There are billions of super Earth in the Milky Way
The astronomers’ research indicates there are billions of Earth’s Super contained in the Milky Way. Super is the planet Earth with 1-10 times the mass of Earth. There are billions of super Earth in the Milky Way
The results obtained through detection and extrapolated to include planets around faint stars, called red dwarfs.
For detection, the team used Harps instrument at 3.6 meter telescope at La Silla Observatory, Chile. Harps detect planets by the gravitational influence of the planet on its star.
“Our recent observations with the Harps showed that 40 percent of red dwarf stars have a super-Earth in the habitable zone, where liquid water can exist on its surface,” said Xavier Bonfils of the Observatoire des Sciences de l’Univers de Grenoble, France.
“Because red dwarfs are very common, there are 160 billion in the Milky Way, it makes us conclude that there are tens of billions of planets like this (Super Earth) in our galaxy alone,” said Bonfils, who led the study, as quoted by the BBC on Wednesday (28/3 / 2012).

Bonfils and colleagues prior to the detection of Earth’s Super 102 red dwarf stars. Later, they found the planet Earth Super 9 with two of them located in the habitable zone.
The data are then processed by including the stars with no planets. The processed data will show how common planet Earth Super in a red dwarf star.
The results indicate that the data processing Super Earth in the habitable zone is found in 41 percent of cases, with a range between 28 and 95 percent.
According to astronomers, there are approximately 100 existing Super Earth in the habitable zone, at distances of less than 30 light years from its parent red dwarf star.
Then, is there life on planet Earth that Super?
Because red dwarfs frequent eruptions to send X-rays and ultraviolet, then the possibility of life on Earth Super the numerous small it seems.
Even so, researchers will continue to investigate the possibilities. They will look for signs of life molecules, such as oxygen. There are billions of super Earth in the Milky Way
