A global catastrophe and we have to vacate the land. How long will it take to get to the most Earth like planets out of all that we have found to date? To begin with, the most Earth like planets of all detected is Kepler 452b.
Know about this planet, thanks to the space telescope Kepler, launched in March 2009 and who prey on the planet the last 5 years. Kepler 452 a star similar to the Sun, which is hurtling through space 1,400 light years from Earth. It should be noted that the star has the same surface temperature as that of our sun and almost the same energy output.
In general, as the sun, and Kepler 452 a yellow G-type dwarfs. This means that the Kepler 452 habitable zone the region around the star, which could theoretically exist, liquid water is almost identical to the sun. And interestingly, in the area around this star it revolves planet path which is almost identical to Earth, Kepler 452b. This planet takes almost the same place as the Earth in the solar system.

Land is an exception among the habitable planets in our galaxy: their chemical composition is totally different from the Earth. This is the conclusion the authors of an article in preprint arXiv. Brief research reports New Scientist. The Portuguese University of Porto and his colleagues studied the stars, the mass and the radius of which is different from the sun, and in the habitable zone of a planet there, where the water is present in liquid form. It was found that iron and other metals in the composition of these stars is less than that of the stars around which address only the uninhabited planet.
Since the planet’s chemical composition close to its star, the celestial bodies in the area of life is usually less metal than in the bowels of the Earth and the Sun, scientists have decided. As a rule, around the iron-rich stars are rotating massive rocky body, wrapped in a giant gasbag. Continue reading “Earth different from other planets in our galaxy”
Scientists for decades have been puzzled by the dissimilarity between the two sides of Mars. The northern hemisphere of the planet – a smooth and low – is one of the most smooth and level surface in the Solar System.
Potentially, it could be formed because of the water that once splashed on the Martian surface. At the same time, the southern half of Mars – all cut up rough and cratered. It is about 8.4 kilometers higher than the northern part. Continue reading “The biggest mysteries of Mars”
Twin Earth hid in the backyard, it may be only 13 light years from the solar system. This is the conclusion of scientists, you overestimate the size and temperature of a red dwarf, possible stars-hosts of planets.
Astronomers have chosen out of 158 thousand stars, Kepler Space Observatory, studied all red dwarfs, and then conducted a more precise estimate of their size and temperature. In most cases, the stars were colder and less than previously thought. Of the 95 tested red dwarf planets are 60% less of Neptune, and the three planets are similar to Earth.

The vast expanses of our galaxy located 17 billion planets that are comparable in size to the globe Earth and the Earth with almost a similar location in the star system. This was officially stated in the reports of scholars, astrophysicists from the American Center for Astrophysics at Harvard Smith.
“Our conclusions about the existence of 17 billion Earth-like planets are the results of analyzes of the data that came with a high-sensitivity NASA satellite, called” Kepler “- said today the British radio station correspondents” Bi-bi-si “, quoting astrophysicists Francois Fresina, that leads a group of scientists involved in this research.

Observatory “Kepler“, prepared with a powerful super-sensitive photometer can at the same time observe more than 100,000 stars, and will be watching them for 3.5 years. The presence of a planet near the star is determined by periodic changes in the brightness of the latter entailed by transit – the passage of a planet in front of a star.
The study and the “counting” of planets in our galaxy, attended by scientists from the California Institute of Technology Caltech.

A very believable and compelling reason to believe that in time we will find that life can be, even in our own planetary system. Here are seven reasons why scientists believe that life certainly exists somewhere and just waiting for meeting with us. Maybe it will not be green-skinned ladies in flying saucers, but it will still be aliens.
1. Extremophiles on Earth
A key question is, can exist and develop life in worlds radically different from Earth. It seems the answer is yes, if we think of the fact that even on this planet, there are extremophiles, or organisms that can survive in the extreme conditions of heat, cold, exposure to toxic (to us), chemicals, and even in a vacuum. Continue reading “Seven good reasons for which the other planets can be life”
Our galaxy is home to at billion of alien planets, and perhaps many more, a new study suggests. The Kepler-32 planets orbit an M dwarf, a type of star that is smaller and cooler than our sun. M dwarfs are the most common star in the Milky Way, accounting for about 75 percent of the galaxy’s 100 billion or so stars, researchers said.
Further, the five Kepler-32 worlds are similar in size to Earth and orbit quite close to their parent star, making them typical of the planets Kepler has spotted around other M dwarfs. So the Kepler-32 system should be representative of many of the galaxy’s planets, scientists said.

Press Secretary Pulkovo Astronomical Observatory Sergei Smirnov about what exactly will be 21 December 2012 in terms of astronomical events, we learn only when the date comes, and now it’s safe to say that there will be a small parade of planets. Let’s try to summarize the available evidence on this issue.
We are the closest to the edge of the galaxy. When looking at its center, we can see the constellation of Sagittarius and Scorpio. Dec. 21, the day of solstice, the sun passes through these constellations. We do not know how to line up the planets of other systems. This is wrong – do such forecasts, says Sergei Smirnov.
