Re: APOD: Halo of the Cat's Eye (2020 Jun 07)

If radius is proportional to time back, it looks like at first there was no rotation (outer third), then equal emission in all directions (middle third), and now leisurely rotation (inner third). Is this a correct interpretation? If so, what caused the change in rotation, perhaps asymmetric emission?

Is this in real-time? I mean, did these two black holes really merge in about a second?? Wow!

Re: APOD: Venus at the Edge (2012 Jun 09)

On my screen, the circle of Venus measures 108 mm high and 109 mm wide. Is the planet orb really that much flattened, or is it just an artifact of the image and/or rendering?
