Yes there are many stars that are in astronomically close proxcimity to each other. Within 1/4 light year and closer. these stars tend to orbit each other around a central point (much like electrons orbit the nucleus of an atom but without the nucleus). They orbit a gravitationally centralized point...

Lurker, We have detected over 150 extra solar planets most of which orbit stars in rural neighborhoods. The problem is that we detect these by the wobble that gravity creates as the orbits interract. Unfortunately, stars that exist in areas where there are many in close proxcimity, are each in turn ...

Aqua, Intergalactic magnetic fields?!!! A very interesting concept. It would be interesting to send some probe out to the point where you could view any possible galactic magnetic field. If there is one, and it could be measured, then one might have proof of an attractor mechanism that would functio...

Updated Pleadies image
I have an updated Pleadies image that was modified to remove the telescopic "Twinkle" artifact. It is the same image that appeared on APOD earlier. http://www.imagehosting.us/index.php?ac ... nt=1057595

Well,
Another one bites the dust. look at the LASCO-C3 and LASCO-C2 mpg files. Another cool sight. It will probably only appear 01-06-06 and 01-07-06. so look fast.

Empeda2, I think that they are counting total distance traveled in any direction. if the rover rolls foreward 20', then finding no clear path to travel backs up 18' then turns and rolls foreward 10' it has only traveled 12' from its original point of origin but the odometer indicated it has traveled...

I believe it is correct given that it spent all thet time scoping out Eagle crater and then Endurance crater (wasn't Burns cliff interesting) and the fact that opportunity spent weeks trapped in a sand dune then traveled in 30-40' segments.. When you travel no more that approx 100' per day (average)...

I would think it would be possible (as Empeda states though there would need to be a gas cloud of sufficient quantity with a central mass large enough to start the gravitational crunch nnecessary to cause a star to evolve.) If it weren't possible, then the first stars might not have formed in the be...

Also the horse head would be quite naked eye visible. This is ...

I would imagine that it would be affected as far as gravity warping the space around the earth. The earth's gravity acts to pull the moon ( to a small degree) around it in a certain direction. (are there any (many) moons orbiting planets in a retrograde orbit?) If the rotation increases then the war...
