Re: APOD: Unexpected Clouds Toward the Galaxy... (2023 Jan 17)

I see more similarities with NGC 4651 than with IC 2497. https://www.nao.ac.jp/en/contents/gallery/2018/20180306-subaru-full.jpg "...The jet-like feature is strikingly coherent and narrow. This feature was previously reported by Vorontsov-Velyaminov (1959) but never interpreted as a stellar ti...

Yes. The star Ann appears to be pointing (Arrowed below) to is ~12 arcseconds south of the pulsar. The source below is Aladin. The crab pulsar labeled, and the boxes are stars from Gaia data.

Re: APOD: NGC 1365: Majestic Island Universe (2022 Dec 22)

At the core lies a supermassive black hole.

The central bar fans out into different armlike &q...

The white dot at the Helix's center... Except it isn't white. Indeed, most of the stars in the image are similarly colored to the gaseous region they are seen in (in, in front of, or behind). Which shouldn't be the case, and which makes me a bit skeptical about how the color was processed in this i...
