9 planets, which may be alien life




# Gallery | 9 planets, which may be alien life March 14, 2013

At the end of last year, the so-called “catalog of potentially habitable planets» (Habitable Exoplanets Catalog) contained nine planets, which have the biggest chances to harbor alien life. Not all of these planets can be monitored and verified, and many scientists is to study the “habitable environment.” Perhaps three new giant telescope will help to see the bustle on the surface of exoplanets. In any case, you should definitely read these mysterious places. Suddenly, one of you will be able to go there and have a chat with the local inhabitants.

Here nine exoplanets, which may well be a life.

This planet – a controversial finding. It was opened in 2010, but has not yet been confirmed. However, the University of Puerto Rico at Arecibo believes that Gliese 581g – one of the best candidates for a container of alien organisms. This rocky world is at a distance of 20 light years from our Sun, and two to three times heavier than the Earth. Period of revolution around the star Gliese 581 in the constellation of Libra is about 30 days.

Another “super Earth», Gliese 667Cc, also located relatively close to Earth: only 22 light years to the constellation Scorpius. The planet is about 4.5 times the size of Earth and orbits the sun in 28 days. Star GJ 667C is a ternary system of stars. The fact that the binary (binary) systems more likely to create a potentially habitable zone, we wrote about recently . This star belongs to the class M dwarfs and weighs about one-third of the mass of the Earth Sun.

Although Kepler-22b of Earth, it orbits a star that is the size and temperature is very similar to our native sun. Kepler-22b is 2.4 times the size of Earth and is going through the greenhouse effect, which is similar to the Earth, that is, the surface temperature of the planet is 22 degrees Celsius. Its star system is 600 light-years away in the constellation Cygnus.
HD 40307g

This “super Earth” is conveniently located in the orbit in the habitable zone of potentially native star. It is located 42 light-years away in the constellation of the artist. It is so close that a good telescope can make out the details of what is going on her surface. Planet orbits its star at a distance of 90 million kilometers, which is slightly more than the distance from Earth to the Sun (150 million km).

HD 85512b introduced in 2011 as part of the treasure, which consists of the 50 planets discovered by HARPS precision telescope in Chile. The planet is about 3.6 times the mass of Earth and is about 35 light-years away in the constellation of Sail. Researchers hope to one day find water on its surface.

This planet, located near Tau Ceti, which is so like to write fiction, alluding to extraterrestrial life in this solar system, was discovered in December 2012 at a distance of 11.9 light years from Earth. This world is a “super Earth” at least 4.3 times the mass of Earth. Depending on the atmosphere, Tau Ceti e can be either warm the planet, suitable for living or dead hot as Venus.
Gliese 163c

gliese 163c

Mass of Gliese 163c assigns it to the planets in the “gray zone.” The planet is seven times the size of Earth, which is why it can be either a huge rocky planet or a gas dwarf. Gliese 163c is spinning around its dim star, making a complete revolution every 26 days. The parent star is located 50 light-years from Earth in the constellation Dorado.
Gliese 581d

At least one study suggests that Gliese 581d may have a thick layer of carbon dioxide in atmsofere. The planet is seven times the size of Earth and revolves around a red dwarf. The planet has another potentially habitable “sister» Gliese 581g. The distance to this star system – 20 light-years.
Tau Ceti f

Tau Ceti f – this is the same candidate in the inhabited worlds, as Tau Ceti e, but its orbit lies on the outside of the potentially habitable zone ranitse Tau Ceti. The planet is 6.6 times the mass of Earth and may be habitable if its atmosphere retains enough heat.

On whichever of these planets you settled? By the way, if you’re interested, not so long ago, scientists found the smallest exoplanet , but here it is in a potentially habitable zone or not, is unclear.

Higher intelligence recommends:

Found the smallest exoplanet
Approximately half of “suns” may have its “Earth”
Solve problems with communication repeaters
