The sky looks quite different when viewed at different wavelengths of the
electromagnetic spectrum.
The figure on the left shows an image of the sky in the direction of the
center of our galaxy as
observed in the infrared portion of the spectrum. Click on the figure

The figure on the right shows an
image of the sky as observed in the gamma-ray portion of the electromagnetic
spectrum. Click on the image for an explanation and larger version.
Here is
another gamma-ray image
of the sky, this time showing pulsars in the vicinity of the Crab Nebula.
Many objects emit X-Rays. The most important observations of X-Rays
are probably for distant and violent
objects, but even local
objects like the sun and moon emit X-Rays. The adjacent
image shows the
Sun in the X-Ray band on an active day. Click on the image to get a larger
