Warnings: The True Story of How Science Tamed the Weather by Mike Smith tells the story of our storm warning system. See our online store book collection.


Neptune, the eighth and furthest planet from the Sun, is a very cold place. Its bluish color is caused by small amounts of methane gas in its atmosphere. The planet has moons and a very narrow, faint ring system.

Neptune's <a href="/php/tour_test_sqli.php?page=/neptune/lower_atmosphere.html&edu=elem">atmosphere</a> shows
a striped pattern of
<a href="/php/tour_test_sqli.php?page=/neptune/atmosphere/N_clouds_overview.html&edu=elem">clouds</a>.
This cloud pattern is very similar to that of
<a href="/php/tour_test_sqli.php?page=/jupiter/jupiter.html&edu=elem">Jupiter</a> and
<a href="/php/tour_test_sqli.php?page=/saturn/saturn.html&edu=elem">Saturn</a>.
Neptune even has a <a href="/php/tour_test_sqli.php?page=/neptune/atmosphere/N_clouds_GDS.html&edu=elem">Great Dark
Spot</a> similar
to Jupiter's <a href="/php/tour_test_sqli.php?page=/jupiter/atmosphere/J_clouds_GRS.html&edu=elem">Great
Red Spot</a>.
The Great Dark Spot of Neptune is thought to be a hole, similar to the hole
in the <a href="/php/tour_test_sqli.php?page=/earth/Atmosphere/ozone_layer.html&edu=elem">ozone layer on
in the <a href="/php/tour_test_sqli.php?page=/physical_science/chemistry/methane.html&edu=elem">methane</a> cloud
deck of Neptune.<p><small><em>Image courtesy of NASA</em></small></p>
