Astronomers have observed a planet outside our solar system, orbiting the Alpha Centauri system, the closest star system to Earth, raising intriguing possibilities about the potential for life.
According to gazeta.ru, Russian astronomer Yfgini Burmestrov from Bayram Technical University announced the discovery of this exoplanet, nicknamed “ghost,” which was initially detected in 2024.
The James Webb Telescope, utilizing its infrared instrument MIRI, played a crucial role in detecting the faint thermal radiation emitted by the planet. However, its proximity to the shining stars Alpha Kanouris A and B made observations exceptionally challenging, as the planet’s signal was reportedly ten thousand times weaker than the light from the stars themselves.
“It took to make sure that this is an external planet and not a passing asteroid for a long time. Modern devices have helped to reduce the brightness of the radiation of the mother stars and monitor a very weak signal. According to the accounts, the planet is about two astronomical units of alpha Kanqouris A.”
Scientists have determined that the exoplanet is a gas giant, with a mass between 90 and 150 times that of Earth, and slightly larger than jupiter. Its atmosphere is primarily composed of hydrogen and helium, and it lacks a solid surface.
“He thought for a long time, the planets are very rarely formed in bilateral systems due to gravitational disorders. But this discovery turned our concepts about the formation of planets upside down. It turned out that the stable worlds can arise even in such turbulent conditions.”
The planet has been dubbed the “ghost” planet as subsequent attempts to observe it this year have been unsuccessful,leading to speculation about its disappearance.Theories range from a catastrophic collision and ejection from the system to a “lighting” effect caused by the star’s radiation.
“Most likely, it makes the bright light of a star adjacent to the planet is not visible to telescopes. But it is expected to become visible again in 2026 and 2027.”

Frequently Asked Questions
What is Alpha Centauri?
Alpha Centauri is a triple star system,the closest to our solar system.It consists of two sun-like stars, Alpha Centauri A and Alpha Centauri B, and a red dwarf star, proxima Centauri.
What is MIRI?
MIRI stands for Mid-Infrared Instrument, an instrument on the James Webb Space Telescope that is designed to detect infrared light. This allows it to see through dust clouds and observe faint objects, such as exoplanets.
Why is it called the “ghost” planet?
The planet is called the “ghost” planet because after its initial detection, subsequent attempts to observe it were unsuccessful, leading to speculation about its disappearance.
