They capture the birth of a planet

Astronomers recorded the birth of a planet around the dwarf star PDS 70, it is the first time that an image of a planetary formation is captured.

This important discovery was made by experts from the Max Planck Institute of Astronomy in Heidelberg, Germany, thanks to the SPHERE instrument of the Very Large Telescope of the European Observatory Austral (ESO), located in the Atacama Desert, Chile, as revised by the portal biobiochile.cl

After investigations has a temperature of about 1000º C, which makes it hotter than any planet in our solar system, called PDS 70b, is located about three billion kilometers from the central star, a distance similar to the Existing between Uranus and the sun.

Experts suggest that it is in orbit PDS 70 to 22 times the distance between the Earth and the Sun. Complete an orbit around the Sun. The star in 118 Earth years, further can be seen in the following picture on the right side of the black dot in the center of the cloud of dust and gas.

Miriam Keppler, leader of the Planet PDS 70 discovery team, said that "these discs around the young stars are the birthplaces of the planets, but so far only a few observations have detected signs of planets. "

" The problem is that, until now, most of these candidate planets could only be phenomena on record. "

The discovery has been cataloged as an "exciting scientific result" in which further investigation is already underway.

"In recent months, a second team, involving many astronomers from the discovery team, including Keppler, has continued to study initial observations to investigate the new companion we. or Planetarium of PDS 70 in more detail, "the ESO explained in a statement.

" No 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 analysis of this spectrum indicated that its atmosphere is cloudy. "

" Even by blocking the light of a star. As a coronerograph, SPHERE needs to apply intelligent observing strategies and data processing techniques to filter the signal of weak planetary partners around bright young stars at multiple wavelengths and at different times. "He says. .
