Re: APOD: Earthset from Orion (2022 Nov 23)
Why does the moon look so featureless and kind of dark? Since we see the planet Earth way behind the Moon and since the Moon always presents the same face to the Earth because of tidal locking, what you are seeing is the "dark side of the Moon". It is actually more featureless because the...

Hi,
I did a similar processing of the Mystic Mountain HST dataset, which also clearly shows evaporating gases around its contour.

Re: APOD: The Tarantula Zone (2020 Nov 13)
The statement that this " view spans about 2 degrees or 4 full moons " seems rather fishy to me. :fish: The precise FOV is 1d 3' 47.8" x 1d 18' 46.0". Ignacio So, this is roughly 1 degree x 1 degree, and not 2 degrees wide per the text? How did you determine the exact field of v...

Re: APOD: The Tarantula Zone (2020 Nov 13)
I registered both images against each other, and cropped the SN area with the same geometry. Could it be the red star at the center, sided by two white stars?

Re: APOD: M16 Close Up (2019 Aug 10)
Hi, Being the author of today's image, let me chip in. I love true color astro images, even more so (in general) than false color ones. That being said, one can make a strong case for Hubble palette images. From a purely technical point of few, these images tend to reveal more subtle and fine struct...

Re: APOD: Galaxy Cluster Abell 1689 Deflects Light (2013 Sep
Are black holes of dark matter possible in theory? If yes, Is there any observational evidence of their existence? It isn't obvious what sort of matter we have once it is "inside" a black hole. Similarly, we don't really think of a black hole as being made out of any particular sort of ma...

I was late to the main event, but still able to capture in a hurry the beauty of the moment with this single shot taken with a simple grab-and-go camera and a small tripod, through hazy clouds.

Re: APOD: M8: The Lagoon Nebula (2013 Aug 17)
This is a very beautiful picture of a much-photographed object. I checked out the imaging data of the picture and was a bit confused. As far as I could understand, today's APOD is not an RGB image, photographed through red, green and blue filters. It is also not an image which has been enhanced wit...

Re: APOD: Planck Maps the Microwave Background (2013 Mar 25)
Thanks for the explanation. So, to be clear, one should think this as matter (dark and regular) measured in its energy equivalence via mc^2 and then compared with dark energy? In that case, the importance of dark energy strikes me as even more impressive, given the huge conversion factor involved. I...

Re: APOD: Planck Maps the Microwave Background (2013 Mar 25)
Basic question: When referring to percentages of dark matter, dark energy and "regular" matter, in terms of what is that proportion exactly? Is it in terms of energy, as in E=mc2 for "regular" matter? Or is it in terms of how dark terms weight versus "regular" matter gr...
