Scientists first saw the process of planet formation March 2, 2013

HD 100546

The possibilities are very large telescope (Very Large Telescope, VLT), which we mentioned in the article “The Best of the observatory and telescopes of the world” , this time was used for observation of the formation of the gas giant. The new planet was formed from the protoplanetary disk orbiting a young star HD 100546 (KR Flies), which is in the constellation fly a distance of about 337 light years from Earth.

From its star is a gas giant in the distance, which is approximately 70 times greater than the distance between the Sun and Earth. So far has been the subject of scientific debate, since forming planets it is not characteristic.

Положение HD 100546

Since the discovery of the first extrasolar planets that revolved around similar to the Sun Star, in 1995, scientists have identified several hundred planetary systems. This allowed scientists to create a theory of the creation of planets, but so far they have not been able to see the process of planet formation “alive”. If the data acquisition VLT telescope confirmed, the discovery would first check the validity of the theory formed.

“Until now, the theory of planet formation to reproduce can be due to the method of computer simulation. If this phenomenon is indeed the formation of the planet, then we will be able not only to study further the process of planet formation, but also their interaction with the environment at an early stage of formation, ”

– Said Sasha Quantz (Sascha Quanz) of the Higher Technical School in Zurich, Switzerland.

It should be noted that in the course of observation used a special coronagraph, which is part of the adaptive optics NACO Telescope VLT, which operates in the near infrared range.

Other scholars argue that this is not the birth of the planet, and he found a gas giant was formed earlier and are now gone from the orbit close to the star HD 100546.
