Astronomers were able to get pictures of the planet Tatooine amazingly similar to the saga of "Star Wars." Astronomers take pictures of the planet that resembles Tatooine from the saga "Star Wars" and the planet Solaris from the same product Stanisław Lem. The data are published on the website Phys.org.


Managed to find a planet with a telescope VLT, located at the observatory in Chile. Scientists from University of Joseph Fourier, compared the data obtained in 2002 and 2012, and concluded that the planet revolves around the two stars.

According to astronomers, it is hardly suitable for zhizni.Obekt 13 times the mass of Jupiter, in addition to the two stars it is 84 times (12.5 billion km) farther from the Sun than the Earth, writes The Atlantic.

The proximity of the stars of the celestial body system has allowed astronomers to conclude that the planet is made of gas. The fact that the possibilities of modern telescopes do not always allow one to classify these objects.

According to scientists, the gas giant was formed as a result of the gravitational instability in the orbit of the two stars. A system consisting of two red dwarfs, was originally surrounded by a cloud of dust and gas in which the mass distribution was uneven. Later, the cloud broke up into fragments, which are under the influence of gravity pulled together in a tight formation.

This contradicts the hypothesis of accretion, according to which the formation of the planet is due to the buildup of dust and small to larger particles. For this planet should be much further from the center of the star system.

In September 2011, using the Kepler space telescope has already found a planet that orbits around two stars at once. The size and weight it is approximately equal to Saturn and comprises gas. Complete revolution around its two suns, it makes for 229 days. The system Kepler-16 is located 200 light-years from Earth.

At the same time, scientists have suggested that there are conditions for the existence of life. The planet itself is hardly capable of harboring life: it reigns frost. But it is just a natural satellite is in the habitable zone, that is not too close and not too far from the star around which the planet rotates.

However, for this satellite to be a sufficient level of greenhouse gases such as carbon dioxide and methane. Then the climate is just right for the emergence of living organisms, scientists say. "The fact that the stars give enough light, so the moon itself to maintain the heat," — said Billy Kuorls, an astrophysicist at the University of Texas at Arlington.
