Astronomers of the Institute The planetary PDS 70b walks a disc of matter surrounding the young star PDS 70 in the constellation of diodes Centaur electroluminescent 370. The planet PDS 70b is the first in the history of the planet photographed at the training stage, which is pioneering through the protoplanetary disk.

Earth years.

Dark spot in the center of the image – this is an "artificial moon", a mask that astronomers use to block the radiation of stars and see objects nearby. The black dot behind the PDS 70 star, which erupted 10 million years ago, is a protoplanetary disk Scientists have estimated the distance from the star to the planet at three billion kilometers – approximately from the Sun to Uranus

Despite the great distance to the star, the temperature, the planet PDS 70b is formed in the photo. on the surface of the planet are you much – about 1000 ° C; it's more than any of the planets in the solar system. PDS 70b is a gaseous giant with a mass of several masses of Jupiter

An analysis of the radiation of a "newborn" planet made it possible to draw conclusions about its atmosphere, say astronomers: it is quite dense and filled with drops of fluid or dust. observe the planets in formation; named a number of candidate stars, in the discs around which have found close aggregates of matter, but only on PDS 70b astronomers confidently speak of a planet in the early stages of training; other candidates deserve to be studied and may constitute minor anomalies in the distribution of the disc

Confirmation of the existence of the "newborn" planet and photograph of its scientists thanks to the SPHERE instrument. A very large telescope of the Southern European Observatory of Chile. 19659003] The SPHERE tool blocks the bright light of stars, its algorithms and optics are optimized to capture low light, filter noise and give maximum countermeasure. The picture of what is happening in the immediate vicinity of the stars.

When SPHERE is in surveillance mode, he photographs the star for several hours, then his algorithms reject a signal that has a fixed source (star radiation) and retains a signal source

results of the observations are published in two articles (1, 2) in the journal Astronomy & Astrophysics
