Have you ever heard about Ariel space telescope? This is the space mission that is aimed at surveying planets found beyond our solar system, otherwise known as exoplanets or extrasolar planets, in order to study the formation and evolution of their atmospheres. Do you have any details about this mission or what do you think about that mission at all?

No, I hadn't heard about it.

But Wikipedia has heard about it: https://en.wikipedia.org/wiki/ARIEL
