<p> How is a planet at the moment of" birth "? An international team of astronomers used the telescope structure of the Southern European Observatory (ESO) to produce one of the best images ever made of a new planet in early life. In the image, the new star sailing on the disk of gas and dust created by the star to which it will orbit. </p>
<p> The new planet was dubbed PDS 70b – and the unglamorous name was given as a function of the star to which it will orbit, the PDS 70. This, in turn, is a young dwarf star: it means that it generates energy by the fusion of protons present in the nucleus of hydrogen atoms. Our Sun is also considered a dwarf star. </p>
<p> The image of the planet was captured by an ESO telescope called Sphere, whose specialty is to take pictures of exoplanets – that is, of planets outside our solar system. The Sphere telescope is part of the VLT structure, which is today the largest set of optical telescopes in the world. The VLT operates in Cerro Paranal, in the Atacama Desert (Chile). </p>
<p> The new planet, PDS 70b, is about 3 billion km away from its star – a distance equivalent to that between Uranus and our Sun. By analyzing the brightness emanating from the planet at several different wavelengths, scientists have also been able to conclude that PDS 70b is a giant gaseous type – and is sometimes larger than Jupiter, the largest planet in our solar system. The surface temperature of PDS 70b is about 1,000 degrees Fahrenheit, hotter than any planet in our Sun's orbit. </p>
<p> "These discs around the young stars are the nursery of the new planets, but so far few observations have detected evidence of the presence of new planets in them, "says researcher Miriam Keppler, who led the team responsible for the discovery of the planet in formation in the orbit of the star PDS 70. </p>
<p>" So far, however, most ' planet 'already observed could be simple noises on the disk, "she said in a bulletin released by ESO. </p>

The research around the new exoplanet is presented in two scientific articles (here and here, in English), which will be published

The dark spot at the center of the image is due to the use of a coronagraph – a kind of mask that blocks direct light from the star.

Knowing the atmosphere and the physical properties of the new planet, scientists will be able to test theoretical models that explain the formation of the new worlds. https://s2.glbimg.com/j1zGQE4qRKg2C6VqWqi3jZXpBSs=/e.glbimg.com/og/ed/f/orig (BBC)) "width =" 50 "> 19199090.web.newsletter.http://www.bbc_footer_sJkmJ5D.jpg" title = "Signature BBC footer (Photo: BBC)" width = "50"
