Skywalk at the West Rim of the Grand Canyon. It's suspended feet above the Colorado River allowing one to have a 720 degree view, through the glass floor, of the Canyon!---The Grand Canyon is on my Bucket list.
The General Sherman, Sequoia National Park, California - American National Parks. It is a very beautiful national park and this particular tree is literally gigantic though the pictures may not show it.
This image from Nasa's Spitzer Space Telescope shows a stellar nursery containing thousand of young stars & developing protostars near the sword of the constellation Orion. I heart the Spitzer space telescope.
