Q:
What kind of radiation is used to gather information on black
holes, and how?
A:
The Chandra X-ray Observatory and other X-ray telescopes gather
information on black holes by studying the X-radiation from hot
matter swirling toward a black hole. Gamma ray telescopes cannot
pinpoint the sources as accurately, but can obtain important
information about even higher energy radiation from matter in
the vicinity of black holes. See our listing under "Black Holes"
in the Field Guide at http://chandra.harvard.edu/xray_sources/black_holes.html
