This is a picture of Jupiter taken in infrared light (light beyond red).
Jupiter gives off a lot of this type of light. This is the same light that
people give off because their bodies are warm.
In the picture you can see
places where a lot of infrared radiation is given off by Jupiter (bright white in the
picture) and then other places where something is keeping the radiation from
reaching us. These places appear black.
If you look at Jupiter in visible light,
you will see that it is covered in clouds arranged in bands.
The cloud bands that you see on
Jupiter block the infrared radiation
from leaving the planet. Holes in the clouds let heat through from the deeper and
hotter parts of Jupiter's atmosphere.
Click on the picture. This picture
shows Jupiter in infrared light and next to Jupiter two people whose pictures were
also taken in infrared light. The parts of the people not covered by clothes
are sending off a lot more infrared light than those parts covered by clothes. The
clothes on the people and the clouds on Jupiter both block the infrared radiation.
