After offering spectacular images of different galaxies, the telescope James Webb come to detect for the first time CO₂ in the atmosphere of an exoplanet. A hot gaseous giant, unfit for life and located 700 light years away.
For the first time, carbon dioxide has been detected in the atmosphere of a planet outside the solar system. Her name is WASP-39ba gaseous and hot planet. This exoplanet is 700 light years away. The discovery excites scientists. “We have never had such clean data“, testifies Olivia Venotresearcher at the CNRS.
The data was provided by the telescope James Webb. It is the largest and most advanced telescope sent into space. It was launched only nine months ago. “We will be able to study terrestrial planets and have access to the chemical composition of their atmosphere, after detecting life, that’s another step.” reports the researcher. In recent weeks, the telescope James Webb has already sent extraordinary images of galaxy and even Jupiter. It should work for ten years.
