Beijing time, July 11, according to foreign media reports, astronomers have photographed the "baby planet" for the first time, which is in the process of forming a disk of gas and dust surrounding the stars. The image is the birth of the planet depicted by artists. They speculate that the planets formed in a series of collisions
The latest observations and "baby planets" are located to the right of the star in the picture. The latest discovered baby planet is called PDS 70b. Its volume is several times that of Jupiter . There may be a cloudy atmosphere. Scientists believe that this planet only forms 5-6 million years. For a long time, researchers have been committed to searching for baby planets, which is the first time that the existence of baby planets has been confirmed. The young dwarf star PDS 70 is less than 10 million years old, and its planet is believed to have formed only 5-6 million years.
The latest baby planet discovered is called PDS 70b, which is several times the size of Jupiter and may have a cloudy atmosphere. A team led by the Max Planck Institute for Astronomy in Germany discovered that the planet's orbit is similar to the planetary orbit from the sun at Uranus .
Infant planets orbit around stars for about 118 years, and their surface temperature is considered to be above 1000 degrees Celsius, much higher than the surface temperature of any planet in the solar system.
The light of the young dwarf star PDS 70 is blocked by a tool called the "coronameter", which makes it easier for astronomers to observe more dim planets.
How did the planets be born? The widely accepted theory among scientists is that the residual matter of planets born when the star of forms . The main components of planets are gas and dust. Planets orbit around stars in a larger disc-like orbit. Over time, the residual material of the star collides and gradually accumulates. As the volume becomes larger, the planet's gravity gradually increases, and the accumulation attracts more wreckage material. This process may nurture other planets.
Once a celestial body forms a clear orbital path around the main star, it forms a planet. Currently, researchers have only observed in the solar system that they have discovered that planets are nurtured through this theoretical model, so observing the early stages of the PDS 70b planet will help astronomers better understand the birth process of the planet.
