Starship Asterisk*

Awesome.

Naaah. I was just given that nick by the moderators, because 4725 Angstroms is blue wavelength, and I love blue things. Love it! Deep rich blue is a beautiful color. Speaking of which, I once worked on the same worksite as David Malin. Probably have walked passed him, possibly even talked to him. I...

why don't these three system all come together and become one? I think you will find that is exactly what they are doing ..... process taking about 1 billion years. If you look closely, you might find that the two distant galaxies of the three on the left, are in fact two galaxies each, both in the...

I don't see where you get this talk of 7 times larger. If these Stephan's Quintets are 300 million ly away and the galaxy in front is 40 million ly away and they appear the same size than the former are 260 million light years farther away than the latter. So if they were all 40 million ly away the...

Ann 4725 Angstroms? Hydrogen, Helium, Cerium, Molybdenum, Rhenium, Tungsten, Yttrium? Neon?

Bruce, Sorry Ann, but that's not a likely assumption, since dark matter out weighs baryonic by about three to one. Going just by appearance alone can lead to wrong conclusions, since there is usually much more that is unseen than that which is seen. Thanks for that. Good point. With today's APOD, an...

Ann, thank you for such a considered response. Very much valued. The Malin 1 galaxy would seem to be the upper limit. 650,000 light years diameter is staggering. Your information and direction helps me with gaining a sense of scale of the mass range for spiral galaxies. Thank you so much for that. :D

I want to ask about the estimate stellar mass of NGC7320 vs the other more distant galaxies. (If known.) The more distant colliding spiral galaxies are about the same angular size as NGC7320, even though much more distant. Given the ratio of distances is 300/40 (Million LY) to my understanding then ...

Ah, yes thanks, lower right, not lower left. I figured the relevancy of this picture was to identify evidence of the moving body discovered by showing the short movement trail. Hence I identified and look for elongated images lower left, where in fact the real object is the stationary spherical brig...

Um, I see two elongated (moving in the time of the photographic exposure) down lower left. So which one is it?

we are equally blessed here upover !!! Pleased to hear good topside as well. As has been the case over the last century, including through the cold war era, may the astronomical community and its supporters on this small spherical (and non-transparent) world in an infinite universe continue to work...

neufer - perfect!

GG congrats. I suggest there may be interested in your equipment specs for the shooting session. Looking very closely at the back tail fin ...... is that a possum or a polly from Canberra clinging ... I would give time of photoshoot first (those keen can try and calculate your position), then give l...

Sanskirt is what immediately came to my mind. What ever it is I see beauty in it, that is all I know. Perhaps we should not ask further.

Cheers,

Duh. I'm posting in "regular member" mode. Also, I do not consider this mod-ship a "gift from Gods", I am not paid for this, and I usually use it to enforce rule 5 and/or keeping this place clean according to my likes to "place cleanness". If somebody doesn't like the ...

The Voynich Manuscript I believe is the source of Makc's signature, I bet he would love someone to translate it for him!

Smiles and laughter - and oh yes, I needed some of that this morning. Ta!

there's 9 pages long thread on dark matter. Don't you think it fits there better. makc, moderator... I believe I am asking a legitimite astrophysical question directly related to the release of this specific photo. Yes, you do. That's why your thread isn't locked, right? But, it's just a common thi...

Disclaimer: I am not a scientist. I probably know only enough to be dangerous. But, I gotta say, what a cool site. One thing I noticed right off the bat, which to a lot might seem fairly obvious, is that the center of the Cartwheel galaxy omits visable light and infrared but no x-rays. Does this me...

there's 9 pages long thread on dark matter. Don't you think it fits there better. makc, moderator. Thanks. Had a look at the post on dark matter you refer a little further down. Actually I did miss it. I did not look that far as I thought with the Cartwheel picture only just released that the first...

As suggested in explanation, x-ray sources are likely blackholes, some post supernova, some ejected in consequence of galaxy collission. Noting some x-ray sources appear to have been ejected into extra-galactic space, and given x-ray emissions are a product of surrounding material being sucked into ...
