					6 most "scary" cosmic phenomena
Space is full of weird and even scary phenomena, ranging from stars that suck the life out
of their own kind and ending with giant black holes are billions of times larger and more
massive than our Sun.
                                      1. Planet Ghost

Many astronomers say that the huge planet Fomalhaut in sunk into oblivion, but it seems
to be alive again.
In 2008, astronomers using the Hubble Space Telescope, NASA announced the discovery
of a huge planet that revolves around a very bright star Fomalhaut, located at a distance of
only 25 light years from Earth.Other researchers later questioned this finding, stating that
the scientists actually found a huge cloud of dust.
However, recent data obtained with the Hubble, the planet is found again and again. Other
experts scrutinize the system surrounding the star, so the planet of zombies may be buried
more than once before on this issue will make a final verdict.
                                       2. Star-zombies

Some stars will literally come to life cruel and dramatic fashion. Astronomers classify these
stars as a zombie SNe Ia, which generate huge and powerful explosions that send
"innards" of stars in the universe.
Type Ia supernovae explode binary systems, which consist of at least one white dwarf - a
tiny ultra-dense star, has ceased to pass through the nuclear fusion reaction. White dwarfs
'dead', but in this form they can not remain in the binary system.
They may come back to life, albeit briefly, in a huge explosion with a supernova, sucking
the life out of its companion star or by merging with it.

                                       3. Star-vampires
Just like the vampires of fiction, some stars manage to stay young by sucking the life force
of the unfortunate victims. These stars are vampires known as "blue stragglers", and "look"
they are much younger than their neighbors, with whom they were rendered.
When they blast temperature is much higher and the color is "much bluer." Scientists
believe that this is the case, because they suck a lot of hydrogen from nearby stars.

                                   4. Giant black holes

Black holes can show the object of science fiction - they are extremely dense, and gravity
in them is so strong that even light can not escape from them if coming close enough.
But it is very real objects, which are quite common throughout the universe. In fact,
astronomers believe that supermassive black holes at the center of most (if not all) of
galaxies, including our own Milky Way.Supermassive black holes Astounding in size.
                                   5. Killer Asteroids

In the previous paragraph phenomena can be scary or take the abstract form, but they do
not pose a threat to mankind. What can be said about large asteroids that pass close to
the                 Earth                  at                 a                  distance.
asteroid even as small as 40 meters can cause serious harm if he gets into town. Likely
impact of the asteroid is one of the factors that have changed life on Earth. It is assumed
that 65 million years ago it was an asteroid killed the dinosaurs. Fortunately, there are
ways to redirect dangerous space rocks out of the ground, if, of course, able to detect
                                       6. Active sun

The sun gives us life, but our star is not always so good. From time to time it occurs with
serious storms that could potentially devastating effect on radio communications, satellite
navigation and operation of power grids.
Recently, these solar flares are most often observed, because the sun entered its active
phase in particular the 11-year cycle. The researchers expect that solar activity will reach
its peak in May 2013 the first year.
