I thought that meant Henize. Thanks geckzilla.

I should note in the original data there were these little black things I had to clean off. As for why these artifacts are in the WFC3/IR data, I don't know.

Oops. I meant Flying Lizard, not Flying Bat. Flying Bat is the popular name of Sh2-129. Back on the topic.

So the Magellanic Clouds do not belong to the Milky Way then. Interesting. Also, it seems you guys overlooked an irregular galaxy which could be the LMC's twin. Behold NGC 4449: https://upload.wikimedia.org/wikipedia/commons/thumb/c/c1/Starburst_in_NGC_4449_%28captured_by_the_Hubble_Space_Telescope%...

So, what would have happened 2 million years ago (+light travel time) to create this wonder? A huge compression, shock, or swirling of proto-stellar material? From what I know, many small dwarf galaxies have their gas saved for later as they are small and dwarfed by the giant spiral galaxies like t...

Thanks geck. I was quite close to mailing STScI. The quasar is QSO J1244+1721, located 9 billion light years away in the constellation Coma Berenices.

Of an anonymous quasar next to a star, and some other galaxies. I can't find any information on what is the ID of this quasar: does anyone know?

The American Astronomical Society met in Toronto, Canada, in August 1959, when I was 19 and already an astronomer. At the meeting, Ambartsumian suggested the presence of a blackhole at the center of our Galaxy, and I thought that was the stupidest idea I'd ever heard in my life! And indeed it does:...

Thanks Ann for your write-up. Nice to know there are reasons why planetary nebula N66 is 6 light years across and is still bright and huge, larger than in the Milky Way. Yes, the Milky Way and Andromeda have little gas left for star formation and are considered "dead", doomed to become a l...

I'm wondering why the LMC's emission nebulae easily grow to over 100 light years in diameter, and complexes like the Tarantula Nebula and N11 are over 1000 light years across! I've seen regions like this in other more normal galaxies like M33 and C57, so why do HII regions form larger and easier in ...

Good luck figuring it out. I'm still boggling over the Red Rectangle. Yes, this paper made me understand what happened to the star a lot better. It was an ordinary post-AGB protoplanetary and then suddenly, around 1980, bam! It's emission lines transformed to a planetary nebula suddenly. This gave ...

I have a weird obsession with this PN for some reason. To fuel that, here's a recent paper from ArXiv on it. You may find this interesting.

Sorry if this is completely unrelated, but I think SIMBAD says that M31's nucleus has very low level of activity. Interesting.
