NGC 1700: An elliptical galaxy about
160 million light years from Earth.
Caption: Chandra's image of NGC 1700
shows a flattened oval of multi-million degree gas. Low-energy
X-ray data reveals a giant inner disk 90,000 light years in
diameter. An analysis shows that it is rotating and appears to
be cooling. The existence of a large, rotating disk of hot gas
suggests that NGC 1700 was created by the merger of a rotating
spiral galaxy and an elliptical galaxy containing hot gas.
