is said that Neil Armstrong sent NASA a secret message in which he claimed to have seen aliens. This message contained the text: "They are watching us from the dark side of the moon." However, it must be said that the astronaut himself never mentioned this anywhere and never.
Unexplained mysterious flashes of light
In 2007, scientists discovered mysterious flashes of light in space that lasted only a few milliseconds, they called them "fast radio flashes." Oddly enough, science really doesn't know what these outbreaks are and what causes them. A variety of theories have been put forward, including neutron stars, black holes, and even aliens.
Astronauts get taller
One of the weird effects of being in space for too long is that astronauts definitely get taller. Due to zero gravity, there is no such pressure on the spine, the astronauts straighten up and become taller by an average of 3%.
The Milky Way is a galaxy eater
With the help of the Hubble Space Telescope, NASA discovered a strange fact of galactic cannibalism in our home galaxy. Researchers studied 13 stars located in the outer halo of the Milky Way to understand how it was formed. They believe that over the course of its existence, the Milky Way has become larger, swallowing up small galaxies.
Giant water tank in space
At a distance of 12 billion light-years from us, there is a quasar containing a huge store of water, which exceeds the mass of water in the oceans of planet Earth by 140 trillion times. The very fact of detecting water in space is not unique; it is surprising and strange exactly the amount of water produced by a quasar.
Deformation of the eyeballs
Astronauts who have been in space for more than a month often ask doctors to have their eyes checked. A new study has shown that these people experience deformities in the eyeballs, optic nerves and lacrimal glands. Problems arise due to intracranial hypertension or, in simple terms, due to increased intracranial pressure.
The ninth planet of the solar system
Astronomers have found new evidence that the ninth planet, the size of Neptune, was once in the formation region of the planets of our solar system, but was then thrown into a distant elliptical orbit. Now it is so far away that it will take 15,000 years for it to complete one revolution around the sun.
UFO filmed
In March 1991, Russian cosmonaut Musa Manarov, while on the Mir space station, filmed a strange flying object on videotape. The capsule was very close, and a strange white object in the distance was clearly visible in the frame. The astronaut himself does not believe that this is space debris, as others say.
UFO live
During a live broadcast from the International Space Station on January 15, 2015, a strange flying object appeared in the frame. Just at the time of his appearance, NASA suddenly cut off the broadcast. What was this object, and why is NASA trying to hide it?
Astronauts lose bone mass
Talking about the consequences of a long stay in space, you can't immediately think of bones. However, in fact, astronauts who spend a long time in space lose bone mass. Bones are active living tissue and are healed by physical activity such as walking or running. In zero gravity, such activity is impossible, and the bones begin to weaken.
Live bacteria found outside the ISS
It was commonly believed that living organisms are unable to survive in the cold vacuum of space. However, astronauts recently discovered living bacteria outside the International Space Station. The bacteria were on the surface of the ISS; when such bacteria were launched, they were not there. Some began to argue that this is the first fact to confirm the existence of extraterrestrial life, but astronauts believe that there is a more plausible explanation. Upward air currents could carry bacteria into the upper atmosphere of the Earth, where they "stuck" to the surface of the ship.
