Stars are a photo from the Hubble telescope on a 2D panel. Earth is made from 2 spheres, one for a high quality map texture & one for the clouds map. Clouds are from a real cloud texture with transparency and bump. Moon is made from 1 sphere and a moon texture with a bump map. 5 radial lights & Sun light on. Built & rendered in Bryce 5. Rendering time 28min at 2000 x 1399 pixels. Bryce document size 146 MB. Earth outer glow, sharpening image and signature in postwork. You can find this great Hubble model at TCM by Jestr (Hubble with a new texturing by me) Earth and Clouds textures by Space-Graphics, Moon texture by Solarviews. Thanks very much for your stuff. Thanks for viewing and all comments are appreciative. Have a great relaxing day and Happy Christmas to everyone from the ISS!
