Old Faith-Full Moon

Old Faith-Full Moon - The picture combines the regularly occurring lunar phase with Old Faithful Geyser, named for its dependable erruptions. Shining on the well-known geyser's towering pillar from behind, the moonlight creates an eerie halo surrounding convoluted shapes. The Full Moon itself is bright enough to be seen through the dense swirling steam near the top. — at lmage Credit: Jimmy and Linda Westlake/NASA (Yellowstone National Park - Sept. '09).
