Re: APOD: First Horizon-Scale Image of a Black... (2019 Apr 11)
Are there any schemes depicting this black hole, its spinning axis, the disk accretion and our relative position to them? Is the black hole spinnig causing the disk accretion configuration instead of a spherical one. Thanks in advance.

Re: APOD: Fortuitous Flash Candidate for the... (2018 Apr 11)
Neufer calculates that this star is (was?) 14.523 Gigalight years away. It is 14.5 Gly distant. It was 5.8 Gly distant from our point in space when the currently observed light was produced. It took that light 9.5 Gyr to travel between the two points, because the Universe was expanding between them...

The interesting thing I noticed is that the Command Module is at a lower altitude than the Lander. I had always assumed the landing approach would be a descent only. Did the descent profile include an altitude gain, or alternatively, did the Command Module move to a lower altitude for some reason? ...

Re: APOD: Unexpected X-Rays from Perseus... (2018 Jan 02)
Maybe the explanation would be more readable in a two columns format. It's difficult for me sometimes to read it in the one column format.... There have been previous suggestions to update the APOD page code, in part for exactly this reason, to make it more readable on a greater variety of screens ...

Re: APOD: Haumea of the Outer Solar System (2017 Oct 17)
I miss in the lovely animation both earth and moon orbiting the center of masses of its binary system instead of moon just circling earth. We wouldn't be able to see it at this scale. The distance from the Earth to the Moon is about 380 000 km. The Earth-Moon barycenter is less than 5 000 km from t...

In my opinion, the vertical axis appear exaggerated, or the horizontal axis appear reduced, or the equivalent mix of both, in the same proportion as the distance between the places where the two photographs were taken to the distance between our eyes. Thanks so much Chris! Two questions: is the ver...

I apologize not being able to find in the web the complete and better resolution image version of this short-tv-film enjoyed at a public exhibition (Arstronomy at La Casa Encendida in Madrid). I found it astounding.

Re: APOD: Aurora over Icelandic Glacier (2015 Mar 10)
Thank you geckzilla for the explanation, if I understood it right there is an unintended sensor saturation effect that causes the difference with what would be expected.

Re: APOD: Aurora over Icelandic Glacier (2015 Mar 10)
Water reflected stars seem more bright than directly seen in the sky. Is it just an optical illusion based in the contrast with the foreground or image post process?

Re: APOD: The Protoplanetary Disk of HL Tauri... (2014 Nov 1
Can somebody help put a scale to this photo? The description just states it can resolve details as small as 40 light minutes. But 40 light minutes is ~720 million KM, or just shy of where Jupiter orbits. Does that mean the innermost dark band is approximately where Jupiter would orbit? Here is a pi...
