APOD: Ultraviolet Andromeda (2010 Oct 27)

[Meneldur]

I too am curious about what appears to be three small rings joined together at about 4 o'clock on the UV image. It looks like a very curious formation, or could be nothing at all and just a trick of optics.

Thank you! Very interesting stuff.

What is that at the bottom right (sandwiched between the stars) -- looks like two hollow balls of light -- which are readily seen in UV, but completely disappear in optical light. Nothing else in the photo gives the appearance of a hollow ball of light. except these two.

Art! We've got an ultraviolet image for once. Even better and even more unusual,
it's an ultraviolet image of a spiral galaxy and not, say, of the Sun.

And hey, you start talking infrared???

Ah, I don't know, Art. She has her ultraviolet sides after all.

Let's just help stamp out all those little infrareddies out there, okay?



An infrareddie about to turn Andromeda all red! Let's stamp him out!

Well, good thing we have brave Perseus to defend our Andromeda!



He may wear red and yellow here (an unfortunate choice of colors, Perseus dear), but he sure has a lot of ultravioletties wrapped up in that red skirt of his! (And he's got a truly petrifying accessory, too, but that's another matter.)

I enjoy the visible wavelength comparison in this APOD… technology drills beyond the visible revealing the "monsters" and chemistry to those with a trained eye.

I am grateful that astronomers are generous with their discoveries. I see the APODs as art in science and science in art. It’s no wonder there are so many references to art here.
