A team of astronomers got the first confirmed image of a planet orbiting the dwarf star PDS 70 . The photograph reveals how this world is blazing through the gas and dust that surrounds the star. The results were obtained thanks to the instrument SPHERE located at Very Large Telescope (VLT) – the world's most advanced visible light observatory – [19659003] The newly formed planet is the bright spot observed to the right of the blackened center of the snapshot
The planet, which is named PDS 70b is the bright spot located to the right of the center blackened from the snapshot, according to published today in a first article and second work published in the journal Astronomy and Astrophysics . The black dot is due to the use of a device called coronagraph, which allows to block the light of the star and thus to observe objects dimly lit.
"These discs around young stars are the places where the planets were born, but so far only a handful of observations have detected traces of planetary babies in them" , explains the scientist Miriam Keppler of the Max Planck Institute of Astronomy, in a statement from European Southern Observatory (ESO, for its acronym in English). The young planet is 3 billion kilometers from its star, a distance similar to that separating our Sun from Uranus the seventh planet of the solar system.
[19659004] Astronomers also analyzed the brightness of the PDS 70b at different wavelengths which allowed them to deduce some remarkable features such as the properties of their atmosphere. According to his research, the atmosphere of the planet in formation is cloudy. In addition, scientists believe that PDS 70b is a gaseous giant superior to Jupiter the largest planet in the solar system. The surface of this young world could count on a temperature of about 1000ºC .
The findings, according to the scientist André Müller – of the Max Planck Institute, "offer a new perspective on the early stages of planetary evolution that are complex and that we do not quite understand. "Since 2014, the SPHERE instrument – located in the Chilean Paranal Observatory – has allowed us to study giant worlds revolving around nearby stars of the solar system's borders Unlike other techniques of looking for exoplanets SPHERE realizes direct images by blocking the light of stars Recently, the use of this camera has helped to portray the discs that form around the young stars, which gives us new clues as to how the planets are created and on the own history of the solar system .
