The scientists have spotted more than 100 new potential alien planets, including one in the fourth-closest star system to the sun. The new study has confirmed the news.

According to NBC, after 20 years of data analysis, the astronomers have spotted newfound possible exoplanets. The analysis of the data was gathered by the HIRES (High-Resolution Echelle Spectrometer) instrument at the Keck Observatory in Hawaii.

The co-author of the University of California, Santa Cruz has stated that he was very happy to contribute to science that was fundamentally changing the view of us in the universe.

Space has stated that by using "radical velocity" HIRES detects exoplanets. This strategy is different from the employed by the most prolific planet hunter of all the time.

After the study, the astronomers have identified 60 so-called planets. They also got 54 others suggestive signals that require further investigation before they can be elevated to candidate status.

In the new study, the researchers have spotted official candidates' circles the star GJ 411, known as Lalande 21185, which lies just 8.3 light-years from the sun. Last August, the astronomers announced the discovery of a potential Earth-like world orbiting Proxima Centauri.

The scientific study of the research has stated that the possible GJ 411 planet is at least 3.8 times more massive than Earth and probably too hot to be habitable. The new planet lies quite close to the star, completing one orbit every 10 Earth days.

However, the huge HIRES data sets consist of nearly 61,000 measurements of more than 1,600 stars. The HIRES researchers have called the biggest compilation of radial-planet-hunting observation ever and they have also shared it with other exoplanets researchers around the world. The new research, which was led by Paul Butler of the Carnegie Institution for Science in Washington, D.C, was published in The Astronomical Journal.
