Red in Jupiter's Spot Not What Astronomers Thought
from Wired
The best thermal images of Jupiter's Great Red Spot yet captured have revealed surprising weather and temperature variation within the solar system's most famous storm.
The darkest red part of the spot turns out to be a warm patch inside the otherwise cold storm. The temperature variation is slight: "Warm" in this case translates to -250 degrees Fahrenheit while cold is an even frostier -256 degrees F. But even that difference is enough to create intriguing internal dynamics.
"This is our first detailed look inside the biggest storm of the solar system," said Jet Propulsion Laboratory astronomer Glenn Orton, who led the new study to be published in Icarus.
