☆ The Milky Way's shiniest known planet has metal clouds that rain down titanium. Astronomers say it 'shouldn't exist.'
  + stars: | 2023-07-12 | by ( Marianne Guenot | ) www.businessinsider.com   time to read: +3 min
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.

☆ Alien planet with metallic clouds resembles 'a giant mirror in space'
  + stars: | 2023-07-10 | by ( Will Dunham | ) www.reuters.com   time to read: +4 min
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.

☆ Shiniest exoplanet ever found has reflective metal clouds
  + stars: | 2023-07-10 | by ( Ashley Strickland | ) edition.cnn.com   time to read: +4 min
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.

☆ WTO chief rebukes countries over stalled fishing negotiations
  + stars: | 2022-12-20 | by ( Emma Farge | ) www.reuters.com   time to read: +2 min
GENEVA, Dec 20 (Reuters) - The head of the World Trade Organization chided countries for failing to make headway on negotiations covering fishing and agriculture because of infighting over who should lead them. Delegates told Reuters that a proposal was floated for Turkey and Norway's ambassadors to lead the agricultural and fisheries negotiations but these choices were rejected by India, delegates said. "Six months of not negotiating is not acceptable," WTO Director-General Ngozi Okonjo-Iweala told countries in a closed-door meeting of its General Council, according to remarks relayed by the body's spokesperson late on Monday. "While WTO members are not doing the job, fish stocks continue to decline at an alarming rate," said Remi Parmentier, director of the Varda Group, a think-tank focused on biodiversity. WTO spokesperson Dan Pruzin told journalists it was "never easy" to choose chairs of negotiations but said this case was proving "particularly difficult", without elaborating.
