APOD: A Kilometer High Cliff on Comet -... (2024 Dec 16)
2024年12月16日 · The APoD is a truly incredible work of science and engineering. The many, many teams of people who contributed to this sort of thing should be justifiably deeply proud of their achievements. Still, I would like to stand on this world before Sol sublimates it away into a series of meteor showers.
APOD: M51: Tidal Streams and H-alpha Cliffs (2024 Dec 13)
2024年12月13日 · Yes, but the APOD reveals a long jet from this galaxy! It is probably the black hole here acting up. My favorite background galaxy behind the M51 system is barely visible in the APOD, because revealing it would have required another way of observing and processing this system. It is a background galaxy called IC 4278.

APOD: Messier 2 (2024 Dec 19) - Starship Asterisk*
2024年12月19日 · The section shown in the APOD is the center of the globular cluster. There is therefore a very good chance that you will see one thing in a backyard telescope: white! The range visible to the humaneye is 380-780 nm. In the APOD image, 275 nm was assigned to RGB blue, 336 nm to RGB green and 438 nm to RGB red.

APOD: Cosmic Latte: The Average Color of... (2024 Dec 01)
2009年12月4日 · Maybe a little 'late' for the discussion, but as a Brazilian I would like to suggest another possible name: ‘Flicts’ - that is the name of a color presented in the children’s book that goes by the same name, written by the Brazilian author Ziraldo.

APOD: NGC 206 and the Star Clouds of Andromeda (2024 Nov 28)
2009年12月4日 · APOD 28 November 2024 annotated.png At far left, there is a huge, broad, vaguely L- or V-shaped, bluish "star cloud" - but this isn't NGC 206, but something much larger. However, while the overall color is bluish, there are relatively few individual bright stars in it.
APOD: NGC 7635: The Bubble Nebula (2024 Oct 30)
2024年10月30日 · When the nice folks at APOD reached out to me last week about this image being selected, I offered up a newer SHO version of the Bubble Nebula I took in 2021 to replace it - but they opted to keep the older version. I respect their decision, as it is ultimately their website and their subjective eyes as to what deserves to be an APOD.
