Astronomers unveiled one of humankind’s most spectacular views of the universe as captured by Hubble. The Cone Nebula, M17 is pictured here. As spectacular as the central subjects of the photographs are, the background is of critical importance to astronomers. What appear as jewel-toned pinwheels, ovals and diamonds on the blackness of space are actually faraway galaxies. The sharpness of these images will allow scientists to study the furthest reaches of the universe.
