NASA Discusses Research Seeking Habitable Worlds Among The Stars
WASHINGTON, DC - JULY 14: (L-R) John Grunsfeld, astronaut and associate administrator of the Science Mission Directorate at NASA; John Mather, senior project scientist for the Webb telescope at NASA's Goddard Space Flight Center; Sara Seager, professor of planetary science and physics at the Massachusetts Institute of Technology; Dave Gallagher, director of astronomy and physics at NASA's Jet Propulsion Laboratory; and Matt Mountain, director of the Space Telescope Science Institute discuss 'the scientific and technological roadmap that will lead to the discovery of potentially habitable worlds among the stars' July 14, 2014 at NASA headquarters in Washington, DC. Most prominent among the methods NASA will search the universe for habitable exoplanets will be the deployment of the James Webb Space Telescope, with a mirror of 21 feet, scheduled to be launched in 2018.

The quest of Alien life has been taken into deeper research every day and astronomers have been successful in finding Exoplanets in the past. Recently they have spotted more than 100 new potential alien planets, these could possibly be Exoplanets as per a new study.

The recent discovery is yet to be confirmed as genuine alien worlds, but the possibilities are high as the information comes from a new analysis of 20 years worth data. This data has been gathered by the HIRES (High Resolution Echelle Spectrometer) an instrument at the Keck Observatory in Hawaii as per Space.

HIRES turned out to be an effective instrument to detect Exoplanets, it detects Exoplanets by using a "Radical Velocity" method by picking up the tiny gravitational wobbles, and its strategy is believed to be different from those employed by the most prolific planet hunter of all time.

Steve Vogt form the University of California, Santa Cruz stated that science is vitally changing how we view ourselves in the Universe. He has contributed, designed and built the HIRES. The data set of the HIRES is huge and it consists of nearly 61,000 measurements of more than 1,600 stars.

According to Long Room, in the new study researchers have identified 60 planet candidates. Along with this they have identified 54 other signals that need further investigation before they can be elevated to the candidate status. 

One of these official candidates circles the star GJ 411, which is also known as Lalande 21185. It lies just 8.3 light years away from the sun and only three star systems are closer. The Alpha Centauri is the only nearest system to the sun. Astronomers have also discovered Proxima Centauri, which is 4.22 light years away from the earth.

With constant research and instruments like the HIRES there are chances that out of the 100 possible Exoplanets Alien Worlds could exist.
