Astronomers are investigating whether or not Proxima Centauri, the star nearest our photo voltaic system, could host a whole system of planets after they found it was surrounded by belts of mud.
The discover suggests our nearest stellar neighbour may harbour a cloud of orbiting asteroids and doubtlessly planets.
One Earth-like planet was found orbiting the purple dwarf final 12 months. Dubbed Proxima b, it resides in its star’s liveable zone and is roughly the scale of our personal world.
Enrique Macías was one in all a workforce of astronomers who used Chile’s Atacama Large Millimeter Array (Alma) telescope to detect the particles.
He instructed The Verge: “So we expect that at any time when there’s a planet round a star, there’s going to be some type of asteroid belt as effectively.
“It’s just debris from the formation of the system. That’s what we were looking for.”
There could also be as much as three mud areas, he added. He stated he was badured of discovering additional planets.
The whole mbad of Proxima Centauri’s recognized mud belt is a small fraction of Earth’s and could be very chilly, at –230C.

Dr Guillem Anglada-Escude led the 30-strong workforce that found Proxima b in 2016.
The Queen Mary, University of London tutorial stated: “We hope these findings inspire future generations to keep looking beyond the stars. The search for life on Proxima b comes next.”
As the closest star exterior our photo voltaic system, about four.25 gentle years away, Proxima Centauri has been mentioned as a possible vacation spot for Earth’s first interstellar probes.
One contender consists of Breakthrough Starshot, a venture to create a light-sail spacecraft that might carry out a flyby of the planet on its technique to doc the broader Alpha Centauri system.
