Astronomers recorded the birth of a planet around the dwarf star PDS 70, the first time that an image of a planetary formation was captured.
This important step, made by experts from the Max Planck Institute of Astronomy in Heidelberg, Germany, was made possible by the SPHERE instrument of the very large telescope of the European Southern Observatory (ESO) located in the desert of Atacama, Chile.
This body, baptized PDS 70b is located about three billion kilometers from the central star, a distance similar to that between Uranus and the Sun.
According to the research, it has a temperature of about 1000º C, which makes it much hotter than any planet in our solar system.
Experts suggest that it is in orbit PDS 70 to 22 times the distance between the Earth and the Sun. It completes an orbit around the star in 118 Earth years.
PDS 70b can be seen in the following image on the right side of the black dot in the center of the cloud of dust and gas.
"These discs around the young stars are the places where the planets were born, but up to here only a handful of observations have detected traces of planetary babies in them ", he said Miriam Keppler who leads the team behind the discovery of the planet PDS 70, still in training.
"The problem is that, until now, most of these candidate planets could be mere phenomena on the disc," he added.
The discovery of the young partner PDS 70 has been cataloged as "Exciting Scientific Result" which has already deserved further investigation. "In recent months, a second team, involving many astronomers from the discovery team, including Keppler, has continued to study the first observations to further investigate the new planetary partner PDS 70", he said. Explain. ESO through a statement.
"Not only did they get the spectacular image of the planet shown here, but they were even able to get a spectrum of the planet. The badysis of this spectrum indicates that his atmosphere is cloudy " he added
In the following video, shared by the ESO, you can see a detailed zoom on the accurate picture of the birth of the planet.
It should be noted that SPHERE studies exoplanets and disks around nearby stars using a technique known as high-contrast imaging .
"Even by blocking the light of a star with a coronagraph, SPHERE must apply cleverly designed observation strategies and data processing techniques to filter the signal of weak planetary partners around young stars brilliant in several wave lengths and at different times, "they say of ESO.
