With a smorgasbord of celestial targets to choose from, it wasn't easy picking a portrait to celebrate the Hubble Space Telescope's 20th anniversary.

NASA has warned the crew of space shuttle Discovery to expect rain delays as they prepare to return to Earth after their visit to the space station.
