✨🔭 New observations of #Ganymede 🌖reveal a surprising similarity between the #auroras 🌌 on the #SolarSystem's largest #moon and those on #Earth 🌍. A team of space physicists has obtained new results suggesting that the fundamental physical processes that generate auroras are common to different celestial bodies.

Fig. 1. Top-left panel: Projection of Ganymede’s FUV aurora acquired by Juno-UVS on June 7th, 2021, from 16:52 to 17:04 UTC. We used the
Ganymede-centered Phi-Omega (GPhiO) frame of reference, with z parallel to Jupiter’s spin axis and y toward Jupiter; x completes the right-handed
system. The brightness is integrated over 130.4 ±1.5 nm and 135.6 ±1.5 nm. The green lines show the predicted OCFB (Duling et al. 2022). The
background shades of gray (from dark to light) represent the surface illumination: surface that is not illuminated, only sunlight reflected by Jupiter,
only direct sunlight, and both reflected and direct sunlight. The green and red bars mark the direct and reflected illuminations, respectively. The
red dot around 90◦ is the downstream direction, while the red cross at−90◦ is the upstream direction. The orange dot at 0◦ and the yellow star at
∼–40◦ are the direction to Jupiter and to the Sun, respectively. The numbers 1–9 mark successive Juno spins. The green cross is the projection of
Juno’s closest approach. The orange boxes labeled a-g are reproduced in the seven panels, which show the patches observed along Ganymede’s
aurora smoothed using a 3 ×3 Gaussian kernel with 2 sigma that approximately matches the∼0.1◦ point spread function of UVS. We encircled
the visually identified patches. The color levels are logarithmic; for panels a-g, we visually display 100R (S/N∼1) as the lower level to highlight
the beads. — Fig. 1. Top-left panel: Projection of Ganymede’s FUV aurora acquired by Juno-UVS on June 7th, 2021, from 16:52 to 17:04 UTC.

Last night I set up my telescope so we could all watch the planets while waiting for the new year to arrive.

After the fireworks had subsided, I attached my camera and captured my first astrophoto of the year featuring Jupiter and its moon Europa.

Happy New Year everyone!

The planet Jupiter with its many bands of clouds spanning around it. The Great Red Spot is visible on the right side of the planet, about to rotate out of view. To the left of the planet is a bright dot, which is the moon Europa.

GEMINIDS PEAK THIS WEEKEND

The best meteor shower of 2025 peaks Dec 12–13 and 13–14 as Earth passes through debris from rock-comet 3200 Phaethon. Real talk: it’s not a downpour—expect 1–2 meteors per minute if you’re patient. Spend 30 minutes under dark skies between 10 pm–2 am and you’ll likely catch bright streaks or a fireball. Bonus: Jupiter joins the show. More info: https://spaceweather.com/

The image is divided into four sections, each showing one of the gas giants against a black background as seen by JWST. Filters are near infrared and have been colorised.

Top left: Jupiter. It appears as a large, round sphere with horizontal bands in shades of light brown, tan, and white. A bright white oval storm sits on the lower right side. A faint ring is visible alongside Europa, one of its satellites, which appears very bright with a star-shaped artifact.

Top right: Saturn. It has a pale beige surface with soft horizontal shading. Surrounding it is a wide, bright ring system tilted diagonally. The rings look thin and sharply defined, with multiple subtle bands of light and dark.

Bottom left: Uranus. It appears as a smooth blue-green sphere with some whitish circular clouds around the pole that is facing the observer. Surrounding it is a bright circular ring system made up of thin white lines. The rings form a bright, symmetrical halo around the planet.

Bottom right: Neptune. It is a blue sphere with slightly brighter and darker circular features on its atmosphere. It also has a thin ring system, dimmer and less defined than Uranus’s in this image, appearing as a faint double oval around the planet.

Each planet has its name printed below it in white capital letters. — The image is divided into four sections, each showing one of the gas giants against a black background as seen by JWST.

[ #Waves and #Plasma] Numerous #moons orbit #Jupiter, including #Io, whose volcanic activity causes the ejection of #matter and the formation of a magnetized #plasma disc—or #magnetodisc—in the equatorial plane of the gas giant.

How does the plasma in this magnetodisk manage to remain in a state of #equilibrium? By emitting waves, according to a new study based on data acquired by the #Juno probe, which has been orbiting #Jupiter since 2016.

This illustration also includes Jupiter, Io, Io’s torus (orange zone surrounding Io), Jupiter’s ionosphere (green zone surrounding Jupiter), magnetic field lines (black curves), and Juno’s trajectory relative to the magnetodisk.
