An image taken by the James Webb Telescope from Earth has revealed special structures surrounding Fomalhaut, one of the brightest stars seen from Earth.
pig Reuters, On May 8, a research team led by University of Arizona astronomer Andras Gaspar announced the discovery of three rings and an interesting void around the star Fomalhaut located near the Milky Way (the Milky Way, that is, the galaxy containing the Earth).
These are three large concentric rings that provide the most comprehensive view to date of the structure of the star system outside the solar system.

Fomalhaut is one of the brightest stars in the sky Earth and the brightest of the constellation Pisces. It is 25 light years from Earth and calculations show that its actual luminosity is 16 times that of our Sun.
Because it is very bright and one of the closest stars to Earth, the Fomalhaut debris belt was first observed in 1983.
suspended “God’s Eyes” James Webb, one of the world’s most advanced telescopes, helped reveal two additional rings closer to the star, which are obscured by starlight when viewed by other means.
According to the post above natural astronomy, These three rings may contain small planets which, early in the history of star systems, including the solar system, combined to form planets like today. They also include smaller objects such as asteroids and comets.
These three rings are intertwined and extend over a diameter of up to 23 billion km, or about 150 astronomical units (AU, equal to the Sun-Earth distance).
Although no planets have been identified around Fomalhaut, researchers suspect that the rings are created by the gravity exerted by young planets.
Our solar system also has two such rings, including the main asteroid belt located between the orbits of Mars and Jupiter, and the outer Kuiper belt. “ice giant” Star of Neptune.
The gravitational influence of giant Jupiter shrouded and shaped the main asteroid belt, while Neptune shaped the other.
Therefore, scientists believe that a large and clear gap they observe between the rings is a strong indication of a “ice giant” another in the Ƒomalhaut system.
Sao Fomalhaut is a young star 440 million years old, which is less than 1/10 the age of the Sun, so its planets are also young planets, which appeared not so long ago. But it’s the star shape “short term”, may have reached the end of half of its life cycle.
The results come from James Webb’s MIRI mid-infrared instrument, which can detect rings of matter that are hotter than the cold belts observed by other telescopes. James Webb is the most powerful space telescope built and operated by NASA today.
James Webb’s new discovery provides new insight into how a star system forms, with the first planets omitted, consistent with previous modeling studies of solar system formation, including the birth of Earth.
