"High-resolution X-ray images of Eta Carinae from 1992 (left) and 1994 (right).
X-rays are emitted from hot gas in an oval shell around Eta Carinae. A bright
source of high-energy X-rays at the center of the shell is apparent in the 1994
image but not in the 1992 image. The inset shows a picture of Eta Carinae and
the homunculus from the Hubble Space Telescope's Wide Field Planetary Camera 2.
Eta Carinae appears as a dark spot at the center of the HST image, and the
homunculus as an oval-shaped nebula around the star. The boxes in the X-ray
images show the location and scale of the HST image. The bright source to the
top of each X-ray image is an X-ray emitting massive star close to Eta Carinae.
This material was presented to the American Astronomical Society meeting in
Pittsburgh, PA on June 13, 1995." PHOTO CREDIT: M.F. Corcoran, ROSAT Guest
