Where Can I Find Multispectral Images of the Earth?

Where can I find pictures of the Earth taken from different frequences of light other than the visible spectrum? There has to be X ray pics of the planet.

You mean taken with the giant, planet sized x-ray imager?

Well I have seen x ray images of the sun. So I assume they can take the same picture of the earth. I looked around and could not find these pics.

To have a reasonably measurable intensity in the x-ray region, I believe you'd need temperatures in excess to 10⁵K. You get that easily from the hot parts of the sun, but not so much from the earth.

The Earth radiates primarily in the IR regime. Have you looked within the NASA website? They've been measuring the Earth's emission spectrum for lots of years now.

Wien's displacement law, $$\lambda_{max}=\frac{b}{T}$$, shows the relationship between the temperature of a body and the frequency of the radiation it re-emits. $$\lambda_{max}$$ is the peak wavelength in meters, $$T$$ is temperature in Kelvin, and $$b$$ is Wien's displacement constant, which is 2.897 x 10$$^{-3}$$ m K.

If you plug in the Earth's surface temperature, you get wavelengths in the infrared.

Since it isn't putting out any x-rays it would be invisible to an x-ray camera.

Many of the NASA satellites are pictures at other spectrums (i.e. they're not actually pictures, they're visualizations of various sensor data.)

GOES is a good example: http://www.ghcc.msfc.nasa.gov/GOES/goeseastconusir.html
