☆ Titanium Clouds Engulf This Ultrahot Neptune-like Planet

Astronomers have come across the shiniest planet ever found, a mere 265 light years from our solar system. Shrouded by thick metallic clouds, this world’s temperature reaches a blistering 3,000 degrees Fahrenheit, and it quite likely rains scorching-hot drops of titanium. The find, named LTT 9779 b, was described in a paper published this month in the journal Astronomy & Astrophysics. Nearly five times as big as Earth, it’s one of the few ultrahot, gaseous exoplanets of this size that scientists have discovered. But LTT 9779 b, which sprints around its star once every 19 hours, is midsize — making it one of four or five planets in the so-called Neptune desert, and the only one with an intact atmosphere.

☆ The Milky Way's shiniest known planet has metal clouds that rain down titanium. Astronomers say it 'shouldn't exist.'

A planet five times the size of Earth was found to be the shiniest planet outside our solar system. This ultra-hot planet "shouldn't exist" as it is and could be a new class of planet altogether. This planet's hot metal atmosphere is defying astronomers' rules for how planets of this size should behave. Venus, the solar system's shiniest planet, reflects 75% of the sunlight. "We believe these metal clouds help the planet to survive" in these conditions said study author Sergio Hoyer of the Marseille Astrophysics Laboratory.

☆ Shiniest exoplanet ever found has reflective metal clouds

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. An artist's illustration shows an exoplanet, called LTT9779b, orbiting its much larger host star. The side of the exoplanet that faces its host star likely reaches 3,632 degrees Fahrenheit (2,000 degrees Celsius). And LTT9779b is so piping hot that it shouldn’t have any clouds, even those made of metal or glass.

☆ Alien planet with metallic clouds resembles 'a giant mirror in space'

Venus, the brightest object in Earth's night sky besides the moon, is our solar system's most reflective object, enrobed in toxic sulfuric acid clouds. An atmosphere with water-based clouds, as on Earth, would have been blown away by solar radiation long ago. But they believe its clouds are metallic, a combination of titanium and silicate - the stuff that makes up most of the rocks in Earth's crust. "We even think that the clouds could condense into droplets, and have titanium rain falling in parts of the atmosphere," Jenkins said. More than 5,000 planets beyond our solar system - called exoplanets - have been discovered, many with traits vastly different than our solar system's eight planets.

"This is the right's best chance for people to pick a Pinochet constitution without Pinochet's signature," said Patricio Navia a political scientist at New York University. "The political climate in Chile isn't the same as in 2019 or 2020," said political analyst Cristobal Bellolio. An estimated 3,200 Chileans were murdered and another 28,000 tortured by the state during Pinochet's rule. Many of the victims were affiliated with the socialist government of Salvador Allende, who was deposed in a 1973 coup. "The issue is that if it's more right then Pinochet's constitution, people are going to reject it," Navia added, who added the loss for Boric left the leader who once promised to bury Chile's market-led model sorely wounded.
