US EditionAstronomers solve mystery of how a mirror-like planet formed so close to its star
- Scientists have discovered a scorching exoplanet called LTT9779b, which is the brightest planet found outside our solar system. It has temperatures of up to 2,000 degrees Celsius and unique cloud formations made of titanium and silicate that reflect 80% of incoming light.
- LTT9779b is a planet that defies expectations as it shouldn't exist due to its proximity to its star. The high reflectivity of its clouds and the heaviness of its metallic atmosphere allow it to survive close to its star without its outer layer being burned away.

WASHINGTON : It is a planet astronomers say probably should not even exist.Researchers said on Monday they have spotted a truly extreme planet beyond our solar system, a blazingly hot world a bit bigger than Neptune that orbits a sun-like star every 19 hours and appears to be wrapped in metallic clouds ma
Shiniest exoplanet ever found has reflective metal clouds - WSVN 7News | Miami News, Weather, Sports
(CNN) — An ultrahot exoplanet that zips around its host star every 19 hours is the shiniest exoplanet ever discovered. The scorching world, dubbed planet LTT9779b, has reflective metallic clouds made of silicates and metals like titanium. The exoplanet is the largest “mirror” in the universe that astronomers have spotted to date. The planet is located 262 light-years from Earth. Initially spotted by NASA’s planet-hunting TESS mission in 2020 and…
