Groundbreaking Discovery at Our Closest Stellar Neighbor
An intriguing revelation has emerged from the depths of space! The James Webb Space Telescope (JWST) might have identified a Saturn-like gas giant orbiting Alpha Centauri A, the nearest Sun-like star to our planet.
A Stellar Leap Closer to Habitable Worlds
If confirmed, this candidate exoplanet would hold the record as the closest world discovered within the habitable zone of a star akin to our Sun. Imagine a neighboring star system harboring celestial bodies that could support life!
Advanced Technology Unveils New Possibilities
Using the Mid-Infrared Instrument (MIRI), JWST employed a coronagraph to effectively block out the star's bright light, revealing a faint signal that hints at the presence of a new planet near Alpha Centauri A.
Planet S1: What's in a Name?
Dubbed candidate S1, this potential gas giant shares a mass similar to that of Saturn and orbits at about two astronomical units from its star—twice the distance from Earth to the Sun. While it may not be capable of harboring life itself, its position in the habitable zone makes the entire system tantalizing!
The Vanishing Act: Where Did S1 Go?
Interestingly, S1 was detected in 2024 but mysteriously vanished in subsequent observations in early 2025. This disappearance could be attributed to its orbital path temporarily obscuring it from view.
