While inside in a bookshop in Cork today, I happened to notice that Linux Format magazine (50th issue, probably the February one) had a review of astronomy software. Naturally, I had to see was Celestia listed!
Good news...!!
From a lineup including:
Nightfall, Starplot, Kstars, Xsky, Xephem, XPLNS, Celestia and Stellarium, we came 1st, with 9/10!

Features: 9/10
Ease of Use: 8/10
Documentation: 9/10 (Thanks Don G & Frank!)

Performance: 8/10
"For a generation of users who cut their space-faring teeth on Elite, this is Astro-simulation at its finest!"
There was a roughly half page article with screenshots, and then some more shots from the celestiaproject.net/celestia homepage overleaf. Unfortunately, these were incorrectly labelled as coming from Stellarium.

It also had a free DVD with the magazine, with all the software they've reviewed included on it. (There's a LOT of stuff on there; things that i've heard people on the forum mention like OpenOffice.org, mySQL, GIMP, and things like Apache as well..) Even though I don't have linux, I bought it anyway to see what addons they included with it. They put in everything from Fridger's texture foundry, numberedmoons.ssc (I can't tell which revision), shrox's MGS and Mars Odyssey models.
Not too bad...!
