Jupiter's auroras are among the most powerful in our solar system, and they appear when high-energy electrons stream across the gas giant's magnetosphere and pour into the upper atmosphere to ...

Jupiter's aurora drove a heat wave as wide as 10 Earths. Swirls of green and red appear in an aurora over Whitehorse, Yukon, on the night of September 3, 2012.

Jupiter's mysterious "energy crisis" that has puzzled astronomers for 50 years could be caused by auroras, new observations suggest. The largest planet in our solar system has long been known to ...

On Jupiter, Fourth of July fireworks last year-round. New images from the Hubble Space Telescope reveal a new feature of the gas giant: brilliant blue auroras. “These auroras are very dramatic ...

In the case of Jupiter, many of the electromagnetic waves thrown off by its auroras are x-rays—invisible to human eyes, but key to understanding more about how auroras on Jupiter form.

Jupiter should be frigid, but massive areas of its upper atmosphere are far hotter than anywhere on Earth. Auroras on Jupiter Seen Spawning Massive and Extreme Heat Waves - CNET X ...
