Starship Asterisk*

Given that they are more distant objects, I wonder: are we actually seeing redshift in the visible spectrum of these distant objects? Anybody know? I've seen that explanation in a caption once or many times, but I'm not qualified to confirm it's the correct one. Perhaps we're seeing the combined ef...

This is certainly a valid point, however, it doesn't apply universally to everything we call jets, c.f. Messier 87. Are you saying the M87 jet is not a particle stream? Well I guess I sort of am, but that's just sloppy expression from my part. The remark about Messier 87 was made to emphasize the f...

I believe it is a jet, but it could be a tidal tail too. Oh, Ann, Ann, Ann. 1) Jets shoot perpendicularly out of the center of galaxies not tangentially out of their arms and they usually have counter jets shooting out the opposite direction . 3) "The intruder galaxy itself can be seen through...

It's a striking image. Any idea if the nebulosity that seems to be centered and normal to the galactic plane of the largest background galaxy is a jet of some sort, or another gravitational tail / stream ?

Does anybody have an idea how these are caused? Or did we find the Fleet of Worlds?

I suppose they were caused by a pencil There's also a pattern for 5, and the one for 7 appears in
several places.

Look a lot like the newfound (Nov2008) (yet to be officially named AFAIK) 'Riikonen arcs':

Culprit would be a flattened hexagonal ice crystal.

Can anyone tell me the names of more of the objects in the picture. Names of Stars, etc.... I am trying to identify the region of space in Starry Night. ftp://ftp.ncsa.uiuc.edu/cosmic/data/mark/GCSchematicscan2rot.gif ftp://ftp.ncsa.uiuc.edu/cosmic/galcenter/GC-P-BCD.med.jpg http://apod.nasa.gov/ap...

Well, quasars are (at their core) black holes, so of course there are very high strength gravitational fields present. But I think you are correct about the radiation source. Since the energy we see is actually coming from interactions well outside the event horizon, gravitational redshift is a sma...

So.

Was this a new find or did someone come up with a catalogue id?
