It's the Day of Zeus / Jupiter's Day / Thorsday! ⚡

"The surname Homagyrios (the Assembler) was given to #Zeus because in this place Agamemnon assembled the most eminent men in Greece, in order that they might consult together how to make war on the empire of Priamos [of Troy]."
Pausanias, Description of Greece 7.24.2

Cyclones at Jupiter's North Pole

Explanation:
Why are there so many cyclones around the north pole of Jupiter? The topic is still being researched. NASA's robotic Juno mission orbiting Jupiter took data in 2018 that was used to construct this stunning view of the curious cyclones at Jupiter's north pole. Measuring the thermal emission from Jovian cloud tops, the infrared observations are not restricted to the hemisphere illuminated by sunlight. They reveal eight cyclonic features that surround a cyclone about 4,000 kilometers in diameter, just offset from the giant planet's geographic north pole. Similar data show a cyclone at the Jovian south pole with five circumpolar cyclones. The south pole cyclones are slightly larger than their northern cousins. Oddly, data from the once Saturn-orbiting Cassini mission has shown that Saturn's north and south poles each have only a single cyclonic storm system.

Jupiter, 31 august 2024

Three images of Jupiter and the galilean moons.

All three have been acquired with the same setup and slightly different exposure settings. The first one show Jupiter and the four Moons, while the field of view gets narrower in the other two.

The cloud bands are visible, not in great detail though. Same for the Gread Red Spot, which is starting to appear from the planet’s limb.

For the acquisition details and the full resolution images, follow the link to the gallery localvoid.net/2025/03/08/jupit

Planets are formed from protoplanetary disks, spinning clouds of dust and gas that are the perfect ingredients for #planet formation.

A fresh look at past data reveals that #exoplanets with masses similar to #Jupiter formed much sooner than previously thought.

New results provide information about the early timing of accretion—the process of accumulating a large amount of gas and dust to make large #planets.
