NASA'S Chandra X-ray Observatory marks four years of amazing space discovery
Four years ago, the Chandra X-Ray Observatory began operation and has been orbiting Earth ever since, capturing dramatic, never-before-seen-images.
Delivered to space by the Space Shuttle in 1999, Chandra was the largest and heaviest Shuttle payload in history - the length of a bus weighing 6 tons.
It travels one-third of the way to the Moon during its egg-shaped, Earth orbit every 64 hours.
Shedding new light on black holes, Chandra has recently observed the life-cycle of X-ray jets produced by a black hole, and revealed two large black holes in the nucleus of a bright galaxy.
Over the past 12 months, Chandra also discovered a spectacular jet in the Vela pulsar that whips like an uncontrolled fire hose at about half the speed of light.
Through Chandra, scientists received their first look at X-ray images of Mars' upper atmosphere.
One scientist has devoted almost 30 years of his life and career to the Chandra project.
Talk with him about the latest discoveries, and what lies ahead for Chandra.
