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.

Using the Webb telescope, scientists discovered an unexpectedly cold, dense region within Io’s auroral footprint in Jupiter’s northern lights.

Exomoons orbiting rogue planets could host liquid water for billions of years, offering potential habitats for life deep in interstellar space.

New research suggests that Jupiter’s icy moons may have formed with complex organic molecules already embedded in their building blocks.

Turn a telescope to the eastern sky in the hours following midnight on Nov. 5 to see two colossal shadows darken the cloud tops of the gas giant Jupiter as the Galilean moons Io and Europa pass ...

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

When did Jupiter’s Galilean moons first contain the ingredients for life? This is what complementary studies published in The Planetary Science Journal and Monthly Notices of the Royal Astronomical ...

A comet from another star system will swing by Mars on Friday as a fleet of spacecraft trains its sights on the interstellar visitor. We already know a decent amount about how planets form, but moon ...

There’s no mistaking Jupiter in the sky these Pottsville winter evenings, rising in the southeast as evening twilight ends. In fact you should be able to easily see it long before twilight fades.

Jupiter’s icy moons may have been seeded with the chemical ingredients for life from the very beginning. An international team of scientists modeled how complex organic molecules—essential building ...
