10 scary things about space



Since the dawn of man (and woman) mankind has been staring at the flickering stars high in the search for meaning, guidance and inspiration. A gradual advance in science and technology has taught us a lot about our distant skies – that it's cold, dark, and torturously mysterious up there. It's also scarier than hell.

Nonetheless, it's hard not to dream beyond the outer limits or just to laugh at Kirk Kirk and this space lizard in the worst combat scene ever filmed. Though many elements of the last frontier are elusive, recent discoveries have revealed a series of frightening threats that will make even the bravest star warriors hide under blankets at night.

0th Meteor Shower

Imagine driving your Honda or Chevy GUV (Galactic Utility Vehicle) on the old satellite when suddenly firing out of nowhere – BLAMMO – You are blindly hit by a huge boulder , Your insurance premium not only skyrockets, but the next space-based support is billions of miles away. Crap.

Although this scenario seems like a sci-fi nightmare, in 2013 a similar event occurred on Earth after a meteorite exploded over the Ural Mountains in Russia . When the dust had settled, more than 400 people had been injured, highlighting the disturbing reality with which cascading rubble can strike without warning.

Fortunately, most of the large falling objects burn while traveling through the Earth's atmosphere. However, space travelers will have to resort to a number of other potential threats, including meteorites, comets and asteroids .

. 9 Black holes

Q: What captures light, spins time and works on a colossal scale, but can not be seen? A: black holes . For its enigmatic sake, black holes were mythically confusing since Albert Einstein first introduced the term in 1916 with his Theory of General Relativity.

Astronomers recently acquired the image of a black hole over the Event Horizon Telescope, a network of eight interlinked telescopes around the world. Although many questions remain unanswered, black holes are characterized by their influence on nearby debris, stars, and galaxies – and are usually formed by the death of a large star known as a supernova (more on that later). Unlike a planet or star, a black hole has no surface but occupies a region where matter has collapsed. The amount of concentrated mass is such that nothing can escape its attraction – not even light – and certainly not an astronaut making a devastating wrong turn while lost in space.

Black holes come in many different sizes. Similar to tornadoes, they move at high speeds leaving a trail of destruction. Even a small one in our solar system would be catastrophic, throw planets out of orbit and tear the sun to pieces. Although intrepid explorers will be tempted to visit these dark cavities, nothing has yet survived a trip to a black hole.

. 8 Solar flares

Our sun is a glorious, awesome star that provides warmth, light and the necessary temperature for precious life to exist. It is also growing steadily – and will someday completely destroy the Earth and burn down our beloved planet like a marshmallow that lay too long by the campfire. Fortunately, this does not happen for billions of years, but in the meantime, solar flares can cause tremendous damage with little or no warning.

A Solar Flare is a violent outbreak. This occurs when stored energy in the sun is suddenly released. This creates another of those ridiculously hotter numbers than hell, which triggers a burst of radiation across the electromagnetic spectrum.

Scientists classify solar flares according to their brightness and x-ray wavelengths. The biggest categories of X-Class Flares are big, disruptive events that can severely damage satellites, wipe out power grids, and dump all "smart" technology into stupid shit.

. 7 Eridanus Supervoid

First and foremost, stop your juvenile giggle. No, that's no slang for an epic bowel movement or something else. It is believed that the Eridanus Supervoid is a massive, empty section located in the Eridanus Constellation south of Orion. The intriguing thing about this discovery, however, is that it's not just the largest structure ever seen in the Universe, but that about 10,000 galaxies are missing – or about 20 percent less matter than in other regions. As a result, the curiosity may possibly contain an "alternative reality" within this menacing sky.

In 2004, cosmologists at the University of Hawaii observed a span of 1.8 billion light-years at a distance of about 3 billion light-years (1 light-year = 5.88 trillion miles). They identified a large cold spot on the Cosmic Microwave Background (CMB), a map of the radiation left over from the Big Bang, which is an important tool to study the origin and evolution of the Universe in cosmic timescales.

The startling revelation posed a puzzling puzzle: the size of the cold spot does not match our current understanding of the evolution of the universe. While it is not uncommon to find a few small hot and cold spots on the CMB, cold spots of this size are a scratchy anomaly. According to a report it is "too big to exist".

. 6 Fermi's paradox

In 1942, an Italian-American physicist named Enrico Fermi led an all-star team of scientists to build the world's first nuclear reactor. This monumental effort was part of the Manhattan Project a top-secret US government operation that produced the atomic bomb. Thereafter, Fermi shifted his attention and extraordinary ingenuity in solving another complex issue: Why did not we discover another alien civilization, despite the billions of billions of other Earth-like planets most likely to exist?

The theory known as " Fermi's Paradox, " postulates that the high likelihood of extraterrestrial life contradicts the lack of fact-based demonstrable evidence that supports this. Of course, this school of thought does not take into account the countless claims made by people who allegedly experienced UFOs or extraterrestrial encounters – not to mention phenomena like Crop Circles and Cargo Cult Theory .

