. The discoverers of the planet from Proxima Centauri began to search for the full analogues of the Earth closest to us bodies of small size – Barnard’s star, Ross 154 and the second planet from Proxima Centauri, the press service of the Queen Mary University in London.

«The search for analogues of the Earth the nearest to us stars in itself interesting for us, and we want to use them in order to show the public how science works, and to enlist volunteers to analyze data,» said Guillem Anglada-Escude (Guillem Anglada-Escude) of Queen Mary University. To look for new planets to be in data collected over 100 days of continuous observations of stars. «We will conduct the experiment in the experiment,» — said Anglada-Escude.

A year ago, Anglada-Escude and his colleagues are authors of a surprising discovery – they were able to detect small earth-like planet from Proxima Centauri, a red dwarf of the triple alpha Centauri system and our nearest star.

Initially, the researchers thought that b Proxima — our nearest rocky planet most similar to Earth. Today, many planetary scientists believe that life on it is impossible because of the hectic nature of red dwarf: its surface is constantly having flash that can «tear off» with the planet’s atmosphere.

The researchers wondered if there are similar planets and others closest to us stars, most of which are red dwarfs — stars Barnard, removed from Earth, only 6 light years, and Ross 154, located about 10 light years from the Solar system.

To find these planets, scientists have created the project Pale Red Dot, so named by analogy with the obtained probe «Voyager-1» in 1990 from a distance of six billion kilometers a photograph of the Earth, which the great astronomer Carl Sagan in one of his public lectures called «pale blue dot».

In this project, Anglada-Escude and his colleagues will be on for 90 days to track the stars using the HARPS instrument mounted on the 3.6-meter telescope in the Chilean La Silla Observatory. This device, as explained by the scientists, capable to catch the slightest jitter in the position of stars that occurs as a result of their gravitational interactions with the planets. This will help to find them, even in those cases, if the planets do not pass through the disk bodies and not cause them temporary tarnishing.

Preliminary observations of Barnard’s star, Ross 154 and Proximal Centauri has already started last Thursday, and tomorrow astronomers will proceed to complete the search for exoplanets. Monitoring, as explained by Anglada-Escude, will be open to the public, and anyone will be able to join them and try to find planets in the data that will collect HARPS.

If scientists can discover new planets, data about their properties and potential habitability may help you understand where and how to look is full of doubles of the Earth and whether planets have red dwarfs, the most numerous luminaries of the Universe, to be the main refuge is reasonable or unreasonable life.
