X-Ray Spectra Activity

Working with x-rays at home would be dangerous, so this activity from the Exploratorium provides a safer simulation. You can see the effect of x-rays using only household items.

APOD: X-Ray Moon

What you see above is two images of the moon in x-ray light as it moves in front of an x-ray binary star system. The binary is visible as a yellow dot in the first image before being obscured by the moon in the second. Learn more about this image here. To see another image of the moon in x-ray light, see APOD: X-Ray Moon.
