The Ultra-Reflective Titanium Clouds of Hot Neptune Planet LTT 9779 b
Discovered by the Transiting Exoplanet Survey Satellite (TESS) and subsequently analyzed in exquisite detail by the European Space Agency’s CHEOPS mission , the exoplanet LTT 9779 b represents one of the most extreme and baffling physical environments ever confirmed by astronomers. Located approximately 260 light-years from Earth in the southern constellation of Sculptor, this extraordinary body orbits its host star, a metal-rich yellow dwarf , at a distance of just 2.5 million kilometers. This proximity is roughly 1/60th of the distance between Mercury and our Sun, exposing the world to a relentless barrage of high-energy stellar radiation. Under normal circumstances, a world of this size would have its atmosphere completely stripped away, yet this unique body has managed to retain its volatile envelope against all physical expectations. The Phenomenon of the Cosmic Mirr...
