Re: APOD: Animation: Black Hole Destroys Star (2024 Jun 16)

It probably makes more sense to visualize that scenario the other way around... a black hole falling straight into the star. And why is that? When I think of this event I picture the likely less massive object - the star - doing the falling into the likely larger object - the black hole. The black ...

Re: APOD: Messier 66 Close Up (2024 Jun 13)

We can't see any major star formation in NGC 3628 (if it has any) because of its edge-on perspective, but it appears that M66 is the Leo Triplet member that has the highest rate of star formation. (M65 appears to have almost none.) An interesting ESO image shows the cold gas in M66, which provides ...

Re: APOD: Animation: Black Hole Destroys Star (2024 Jun 16)

It's quite rare, but it would be fun to see a simulation of a star falling straight into a black hole, a direct hit as it were. Well - scenarios 1-4 are possible paths to scenario 5. Mouth open - star in - mouth shut ;-) "When a star flies directly into a black hole, dramatic and fascinating p...
