This image shows the first X-ray picture ever taken of a comet. In the
image, the X-rays from the comet seem to come from a crescent-shaped region
on the sunward side of Comet Hyakutake. Unlike the visible light from the
comet, the nucleus or solid body is not only not the brightest point in the
comet. In fact, the scientists say, the nucleus does not show up in the
X-ray.
