A giant planet may orbit our closest sunlike neighbor

SMRTR summary

A possible giant planet has been discovered orbiting Alpha Centauri A, our closest sunlike neighbor star, using the Webb telescope. Located within the star's habitable zone about twice Earth's distance from the sun, the candidate planet appears similar in size to Jupiter with a mass like Saturn, potentially making it a gas giant unsuitable for life. Scientists plan follow-up observations in 2026 to confirm this significant finding.
