Are Aliens Real? 60 new planets found on galactic doorstep

One of the exoplanets, described as a hot "super Earth" has a rocky surface and is found in the fourth-nearest star system to ours.

Dr Tuomi, led the analysis of the data, he said: "It is fascinating to think that when we look at the nearest stars, all of them appear to have planets orbiting them".

Of the new planets discovered, researchers say that one - Gliese 411b - stands out.

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.

The planets were discovered based on observations, which were taken over 20 years by USA astronomers who used the Keck-I telescope in Hawaii as part of the Lick-Carnegie Exoplanet Survey, according to the statement.

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. "Over the recent years it has been established as a scientific fact that there are more planets in the Universe than there are stars".

But astronomers did not believe it 5 years ago, but now they believe it. It represents a good chunk of my life's work'. USA Today reported that with the help of Hawaii's Keck-I telescope, Butler stated that their discovery was a crowning glory as an astronomer as the newly discovered planets further understands and enhances the processes in planetary formations and for the effortless imaging planets in the future.

Dr Tuomi added: 'Keck-I telescope and its instruments have been wonderful tools in establishing the current consensus that virtually all stars have planets orbiting them.

The group's results were based on measuring small periodic changes in the target stars' colours, indirectly revealing the existences of the planets.

The research team discovered the planets with the iodine cell radial velocity technique.

The means it orbits its star (Proxima Centauri) at a similar distance that the Earth orbits the Sun, possibly offering all the ingredients for life.

Another aim of the astronomers was to democratise the search for planets. It is by blazing a mixture of organic molecule to point and identify amino acids, and in detecting a remote planet's habitability and NASA recently developed a new model.
