Hubble returns to 'old friends'
The Hubble Space Telescope, which in 2015 completes 25 years in orbit, has gathered dramatic new views of two well-known celestial objects. Revisiting one of its earliest and most famous photos, a new view of the Eagle Nebula shows its "Pillars of Creation" in more detail than ever before. And a composite of 13,000 shots of our neighbouring Andromeda Galaxy becomes the telescope's biggest ever image. Both were unveiled in Seattle at an American Astronomical Society meeting.
