Are a new type of planets and dark alone?

U.S. astronomers discovered what they explain as a new class of planets: 10 dark bodies floating lonely far from any host star. The discovery was detected in the center of the Milky Way. The scientists, who published the findings in the journal Nature, believe these planets, which are the size of Jupiter, were expelled from their original planetary systems.

According to Professor David Bennett, professor of astrophysics and cosmology at the University of Notre Dame in Indiana,

Mars is still an "embryo" of planet

The planet Mars twisted in record time and reached its current size in just three million years, much faster than scientists thought. That rate of formation of the Red Planet could explain that its mass is one tenth of that of the Earth. The study supports a theory more than two decades, according to which the planet remained small because it avoided collisions with what would become the "planetary construction materials", ie other objects in space. The finding is published in the journal Nature.

In the early days of the solar system before the planets were formed, a cloud of gas and dust surrounding the Sun Scientists believe that the planets arose from the accumulation of this material driven by electrostatic energy.

The mysterious birthday Neptune

Neptune is approximately 4400 million kilometers away from Earth. Neptune is about to celebrate its first birthday. On July 12 will be a year-Neptunian-terrestrial or 164.79 years since its discovery on September 24, 1846. But why do we know so little about the distant planet?

At approximately 4400 million kilometers from Earth lies Neptune, the first planet in the solar system to be discovered deliberately. After classification of the planet Uranus in 1780, astronomers have been puzzled by his strange orbit. Scientists concluded that either Isaac Newton's laws had a fundamental flaw or something else-another-planet Uranus was pulling its expected orbit. And so began the search for the eighth planet.

Hubble finds out fourth moon of Pluto

 The Hubble Space Telescope exposed a fourth moon orbiting the planet Pluto, as NASA said.

The Hubble was looking rings around the planet, located in the outer edge of our solar system, when he came across P4, the temporary name has received newfound moon.

Mercury shows best kept secrets

Mercury place in foreign hidden craters, volcanic nature has an powerful, large amount of sulfur and convulses with energy blasts. These are the first findings of the data obtained by NASA's Messenger probe.

After nearly three months orbiting Mercury, this device has sent to Earth new data-with some surprises, on the composition of the Solar System planet closest to the Sun. The probe entered orbit around Mercury on March 18 and thus became the first spacecraft to achieve.

Discovery of a diamond planet

A new planet, made of a material alike to diamond ultradense, was discovered by a group of Australian scientists. It could be the most valuable rock sighted but never too far from the reach of explorer’s golddigger. At about 400,000 light years from Earth, the planet is located about one-eighth of the distance that separates us from the center of the Milky Way. Believed to be the only remnant of what was once a giant star in our own Milky Way.

That star, is now a pulsar, a type of neutron star characterized by very intense emit radiation, which was discovered in 2009. Its diameter is only 20 kilometers. Australian scientists found that the radiation was interrupted every two hours and 10 minutes, a sign that another celestial body orbiting around it. After observation with large telescopes in the UK and Hawaii (USA), discover the new planet.

Brightness

The planet appears to be smaller than Jupiter but has more mass. The scientists, who published their discovery in the journal Science, believe it is the densest planet ever discovered and composed mainly of carbon. Because it is so dense, scientists believe that carbon must be crystalline, so a large part of this exotic diamond planet would.

His theory is that high environmental pressure caused his core crystallized carbon into diamond. What is not clear is how she should look closely watched. Ben Stappers of the University of Manchester told Reuters that can only speculate: "I imagine that there would be a picture of a very shiny object."

Discovered a planet 36 light years away could harbor life

A planet with features that make it suitable for harboring life was discovered by a group of astronomers who used a powerful telescope in Chile. He has been called HD85512b and is about 36 light-years away. Its discovery by European astronomers announced a Monday and the scientific community considers it as already known planet other than Earth most likely to contain life.
