Starship Asterisk*

I think that "if you were in it" you wouldn't "notice it" as I read about this subject concerning the Orion nebulea.

"April 24 2008 Cygnus without stars" apod made me realize that a bright nebulae, once considered as a single object, (as seen with small telescopes) like the North America Nebula is just a lighted part of a huge "cloud" of glowing hydrogen atoms.

Hi, when I clicked on the black arrow on February 28 pic. (ISS: Sunlight To Shadow) my computer gave me the BDS ( Blue Death Screen) it happened using Firefox and Windows Explorer. It seems that my graphic card driver was involve but my computer is working fine except this event. So did this happene...

http://heasarc.gsfc.nasa.gov/docs/objects/heapow/archive/compact_objects/spinning_bh.html So it seems that the possibility of spinning and non-spinning black holes exist. What interest me is to imagine the structure of the gravitional fields these two kind of objects would have if represented as if ...

Well, "like water swirls representations" are caused mainly by rotation... so first question:
Neutron stars rotate often at very high speed...so at what speed do black holes (or the singularity within) turn?
Second:Does the possibility of a non-turning black hole exist?

Hi, black holes are always represented like "water" swirls in space but since their enormous gravitationnal forces are effective in all directions what would be their true representation?

Hi, Harry, "salut à tous tes compatriotes (from Quebec) " ...if I'm right about the "Ring Nebula's" real shape, it could be simulated based on what we see with computers !

I've always guessed that the "Ring Nebula" if viewed from a different angle (that would be only an option in space) would have an hour-glass shape as many planetary nebulas do.., it looks like a ring maybe because we see it at a particular angle, ie: front view!

Hi, on apod Oct. 27/97 and lot of others we can see two galaxies colliding. My question is: What are the probalities of stars colliding when these events occur considering the angle of collision? Thanks...but what about the way they collide...I mean: what if the collision happens for each galaxy to ...
