The most frightening 'monsters' in the universe

The universe is full of bizarre, frightening phenomena, from stars that can drain your life to the giant black holes that are billions of times more massive than our Sun.

'Death come back' planet

Fomalhaut b is a giant planet once observed by many astronomers to be dead and broken into cosmic dust, but recently there are signs that it is resurrecting.

In 2008, astronomers used the Hubble space telescope of the US Aerospace Agency (NASA) to claim to have discovered a giant planet orbiting a bright star Fomalhaut, located only 25 meters from Earth. light year. Other researchers later expressed skepticism about the planet named Fomalhaut b, citing the reason that the discovery team actually envisioned a giant cloud of dust.

However, a new analysis of Hubble's observations from 2004 - 2006, is expected to be published tomorrow in the Astrophysical Journal Letters, rediscovering the planet Fomalhaut b. Again, many other researchers are denying the existence of this planet.

The case like the planet Fomalhaut b is called the "zombie living" planet, died but then resurrected although not completely as it was originally. Astronomers view the living zombie planets as type Ia supernovae - large, powerful explosions that shoot components inside the stellar star into the universe.

Type Ia supernovae exploded from some binary star system, which contained at least one white dwarf - a tiny super-massive star that stopped experiencing nuclear fusion reactions. White dwarfs are in a 'dead' state but are not always the same in the binary star system. They can be revived, though very briefly, in a giant supernova explosion by sucking matter from a companion star or mixing with it.

Vampire stars

Like vampires in fiction, some stars in the universe have found a way to 'stay young and old' by drawing away the life force of unfortunate victims. These vampire stars are also known as 'blue wandering guys' and they behave much younger than older neighbors formed at the same time. For example, they burn hotter and seem to be greener.

Scientists claim that vampire stars exist so by draining hydrogen fuel from their companion stars.

Huge black holes

In astronomy, a black hole or a black hole is defined as a region in space that has such gravity that it does not allow any form of matter, including light, to escape its boundary, except for the possibility of material loss from black holes thanks to quantum tunnel effect. In other words, black holes can swallow everything close enough.

In the universe there are countless black holes. In fact, astronomers believe that the supermassive black holes are at the center of most (if not all) galaxies, including our Long Galaxy. Recently, researchers have discovered two black holes capable of containing the mass of 10 billion suns.

The unspeakable dark array of the universe

If you are afraid of the dark, the deep part of the universe is not the place for you. It was an extremely dark place, far away from all the light.

According to scientists, the universe is black because they are so amazingly empty. Although trillions of stars are scattered throughout the universe, the huge spaces between them do not have many molecules to reflect and spread light.

Witch's weapon

In the space full of things with strange shapes like glittering skulls, wicked eyes of witches, . We see all these shapes in the diffusion of sparkling gases and dust, Known as nebulae scattered throughout the universe. Pareidolia, a psycho-social psychological phenomenon, makes us see familiar objects in random shapes. Observing that witches' spiders or brooms in space are just one example of pareidolia syndrome, a psycho-social psychoanalysis phenomenon, we see familiar objects in random shapes.

Assassin asteroids

Experts say a mass of meteorite at least 1km wide can erase human civilization if it collides with our planet. And even asteroids only 40 meters across can cause serious local scale damage if they encounter Earth at a point near a densely populated residential area.

Collisions with asteroids have occurred with the Earth. For example, scientists identified a 10-kilometer block of meteorites that extinct the entire dinosaurs on Earth when it crashed into our planet 65 million years ago. Fortunately, today, scientists around the world constantly monitor dangerous meteor masses in the universe and devise ways to deflect the asteroid that is bombarding the Earth.

The sun is in its most active state

The sun gives life to the Earth but it is not quite benevolent. The sun occasionally releases storms from giants, potentially damaging the communications systems, satellite navigation and the power grid on Earth.

Such outbreaks of the sun have increased recently when this star entered a particularly active period of his 11-year cycle. Researchers speculate, the sun's activity will peak in 2013.
