I think they ment RADIO-active. It is a high energy radio source. Very noisy.

There is a lot going on in there hidden by that gas cloud.

[Hebrews 11:6]

Makes sense. Thanks.

“I think they ment RADIO-active. It is a high energy radio source. Very noisy.”

It’s not only active in radio, but in high-energy radiation like X-rays and gamma rays. Often active galaxies exhibit two large jets of material originating from the central black hole.

“There is a lot going on in there hidden by that gas cloud.”

That’s for certain! Every so often an entire star system gets sucked in to the black hole...
