This shot is actually composed of 51 individual Hubble exposures, in addition to elements from images from ground-based photos. The giant spiral disk of stars, dust, and gas is 170,000 light-years across or nearly twice the diameter of our galaxy, the Milky Way. M101 is estimated to contain at least one trillion stars with approximately 100 billion of these stars similar to our Sun in terms of temperature and lifetime. M101 lies in the northern constellation Ursa Major at a distance of 25 million light-years from Earth.

I’ve always been impressed by images of M101. I think it looks like a well figured piece of marble, however improbable that might be. It makes terrific wallpaper too.

There are three colours, Ten digits and seven notes, its what we do with them that’s important. Ruth Ross

For God so loved the world that He gave His only begotten Son, that everyone believing into Him should not perish but have eternal life.
