15year HARVEY'S VOYAGE

On April 20, 2014, Harvey Tananbaum stepped down after 23 years as director of the Chandra X-ray Center (CXC). This event was duly noted in various press releases, but its significance may not have been widely appreciated.

By almost any measure Harvey has been one of the most outstanding directors ever of a major astrophysical observatory. He was director of Chandra for longer than any other director of a world-class telescope. In fact, he became director of Chandra in 1991, 8 years before it was renamed from AXAF (Advanced X-ray Astrophysics Facility) to Chandra upon its successful launch in 1999.Full Story

Chandra in 2012: A Teenager in Space
In July of 2012, Chandra completed its 13th year of operation, making it a teenager. That is young in human terms, but it is getting up there for an automobile, and could be considered a "senior citizen" for a spacecraft of Chandra's complexity. Full Story.

Look Back Time -- Remembering Franco
The finite speed of light means that we must always be out of date, no matter how hard we strive to keep up with the times. The term look-back time refers to the time in the past when the light we now observe from a distant object was emitted. Full Story.
