okay you astro gurus - here's a question or two
If all the stars in the sky that we can see are in the milky way galaxy, which
part of the galaxy are they in? our own spiral arm?
or can we see outside our own spiral arm?
we can see outside our spiral arm, but we can't see the far side of our galaxy.
And if I was looking through a large telescope - say a 25" Obsession for
example - would I then be able to see objects (stars, PNs,
clusters etc) that are beyond the milky way galaxy? Or does it take a Hubble to
see that far? Clearly we can see other galaxies but
can we ever see inside those galaxies to the stars and other objects of those
galaxies??
we can see OC, GC & neb in the LMC & SMC, which are nearby galaxies. also neb
in M33.
These two web sites are good.
