November CAS Meeting

November 2 @ 7:00 pm 9:00 pm

The X-Ray Sky in High Definition

Probing the High Energy Universe with the Chandra X-ray Observatory

Dr. Pat Slane

Director of the Chandra X-Ray Center

X-ray astronomy is a product of the space age. Possible only from viewing platforms above the atmosphere, the first celestial X-ray source other than the Sun was discovered less than sixty years ago.

Following fresh on the heels of this discovery, with X-ray astronomy just barely in its infancy, an almost unimaginably-bold proposal was put forth to build a visionary space-borne observatory based on X-ray optics whose resolution and sheer size represented leaps by orders of magnitude over any such mirrors ever built. Following a series of smaller, but ever-improving X-ray observatories, this vision was fully realized in July of 1999 with the launch and deployment of NASA’s Chandra X-ray Observatory.

With operations still underway, following more than two decades of observations in which breakthrough science has been carried out on objects ranging from nearby planets to distant quasars, I will look back on the development of Chandra and provide a summary of some of the most exciting results from its ever-increasing scientific legacy. These include breakthrough discoveries on the births and deaths of stars, the activity of black holes, and the structure of galaxy clusters.

The meeting this month will be a Hybrid Meeting.  We will meet in person at the University of Virginia’s McCormick Observatory and the meeting will also be conducted in a Zoom session with Zoom login details sent out to all CAS membership.


If the night is clear, we will open the 26″ McCormick Telescope for viewing after the meeting.