Although it's hard to argue with a genius of Fermi's stature (especially our own limited reptilian brain), the question remains whether it's more frightening that we're all alone or hostile life forms are waiting for us like Devouring a Great White Shark eating seal snacks. In any case, it is best to leave the above-mentioned light on at night.

. 5 HyperNova

Many subjects who deal with the cosmos refer to an unattainable number. A hypernova is one of them. In this case, the astronomical figure refers to the excessive amount of heat and energy generated by an explosion. But first let's take a look at what's known about these fascinating wonders.

Novas are relatively small outbreaks that occur in binary systems. When the gravity of a white dwarf pulls material away from a companion star, gas rises and eventually becomes so dense that it ignites in a spark of nuclear fusion. Next, the supernova usually marks the death of a large star and the formation of a neutron star. The heat of a supernova can reach 120 million degrees – a temperature five times higher than a nuclear attack.

Finally, a hypernova is an ultra-energetic supernova that marks the birth of black holes and the release of intense intensity [19659004] Gamma-Ray Bursts (GRBs), the most energetic form of light. The most powerful of the Nova family, hypernovae are 5 to 50 times more energetic than a supernova. To complete it is " Champagne Supernova " a song of the megapop band Oasis, whose text the scientists can not yet decipher.

. 4 We are really, really, really small …

Although Mother Earth appears to be a gigantic sphere of bottomless oceans and endless roads, we are relatively puny compared to other planets. How small? Jupiter is 2.5 times larger than all other planets in the solar system combined. But if you really want to feel tiny, look no further than our sun – this big, fiery 10,000 degree Inferno at a distance of 93 million kilometers.

The diameter of the sun is 109 times larger than the rock we call home, and is so large that it could accommodate 1,300,000 planet earths. While the glowing ball seems to be the biggest star in the sky, this is just because it's the next one. The # 1 star in the universe is the gigantic UY Scuti a red Supergiant with a radius about 1,700 times larger than our Sun.

But do not despair, earthlings. At least you now know how a ladybird feels on a thin blade of grass.

. 3 Rogue Planets

These roaming vagabonds (also known as nomadic planets, unbound planets, orphaned planets, starless planets, etc.) are objects of sufficient mass to qualify as planets, but directly orbiting a galactic center. The universe, despite its vastness, is a packed arena, often reminiscent of a well-choreographed dance. But one rogue planet interrupts this river and ruthlessly stumbles to the rhythm of its own rhythmic buzz as it bumps against other cosmic bodies like a drunken ballerina.

Scientists believe that rogue planets may have been ejected from an earlier planetary system or were never gravity bound to another body like a star. In addition, our galaxy (aka the Milky Way) alone may have billion

. Interestingly, some rogue planets have a molten core that combines with an isolated core, cold exterior, could have subterranean oceans that support life. A team of Rice University petrologists has recently come up with the theory that a rogue planet the size of Mars may have collided with Earth 4.4 billion years ago and could have planted the seed of life while creating enough debris that later became our moon

2. Space debris

Since the beginning of the space race man-made objects are piling up in what is politely called "orbital debris". This is a bit too friendly. Let's just call it the way it really is: space debris . With a wide range of waste, there are now thousands of metal fragments, cameras, rocket boosters and even a complete US satellite (Vanguard-1) from 1958, currently the oldest man-made metal pile still in orbit.

This overflowing galactic garbage, not unlike our polluted oceans, is rapidly approaching a critical point; The consequences could be detrimental to astronauts as well as to those taking cover from falling garbage. There are currently over 1,700 satellites in operation, but less than 10 percent of the debris is large enough to be tracked from the ground. An obscene number of smaller objects can also cause serious damage – and unfortunately, the number just continues to increase.

In just one action in 2007 China destroyed a decommissioned weather satellite during one of its weapons tests and destroyed the object in over 150,000 pieces. Any attempt to clean up the spiraling chaos, however, could cause even more problems with regard to national security (surveillance equipment) and / or conflicts over territorial rights. In short, we are doomed to fail.

. 1 Zombie Stars

Just when you think we can not flood more movies, TV shows and books about bloodsuckers and the undead, the science community has come up with " Zombie Stars [19659004“angeschlossen]." "Yes, really? [194559004]

No matter.

A zombie star is something that will not die. "The monstrous explosion of a supernova typically glows brightly for a while before the monster's explosion That is, if the star can avoid death for reasons to be determined In addition to the horror show, the zombie star may become a vampire star by sending fuel and energy from a nearby star sucks to revive itself.

The most famous zombie (for scientists anyway) is known as iPTF14hls The star appeared too He first met in 1954 and was believed to have died over half a century ago – but a discovery from 2014 revealed that he is still alive and has no plans for retirement. According to the well-known astronomer Iair Arcavi a NASA postdoctoral fellow at the University of California at Santa Barbara (UCSB) and the Las Cumbres Observatory, the star's inexplicable behavior is "the biggest puzzle I've ever encountered encountered. "

Yikes. If he's baffled, folks, all we can do is close the doors to the space station and hope for the best.
