Shiny exoplanet with metallic clouds challenges theory of 'hot Neptune desert'

Newly discovered exoplanet LTT9779b is the shiniest exoplanet ever found, reflecting 80% of its star's light.
LTT9779b is a 'hot Neptune' that orbits unusually close to its star every 19 hours.
The planet's high reflectivity comes from metallic clouds saturated with silicates and metals like titanium.
LTT9779b's clouds likely prevent the planet from evaporating despite scorching temperatures up to 2,000°C.
The discovery of this reflective 'hot Neptune' defies current theories about planet formation and survival.
