Astronomy Picture thread

It's the Astronomy picture thread, not the "Astrology and Various Mythological Brick-a-Brack thread"

So much for my next intended post of the Mutara nebula.

Anyhoo... The Virgo Supercluster. We're in there somewhere! Well, we're not actually in THAT shot, but we're in the cluster.

"Approximate size of earth for comparison"

Is the centre of the Earth (in that photo) in the same plane as the center of the sun (the computer screen)? Or is the 'closest edge' of the spheres the computer screen? Is the Earth that tiny because it's been placed really far away (because it's the same plane as the sun)?

I wonder if it's even understood what I mean? What I mean is that the picture is confusing because I don't know if the image of the Earth is closer than the image of the Sun.

Well, the sun's radius is about 100 times Earth's so that should give you a general idea. (Note that means the sun has 10,000 times the surface area and 1,000,000 times the volume)

Alberio - actually just saw this about a month ago at a public showing at an observatory just west of Mpls. Very cool to see both stars thru a high-powered telescope.

It's the base of the Northern Cross, or more commonly known as the "beak" of Cygnus the Swan.

I found this image of The Pleiades Star Cluster wonderful. So, dream-like and ethereal.
