Astronomy Picture of the Day

Explanation: Get out your red/blue glasses and check out this close-up of space walking astronaut John Olivas outside the International Space Station. Carefully constructed from two photographs (ISS020-E-038481, ISS02-0E-038482) taken during space shuttle orbiter Discovery's latest visit to the orbiting outpost, the 3D anaglyph creates the the strong illusion that you can actually reach out and take his hand. The photographer, fellow spacewalker Christer Fuglesang, along with ISS structures and planet Earth's horizon, are reflected in Olivas' helmet visor. Last Friday, the two returned to Earth along with the rest of Discovery's crew, landing at Edward's Air Force base in California.
