Constellations : Wonders Within

Four hundred years ago, Galileo turned his telescope to the sky and forever changed how humanity views its place in the cosmos. Since then, astronomers have been building telescopes both in space and on the ground -- to help further our understanding of the Universe. This series of posters represents some of the most dramatic images made by combining data from the best of modern telescopes.

These images can be found in the "From Earth to the Universe" exhibit that is currently on display around the world as part of the International Year of Astronomy 2009, a global effort to promote appreciation of the night sky and the science it contains.
