In this view of a vortex near Jupiter’s north pole, NASA’s Juno mission observed the glow from a bolt of lightning. On Earth, lightning bolts originate from water clouds, and happen most frequently near the equator, while on Jupiter lightning likely also occurs in clouds containing an ammonia-water solution, and can be seen most often near the poles.

In the coming months, Juno’s orbits will repeatedly take it close to Jupiter as the spacecraft passes over the giant planet’s night side, which will provide even more opportunities for Juno’s suite of science instruments to catch lightning in the act.

Juno captured this view as Juno completed its 31st close flyby of Jupiter on Dec. 30, 2020. In 2022, Citizen scientist Kevin M. Gill processed the image from raw data from the JunoCam instrument aboard the spacecraft. At the time the raw image was taken, Juno was about 19,900 miles (32,000 kilometers) above Jupiter’s cloud tops, at a latitude of about 78 degrees as it approached the planet.

JunoCam’s raw images are available for the public to peruse and process into image products at https://missionjuno.swri.edu/junocam/processing.

      Did you know the Great Red Spot is shrinking? From Wikipedia:

      In the 21st century, the Great Red Spot has been observed to be shrinking in size. At the start of 2004, its length was about half that of a century earlier, when it reached a size of 40,000 km (25,000 mi), about three times the diameter of Earth. At the present rate of reduction, it will become circular by 2040. It is not known how long the spot will last, or whether the change is a result of normal fluctuations.[12] In 2019, the Great Red Spot began “flaking” at its edge, with fragments of the storm breaking off and dissipating.[13] The shrinking and “flaking” fueled speculation from some astronomers that the Great Red Spot could dissipate within 20 years.[14] However, other astronomers believe that the apparent size of the Great Red Spot reflects its cloud coverage and not the size of the actual, underlying vortex, and they also believe that the flaking events can be explained by interactions with other cyclones or anticyclones, including incomplete absorptions of smaller systems; if this is the case, this would mean that the Great Red Spot is not in danger of dissipating.[15]

      Considering the Great Dark Spot of Neptune has disappeared (other other dark storms have appeared), I think we are lucky enough to have observed such a massive storm on Jupiter for hundreds of years

      So have you ever heard the argument that Jupiter is our protector? That theory has changed slightly in recent years and it’s more likely jupiters gravity well has flung more shit at the inner planets than really shielded it.
