James Webb Telescope Finds Atmosphere on Exoplanet TOI-561 b
詹姆斯·韋伯太空望遠鏡在系外行星 TOI-561 b 上發現大氣層
The James Webb Space Telescope (JWST) has made a groundbreaking discovery: the exoplanet TOI-561 b possesses a thick atmosphere, defying traditional scientific models.
詹姆斯·韋伯太空望遠鏡有了開創性的發現：系外行星TOI-561 b擁有濃厚的大氣層，這顛覆了傳統的科學模型。
Usually, a "super-Earth" this close to its star would lose its gaseous envelope due to intense radiation.
通常，如此靠近恆星的「超級地球」會因強烈的輻射而失去其氣體外殼。
However, TOI-561 b, which orbits its star in under 11 hours, retains a volatile-rich blanket.
然而，這顆繞行其恆星週期不到11小時的TOI-561 b，卻保留了一層富含揮發性物質的保護層。
While a bare, rocky planet should reach 2,700°C, TOI-561 b remains at a cooler 1,800°C.
雖然一顆裸露的岩石行星理論上應該達到2,700°C，但TOI-561 b的溫度卻維持在較涼爽的1,800°C。
Experts describe the world as a "wet lava ball" with a global magma ocean covered by gases like water vapor and carbon dioxide.
專家將這個世界描述為一顆「濕潤岩漿球」，擁有被水蒸氣和二氧化碳等氣體覆蓋的全球岩漿海洋。
It provides a vital template for astronomers searching for atmospheric signatures on other planets across the galaxy.
它為天文學家在銀河系中尋找其他行星的大氣特徵提供了重要的範本。
