Scientists took pictures of two growing exoplanets, sucking matter around the newly formed star. This is the second planetary system with more than one planet ever taken.
The two exoplanets are recorded around the star PDS 70 , nearly 370 light-years from Earth. The star was only formed 6 million years ago, still "young" compared to our Sun more than 4.5 billion years old.
PDS 70 has a smaller mass than our Sun and is still absorbing matter in the universe to form the outer planets (exoplanet - the planet outside the Solar System) . Turning around the star is a large disk of dust and gas materials, according to CNN.

Two exoplanets are recorded as PDS 70 b and PDS 70 c creating gaps between the star's physical disk. This gap is estimated to have a length of 3.05-6.11 billion km.
"This is the first time we have discovered a planetary system with more than two extrasolar planets and creating a gap in its physical disk , " said Julien Girard, an expert at the Space Telescope Science Institute in Baltimore. , state of Maryland, said.
PDS 70 b is the closest planet to the central star with a distance of nearly 3.2 billion km. This distance is equivalent to the Sun to Heavenly King, the fifth planet of our Solar System. PDS 70 b was first seen in 2018, about 4-5 times more massive than Jupiter.
The recently discovered PDS 70 c is located at the edge of the physical disc, about 5.3 billion km from the central star. This distance is equivalent to the Sun to Neptune. It has a mass of 1-10 times Jupiter.
According to scientists, the planet near PDS 70 has a trajectory that is twice as fast as the other planet. The second planet is seen through the large spectral telescope of the Southern European Observatory (ESO).

The PDS 70 planetary photograph is proof that planets in the process of formation can suck a large amount of matter to create a clear gap inside the material disk around a young star.
"With astronomical systems like ALMA, Hubble or a large telescope on the ground with extremely sensitive lenses, we detect many physical disks around the stars with circles and gaps between them. If there are planets in the physical disks, is this evidence, the answer is that they exist , " Girard said.
This important astronomical discovery was published by scientists in the June 3 issue of Nature.
