Speed of jets?[編輯]

The caption of the image states: "These jets lift up the relatively cool gas near the centre of the galaxy and produce shock waves in the galaxy's atmosphere because of their supersonic speed."

Is the description "supersonic speed" really even close to being accurate?

Not a big deal, but..... Tgdf (留言) 05:06, 22 April 2024 (UTC)[回覆]
