#WASP-18b
"It's life, Jim..." Well, actually not! It's WAY too hot.. 🥵

But we can finally see an alien planet... 👽

JWST just created the FIRST-EVER 3D map of an alien atmosphere. It's a 2,760°C (nearly 5,000°F) inferno that literally tears water molecules apart.

This is a new era of exploration 🔭🤖🚀😁
James Webb Maps an Alien Atmosphere in 3D
Scientists used the James Webb 3D atmosphere map tool for the first time on WASP-18b. They found a 2,760°C hotspot that rips water apart. Discover the full findings.

Using NASA’s James Webb Space Telescope, astronomers have created the first 3D map of an exoplanet. WASP-18b is a gas giant 10 times more massive than Jupiter and orbits its star in 23 hours, according to a University of Birmingham press release. | Image credit: NASA/JPL-Caltech (K. Miller/IPAC)

La nostra conoscenza dei mondi al di fuori del Sistema solare procede a ritmo serrato. In appena trent’anni siamo passati dalla scoperta del primo pianeta extrasolare alla prima mappa in 3D dell’atmosfera di uno di questi mondi, il gioviano ultra-caldo Wasp-18b.
Prima mappa in 3D dell’atmosfera d’un esopianeta
Pubblicata la scorsa settimana su Nature Astronomy da un team guidato dalla Cornell University, la mappa termica del gigante gassoso Wasp-18b – un gioviano ultra-caldo a 400 anni luce da noi, rovente ...

In #NatureAstronomy präsentiert ein internationales Team die erste 3D-Temperaturkarte eines Exoplaneten. Mithilfe von Beobachtungen durch #JWST wurde bei #WASP-18b eine Atmosphäre mit unterschiedlichen Temperaturzonen enthüllt. Analysiert und interpretiert wurde diese unter der Leitung des #IWFGraz.

Line: good agreement with JWST data for WASP-77Ab, high res observations actually give more precise abundances in some instances. Also good agreement between the ERS WASP-18b spectrum and high res observations, and highly complementary. #Exoplanets5

Astronomers revisited data from JWST’s Near-Infrared Imager and Slitless Spectrograph (NIRISS) in multiple wavelengths to produce a 3D eclipse map of the "ultrahot Jupiter" exoplanet WASP-18b, 400 light years from Earth. The international team published their findings in Nature Astronomy:

JWST data show that the exoplanet WASP-18b has thermally distinct regions of its dayside. The authors mapped the sizes of these regions, measured their temperatures and potentially identify water dest...

Oldest light, seen we have, just 300 million years after the Big Bang. Flexing, JWST is. On exoplanets too: CO2 and methane on K2-18b, sulfur dioxide on WASP-39b. Telescope? More like cosmic prod debugger, hmm. #astronomy #jwst #spacetech

Астрономи створили першу 3D-мапу екзопланети завдяки телескопу Вебба
Астрономи вперше створили тривимірну карту планети за межами Сонячної системи. Це небесне тіло, відоме як WASP-18b, стало об’єктом проривного дослідження, проведеного за допомогою космічного телескопа Джеймса Вебба. Отримані результати стали величезним кроком уперед у вивченні екзопланет. Щоб дізнатись останні новини, слідкуйте за нашим каналом Google News онлайн або через застосунок.

WASP-18b is a remarkable exoplanet with an incredibly short orbital period, completing a full revolution around its star in just 1.2 days. This ultra-hot gas giant orbits its Sun-like star at a mere 0.02 astronomical units, meaning it's much closer to its star than Mercury is to our Sun. Due to t...
