Scientists Believed Super-Earth Planets Support Alien Life

Scientists found Gliese 411b along with 60 new extrasolar planets orbiting stars close to Earth's Solar System.

Research by a team of global scientists has found 54 potential planets. Gliese 411b has been labeled a "Super Earth", which means that it's a rocky planet much like our own. Super-Earth Gliese 411-B claimed can support the humanity, the hot exoplanet is the 4 nearest to the solar system and has a rocky surface. Gliese 411 and its orbiting planets are just eight light years from Earth, putting them right in our celestial backyard, but despite is relative proximity to our own planet, the star is still about six trillion miles away, so it's unlikely we'll be stopping by any time soon.

The US astronomers spent 20 years and used the Keck-I telescope to collect the results of the observations.

Over the course of the 20 year survey, researchers obtained nearly 61,000 observations of 1,600 stars, according to a statement The Carnegie Institution of Science. "We were very conservative in this paper about what counts as an exo-planet candidate and what does not, and even with our stringent criteria, we found over 100 new likely planet candidates", Mikko Tuomi of the University of Hertfordshire in the United Kingdom said.

But astronomers did not believe it 5 years ago, but now they believe it.

"These new planets also help us better understand the formation processes of planetary systems and provide interesting targets for future efforts to image the planets directly", said Dr. Tuomi, the only European based researcher working on the project.

"The work of this team and their willingness to share data and techniques unveils a world of new possibilities, vastly increasing the ability of astronomers everywhere to perform in-depth studies of these exoplanet systems", said Hilton Lewis, director of the Keck Observatory.

For the first time the Lick-Carnegie Exoplanet Survey started in 1996 by Steve Vogt and Geoffrey Marcy, two famous astronomers from the University of California and Paul Butler, from the Carnegie Institute of Science, in Washington.

Using this information the scientists were able to track tiny colour changes in stars, which revealed the existence of planets. This radial velocity method searches stars for signs of gravitational wobbles induced by orbiting planets. "Over recent years it is found that there are more planets in the Universe than the stars".
