He James Webb Telescope from NASA He returned to record revealing images for the history of astronomy. With the aim of studying the asteroid belt of the young Fomalhaut star –the first found outside the solar system– found two other internal rings that might account for the existence of a planetary system around her.
In the infrared imagethe American space agency discovered that around the studied star there are three nested belts that extend up to a distance of 23,000 million kilometers from it, which is equivalent to 150 times the distance from Earth to the Sun.
The first outer ring had already been clearly detected by the Hubble Space Telescope and the Herschel Space Observatory, as well as the Atacama Large Millimeter/submillimeter Array (ALMA). However, Webb has now revealed the existence of two other interiors, never before seen.
“These dust structures are much more complex than the asteroid and Kuiper dust belts in our solar system,” explained NASA, from where they stated that They did not expect to find this find.
“We have learned a lot regarding how outer disks form and evolve,” he said. Schuyler Wolffmember of the team at the University of Arizona in Tucson.
What are these discs or belts?
Gaspar Andrásfrom the same research institution, described Fomalhaut as “the archetype of rubble discs found in other parts of our galaxy, because it has components similar to those found in our own planetary system.
Along with images of the disks gravitating around the young star, NASA explained that these belts are “most likely” “forged by gravitational forces produced by unseen planets”.
In that sense, George Riekeanother member of the team and US chief scientist for the Mid-Infrared Instrument (MIRI), said: “The belts around Fomalhaut are a bit of a mystery novel: where are the planets?”
In turn, the researcher added: “I think it would not be too hasty to say that there is probably a really interesting planetary system around the star”.
