"In March 2002, astronomers were keen to try out the Hubble orbiting telescope's spiffy new camera. The camera, installed by Shuttle astronauts during "five of the most challenging spacewalks ever attempted" was 10 times better than the telescope's old camera.On April 2nd, Hubble turned to the Cone Nebula, a gaseous pillar in the Milky Way 2,500 light years from Earth. After a 3.4 hour exposure, the telescope produced the beautiful image seen on the left."
...wow.
