Super-Earth Discovered Orbiting Several Suns

Last Updated on

MessageToEagle.com – Scientists at the University of Goettingen and the Carnegie Institution for Science in the U.S. Washington have discovered a potentially habitable planet, located 22 light years away from Earth.
The super-Earth, named GJ 667Cc has the mass four and a half times that of our Earth and an orbit of 28.15 days.

The planet GJ 667Cc orbits a dwarf star of the class M, 22 light years away which corresponds to approximately 209 trillion kilometers.

“These super-earth are good choice for the existence of liquid water and life, as it also occurs on Earth, “says one of the lead investigator, Dr. Guillem Anglada-Escudé from the University of Goettingen, Germany.

“Our discovery shows that habitable planets may result in more different environments than previously thought,” said Dr. Anglada-Escudé.

The super-Earth receives from the dwarf stars they orbit, about one-tenth less light than our earth from the sun.

Since a large part of this light is in the infrared range, the planet can accommodate about as much energy as our earth.

The dwarf star has, in contrast to our sun barely metallic elements.

“With a new generation of measuring instruments such scientists could dwarf stars systematically investigate similar research on this planet now and again targeted for spectroscopic signs of life.”

The blue and turquoise area in which the newly discovered super-Earth (planet c) is provides good conditions for the existence of liquid water. The already well-known super-Earth (planet b) is too close to the dwarf star and is too hot. Possibly exists another super-Earth (planet d), but which is probably removed too far.

The researchers found the new super-Earth, as they wanted to explore a different super-Earth in the same star system. In their study, they analyzed data using a new method of the European Southern Observatory (ESO) and the Magellan II telescope in Chile and the Keck Observatory in Hawaii. In future studies, the scientists want to find out whether there are in the star system a so-called gas giant and another super-Earth.
The scientists have published their research results on the Internet at arxiv.org. These discoveries will soon appear in the journal The Astrophysical Journal Letters.
