Re: Le trou noir central aime le gaz chaud !
Ah oui, c'est étonnant :
"The biggest surprise was quite how hot the molecular gas in the innermost central region of the Galaxy gets. At least some of it is around 1000ºC, much hotter than typical interstellar clouds, which are usually only a few tens of degrees above the –273ºC of absolute zero."
