New weather images show the highest resolution ever on Jupiter from Earth-based telescopes.
Astronomers are interested in learning more about Jupiter's atmosphere because it may support current ideas on how our solar system formed.
Striking images of the giant gas planet reveal a glowing jack-o-lantern where dark colors are actually holes in the cloud cover in the famous Great Red Spot.
Infrared light beams out of those gaps like the candlelight from inside a jack-o-lantern.
In addition to the ground-based Gemini Observatory in Hawaii, combining imagery from the space-based Hubble Telescope along with the Juno spacecraft orbiting Jupiter, uncover some of the mystery about the mightiest storms in our solar system swirling on Jupiter.
Lightning strikes, and some of the largest storm systems that create them, are formed in and around large convective cells over deep clouds of water ice and liquid.
By combining observations captured at almost the same time from the two different observatories, astronomers were able to determine that dark features on the Great Red Spot are holes in the clouds rather than masses of dark material.
While scanning the gas giant for gaps in cloud cover, Gemini spotted a telltale glow in the Great Red Spot, indicating a clear view down to deep, warmer atmospheric layers.
“Similar features have been seen in the Great Red Spot before,” said Glenn Orton, team member at NASA’s Jet Propulsion Laboratory. “But visible-light observation couldn’t distinguish between darker cloud material and thinner cloud cover over Jupiter’s warm interior, so their nature remained a mystery.”
