It is a moment of birth that until now has remained inconceivable, but astronomers now say that they have the first confirmed image of the formation of a planet
The awesome snapshot shows a glowing mbad – the budding planet – traveling through the dust and gas surrounding a young star, known as the PDS70, which would be 370 light-years from Earth
. Black circle in the center of the image, to the left of the planet, is a filter blocking star light, allowing the appearance of other features of the particular system
The planet recorded by his instrument Sphere Very large telescope of Europe From the Southern Observatory, is a gaseous giant with a mbad greater than that of Zeus.
The planet recorded by the Sphere of the Very Large Telescope of the European Southern Observatory is a gaseous giant of a mbad greater than that of Jupiter. Indeed, it is so far from its star as the planet Uranus from our own sun. Other badyzes have shown that it has a turbid atmosphere and a surface temperature close to 1000 ° C

"These discs around the young stars are birth planets, but until now only a few observers have identified "baby-planets" inside, said Miriam Kepler of the Max Planck Institute of Astronomy in Germany, responsible for the research published in the journal Astronomy and Astrophysics.However, d & # 39, other ground observations have not provided conclusive evidence.
"The problem is that up to now, most of these candidate planets could be a feature of the planet." 39 "album," she added. "The advantage of our own detection is that we have identified [τον νέο πλανήτη] with many different observation instruments, different filter belts and different years."
Young planets have also have been detected in the past thanks to the Kepler telescope. But Kepler said that this method also has limitations, since it relies on reducing light from the star as the body moves between it and the telescope.
"The most peculiar feature of this new planet is that we can describe it directly because Kepler, for example, is derived from indirect techniques," she said. "In this case, we now have a direct image [του πλανήτη] in his" birthplace ", which is the district's disk.This is particularly important because people have long wondered how these planets are formed and how dust and the material of this disc are formed on a planet, and we can now see it directly. "
Kepler also said that the star around which turns the newborn planet only has five at six million years ago, noting that this planet could still be
Astronomers, she says, now have a great mission ahead of them. Explore through observations how the planet is developing, as well as trace its orbit around the star, a journey that is expected to last about 120 years.
Dr. Zoe Leinhardt, an astrophysicist specializing in planetary formations at the University of Bristol and who did not participate in the research, hailed the discovery
"This is a relatively new star that shows all the clues, accompany the appearance of a planet, and indeed there is one there.For astronomers, most of the time, it is very rare that we can show a We just have to interpret it, "she said Leinhardt added:" It's almost indisputable, so it's very exciting. This confirms that our theory of planet formation is correct. "
Dr. Leinhardt also appreciated that it is possible that the planet has neighbors or that other planets may appear over time." The way planets form, a great deal Planet with the mbad of Zeus would be easier to find … and also these great planets would form faster, "he said." This discovery shows that the formation of planets is underway in this system. "[19659011] Dr. Dimitris Stamatelos, head of the research group on the theoretical formations of stars and exoplanets at the University of Central Lancaster, could not hide his enthusiasm.
"This is a spectacular discovery, because it is probably the first direct and sharp observation of a planet while it is formed in a new protoplanetary disk", he said, adding that if the discovery confirmed some theoretical predictions, also created an enigma. "There is still a mystery about how such a large planet can be formed at this unusually long distance from its parent star," he said. "The theory of established planet-building has difficulty in explaining the existence of this planet."
