What lurks beneath the volcanoes of Jupiter’s moon Io? NASA’s Juno probe just took a peek

The subsurface findings could transform how scientists study volcanoes across the solar system — including those on Earth.

The first possible exomoon is here, and it makes our Moon look hilariously tiny

Astronomers have found strong evidence for a Jupiter-mass object orbiting a brown dwarf, potentially marking the first convincing detection of a moon beyond our solar system.

NASA’s Juno Takes Temperature of Jupiter’s Fiery Moon Io
NASA’s Juno Takes Temperature of Jupiter’s Fiery Moon Io

 NASA’s Juno mission has provided the first measurements of the temperature below the surface of Jupiter’s moon Io, revealing significant heating within the shallow subsurface of the most volcanically active world in the solar system. Collected during two close flybys, the data also shows that most of Io’s surface is remarkably smooth and composed of […]

Moon joy at Jupiter | Space photo of the day for May 7, 2026

NASA’s Juno spacecraft captured a photo of Jupiter’s moon Thebe.

Lightning on Jupiter could be up to 1 million times stronger than on Earth

Lightning on Jupiter may pack more than 100 times the power of Earth’s bolts, and may prove one million times stronger, a new study finds.

Jupiter’s moons leave cold ‘footprints’ in the planet’s auroras, James Webb Space Telescope finds

Never-before-seen temperature and ion density measurements reveal that the effect of Jupiter’s moons on its aurora are more complicated than scientists thought.

Auroras on Jupiter’s giant moon Ganymede look like Earth’s northern lights, NASA spacecraft reveals

Ganymede’s auroras splinter into small, bright patches — structures that mirror features seen in Earth’s own auroral displays.

Listen to This Month’s ‘Planetary Parade’ With NASA’s Chandra

In late February, people in the Northern Hemisphere can look up for a special sight : Six planets will all be visible from clear and dark night skies. New sonifications from NASA’s Chandra X-ray Observatory released [day of week] will help commemorate this latest “planetary parade.” Because the planets in our solar system travel around […]

Is Jupiter on a diet? New measurements say it’s smaller than we thought

Jupiter may be a bit more petite than expected, and that could have a big impact on how scientists model the mysterious interior of the giant planet.

NASA’s Juno spacecraft spots the largest volcanic eruption ever seen on Jupiter’s moon Io

“What makes the event even more extraordinary is that it did not involve a single volcano, but multiple active sources.”
