Scientists were able to photograph the “newborn” planet.
Scientists-astronomers working with the telescope Very Large Telescope of the European southern Observatory, made the first confirmed picture of a planet, which is at the stage of its formation. “Newborn” planet, dubbed PDS 70b, seen in the picture, as a bright spot in the cloud of gas and dust surrounding a young star, informs Rus.Media.
PDS 70b planet revolves around the star PDS 70 is about the same distance as Uranus relative to the Sun. Spectral analysis of light allowed the scientists to figure out what PDS 70b planet is a gas giant, several times more massive than Jupiter. The temperature of the lower atmosphere and the surface of this planet is about a thousand degrees Celsius. The observation of the planet PDS 70b was carried out using the tool Spectro-Polarimetric High-contrast Exoplanet REsearch (SPHERE) of the VLT telescope, which was designed and created with the purpose of “hunting” for young exoplanets.
Its main function is to block the bright light of the Central star with an instrument-coronagraph and the strengthening of the dimmer light from the planet to obtain a sufficient contrast level of the picture. Star PDS 70 is located at a distance of 370 light years from Earth, and she is very young, its age does not exceed 10 million years. Due to the presence of “gaps” in the protoplanetary disk, researchers have long suspected the existence of planets around this star. And now, thanks to the capabilities of the instrument SPHERE, researchers saw these gaps clearly enough. Monitoring system of the star PDS 70 was conducted in two review programs, SHINE and DISK, both programs were used for the instrument SPHERE, which allows us to study the system of young stars. In the framework of the SHINE was studied 600 nearby young stars, and in the framework of the program DISK, more attention was paid to the study of protoplanetary disks and the processes of forming new planets.
