With the help of James Webb Telescope, scientists have made an important revelation about the process of planet formation. Through the telescope’s mid-infrared instrument, they studied the disk of four Sun-like stars and how steam from the ice pebbles coming inwards from the outer part makes planet formation possible.

The process of formation of planets takes millions and billions of years.

In this, the role of icy pebbles in the outer part of the disk near the planet star is played.

The ice here comes inside and turns into steam and contributes to planet formation.

The formation of planets in the universe is a very complex, long and complex process that takes millions to billions of years. It is not surprising that despite intensive observation, scientists are still trying to find out how this happened. From time to time many types of theories are given regarding this. Recently, with the help of NASA and ISA’s James Webb Space Telescope, they have succeeded in revealing this process in which the use of vaporized water plays an important role. For this, the researchers got a lot of help from the observations of the James Webb Space Telescope.

pebbles coming in from the outer disk
The researchers observed a steamy protoplanetary disk, allowing them to confirm the physical process by which solid ice-covered material flows from the outer region of the disk into the rocky planet’s region. Until now, many theories have long suggested that icy pebbles formed in the cold of the outer protoplanetary disk act as seeds in the process of planet formation. Comets are also believed to originate from here.

Vaporization Overview
The main assumption of this theory is that when icy pebbles enter the hot region, they turn into steam, which was observed by the James Webb Space Telescope and the correlation of icy pebbles of the outer disk with the steam of the inner disk was revealed. . This result has opened up possibilities of investigation on this topic through the web.

Study of the disks of four newborn stars
In this study, researchers used Webb’s Mid Infrared Instrument (MIRI) to study two compact and two expanded disks that were present around Sun-like stars. All four stars are about 20 to 30 lakh years old, which can be called newborn according to astronomical time.

Variation in amount of water or steam
Through web observations, scientists discovered whether the rocky planet’s regions with compact discs contain more water due to the arrival of more icy pebbles. They found that the compact disc contained more water than the larger disc. They found that large planets play a role as an obstacle in this process. Jupiter may have done this in our solar system

The results were initially confusing
When researchers got the data, they found the results strange. He said that for the first two months, he remained stuck in these initial results which showed that the compact discs had cold water and the larger discs had hot water. It didn’t make any sense. Because they had obtained observation data only from stars having similar temperatures.

How did the picture become clear?
But when the researchers compared the data from the compact disc with data from the larger discs, the picture became clearer and they discovered that the compact disc is very close to the snowline, where the ice turns directly into vapor, ten times the orbit of Neptune. The closer, the cooler the water is. They found that this excess water played a more important role in planet formation

To obtain this information, the researchers used MIRI’s instrument called Medium Resolution Spectrometer (MRS), which is more sensitive in capturing the vapor of the discs. Due to the results of this observation, the researchers were able to confirm the old belief that steam and dust reach the inner rocky planet areas from the outer part of the disk, which leads to the formation of planets
