If ever people stay on Mars at least three years, they certainly have to survive the fall of a large meteorite hit and capacity of a megaton of TNT.
One obvious way to assess the chances of a future encounter with a meteorite impact - to look at the past. However, this task is not so simple, because the density and size of craters, survived for a long time, depending on many factors.

Vanishing of ships and aircraft in the Atlantic Ocean are due to methane gas that is released from the cracks of the antique plates. According to scientists gas turns into giant bubbles that reach the surface and "absorb" all that will meet them on the way.
Riddle of the Bermuda Triangle, "absorb" it gets into court, concerned mankind are more than half a century.
"On December 21, 2012, not the end of the world as we know it, however, is another winter solstice." That's how NASA denied the endless arguments about the "end of the world", and the reason is that I've heard of such a disaster have been so many that, in truth, not for science could not be so calm writing this article.
While we are on the eve of the expected December 21, I will make a top of the reasons why the world will not end, at least, in 2012, based on questions posed to NASA.
The awareness of sulfur dioxide in the dense atmosphere of Venus is more than a million times higher than that found on Earth. On our planet, almost all of this pungent and toxic gas comes from volcanic eruptions.
For this reason, it is thought that the detected sulfur dioxide in the upper atmosphere of Venus, well above its cloud cover, must have been recently pumped from lower bounds.

Approximate fifty leading experts on climate science in the world have studied the thaw out of polar ice, which is the main reason for the increase in water level in the oceans. Space satellites have helped researchers identify how decline in volume of glaciers in the Arctic, Greenland and Antarctica. It turned out that the glaciers are melting three times faster than a couple of decades ago.
The name "hobbit galaxies" ("hobbit galaxy") - this is quite a new term used to describe galaxies that are smaller and dimmer than the dwarf galaxies. By the number of stars that inhabit such galaxies (hundreds of thousands of stars), these objects occupy an intermediate position between dwarf galaxies and star clusters.

Quasars are very distant galaxies with extremely luminous core areas. Astronomers believe that massive black holes are the source of kvasarernes high energy show.
The supermassive black holes in quasars create such strong and very energy-rich effluents of material ejected and affect their surroundings. Astronomers have now found the most energetic outflows from a quasar ever.
Astronomers have discovered a giant black hole that is surprisingly heavy in relation to the galaxy hole live in. Super Heavy black holes in galaxies are typically several million times heavier than our Sun. But now, astronomers have found a black hole that is 17 billion times more massive than the Sun! The giant black hole at the heart of a galaxy called NGC the 1277th.

Spacecraft Cassini recorded an incredible storm that engulfed the famous hexagon on the north pole of Saturn. The diameter of the storm more than 30,000 kilometers.
Unique video probe sent to Earth on November 27, according to NASA. He had previously recorded storm in the northern part of the planet, but only in the infrared, because it was dark.
As they note, the image of the swirling vortex "cause illusory sense of rotation" of Saturn.
Astronomers believe that December 21, 2012 - the day that very mistrustful people waiting for the end of the world - will be the most common. According to them, the Sun will have no outbreaks, and will not even magnetic storms.
"Even the magnetic storms on that day will not be", - said the director of the Astronomical Observatory of Irkutsk State University Sergei Yazev.
According to him, Russian scientists from Irkutsk, Moscow and Novosibirsk watched a total solar eclipse on the northern coast of Australia.
In the north-west of Edinburgh, near Queensberry in the construction of a road bridge over the River Forth were discovered the remains of a prehistoric house built more than 10,000 years ago.
"The construction of the bridge, designed to facilitate the development of Scotland in the future, it helped to understand the past, "- says the opening of Scotland's Transport Minister Keith Brown.
The death of the world famous turtle named Lonesome George, the last of which was considered Abingdonskih elephant skulls, not to have disposed of its kind, as previously thought.
The researchers found that live on the Galapagos Islands, at least 17 turtles, which are similar to George genetic traits, including individuals of the same is kind to him.

Although Earth takes 365 days to complete its orbit, the newly discovered pulsar does PSRJ1311-3430 in just 93 minutes, making it the neutron star in a binary system with the shortest orbital period calculated to date. It is also the first discovery of a millisecond pulsar conducted through its gamma-ray emission.
The peculiarities of this new order they are listed in the journal Science.
How much water do you think there are on Earth? Approximately 70% of the surface of the Earth is covered by water, and oceans contain about 96.5% of all water from the planet. But there is water in the air as water vapor, in rivers and lakes, ice caps and glaciers, as moisture in the soil and groundwater, even in your body and your dog. However, all that water is in the "small" area of 1,385 km in diameter.
On December 31, the Gregorian calendar did something frightening. He spent the years 2011 to 2012. What we experience as the year came to an end? Earthquakes? Globally? A planetary collision? Stranger gravitational effects caused by an alignment with the galactic plane? Is the impact of a comet? 'Lighting' Earth?
As much as I wish it were true finally, it is likely that the New Year celebrations only involve a lot of alcohol and fireworks. It is the beginning of a new year for our calendar. Nothing more, nothing less.

Is December on the doorstep? Does this mean that awaits us last month of life on this planet, and whether a doomsday in 2012? We interviewed NASA scientists and their response surprised us. Read the article - it's interesting!
During the entire existence of mankind been countless theories about how our planet will cease to exist.
The Martian satellite Phobos could be the result of contact with Phobos debris ejected from the craters of the Red Planet during its bombardment by space objects, a new study indicates.
To explain the nature of the mysterious troughs are abundantly present on the surface of Phobos, in 2011, a group of American scientist John Murray has been proposed,
This finding sheds light on the formation of new planets. Mass of the new planet is 13 times greater than the mass of Jupiter, the largest planet of the solar and heavy systems. Previously, scientists doubt that the planet can be formed from a protoplanetary disk as massive stars, like Kappa Andromeda. To date, more than 800 planets discovered outside our solar system, but scientists have been able to photograph a few of them.

According to scientists, a single supernova explosion in the surrounding area can be radioactive titanium, the total weight of which can exceed 100 times the mass of our planet.
These new data, to dispose of the radioactive substance during a supernova explosion, it may give an explanation of the mysterious processes occurring inside stars just before they are followed by a catastrophic explosion and the release of elements from which the universe is almost everything, from the stars and planets and ending human .
This advanced technology is developed in the field of measurement, at the atomic level, the degree of change in ambient gravity , as well as for the detection of gravitational waves - ripples sort of space-time, which is caused by various events, including the Big Bang. According to the general theory of relativity, Albert Einstein created; gravitational waves are provided when massive cosmic bodies, during its motion, break the fabric of space and time.
Through the use of Hubble and Keck telescopes, astronomers have come to a rather startling conclusion about the nature, which is the process of change in the "blue" galaxies. Specifically, it relates to a process of change that takes place in these galaxies has for now as eight billion years - in other words, for the period, which is more than half the age of the universe.
Until now, it was assumed that the disk-shaped galaxy with a classic for these galaxies form, appeared in the universe, in its present form, about 8 billion years ago, and only slightly changed in all that time.
