Excuse me barging in on your post, Markusfix, but it's the only way I can write an introduction to this topic that will appear at the top, not the bottom.

There have been about 6 or 7 lovely Planetary Nebulae and Supernova Remnants threads and I decided to bring them all together. Some of it may appear a bit disjointed, but few of them overlap in their dates. Enjoy! :)

Update! LizPeter have kindly provided a list of all the various reference numbers the nebulae have, so you can now see if another grain of dust in your nebula has already been posted. Check here.

That looks like a Planetary Nebula to me.

I had a quick look in Simbad. Turned out to be M97, The Owl Nebula, one of the brighter planetary nebulae in the sky. Both SEDS and Wikipedia have some info about it.

I just got a scolding from Kate and Chris for my lacking sense of wonder.

If it's not at least a million solar masses, I just don't care.  ;)

Here we are on our single world, and we haven't even finished exploring it. Yet we can strive for a time when we are part of the bigger picture itself and no longer just viewing it.

Owl, eh? That makes it seem so cute! Have I been spending too much time here, if I'm starting to think of galaxies as "cute"?  ::)

Wow! You found a planetary nebula. I think this is the first one yet posted to the forums. Notice the spherical symmetry, and the dwarf star in the center:

This ought to be nominated for the image of the day!

According to Zookeeper Kate, that is a supernova remnant - she posted it on Wednesday. Its absolutely amazing!

Wow that's a neat one ! I am not sure either but I think you are right about some kind of explosion . I don't think it a Supernova remnant because it is to symmetrical but maybe a precursor ?

I'd call it a supernova.
The high density middle and the outward sphere certainly indicate that.
But, it's so large. The redshift indicates a great distance, but it still fills up a large area.
this is a great picture, doubtless, no matter what it is.
