James Webb Space Telescope forecasts clouds of melted rock on this blisteringly hot exoplanet

"WASP-43b is a reminder of the vast range of climates that are possible on exoplanets and the many ways in which Earth is special."

The James Webb Space Telescope (JWST) has performed a weather report for a distant planet. The powerful space telescope forecasts extreme wind speeds, blisteringly hot temperatures and blankets of rock clouds for the world, named Wasp-43b. As such, the extrasolar planet, or "exoplanet," demonstrates just how strange alien planets outside the solar system can be. WASP-43b orbits a star located around 283 light-years from Earth; it sits so close to its star, in fact, that it completes an orbit in just around 19 Earth hours. This proximity, equal to around just 1.3 million miles (2.1 million kilometers), means the planet, with a mass around 1.8 times that of Jupiter and a width 0.9 times that of the gas giant, is tidally locked to its star, WASP-43.

Temperatures on Exoplanet WASP-43b

A mere 280 light-years from Earth, tidally locked, Jupiter-sized exoplanet WASP-43b orbits its parent star once every 0.8 Earth days. That puts it about 2 million kilometers (less than 1/25th the orbital distance of Mercury) from a small, cool sun. Still, on a dayside always facing its parent star, temperatures approach a torrid 2,500 degrees F as measured at infrared wavelengths by the…

SRON-astronomen hebben de aanwezigheid van aluminiumoxide (AlO) gevonden in het spectrum van exoplaneet WASP-43b. Dit komt als een verrassing omdat verwacht wordt dat AlO verscholen zit in de lagere atmosferische lagen. Het is pas de tweede keer dat astronomen het molecuul in de atmosfeer van een exoplaneet waarnemen.

Best Alien Planet Weather Map Ever Reveals a Scorching World

A super-hot planet 260 light-years from Earth is showing signs of water vapor in its atmosphere, despite scorching temperatures that are hot enough to melt steel, according to the best weather map ever created of an alien world.

The Jupiter-size alien planet, called WASP-43b, is so hot that daytime temperatures reach 3,000 degrees Fahrenheit (1,648 degrees Celsius). At night, it's a bit cooler — about 1,000 F (537 C) — still hot enough to melt silver.

ECCO LA MAPPA PIÙ PRECISA DELL’ATMOSFERA DI UN PIANETA “ALIENO”: È CALDISSIMO E SENZA NUVOLE

ECCO LA MAPPA PIÙ PRECISA DELL’ATMOSFERA DI UN PIANETA “ALIENO”: È CALDISSIMO E SENZA NUVOLE

Arriva la mappa piu’ precisa dell’atmosfera di un pianeta esterno al Sistema Solare. L’ha ottenuta, e pubblicata sulla rivista Science, il gruppo di ricerca coordinato da Kevin B. Stevenson, del dipartimento di Astronomia e Astrofisica dell’universita’ di Chicago. Ottenere una mappa cosi’ completa e’ stato possibile perche’ i ricercatori hanno potuto osservare ben tre anni di storia del pianeta,…
