Jupiter is the largest known planet in the entire solar system, and planetary scientists have been debating about how it formed for as long as we can remember. But new research published this week in ...

Scientists have measured that Jupiter releases more internal heat than it absorbs from the Sun, based on observations of its structure, rotation, and atmospheric behavior.

When compared to the outermost planets in our solar system, the four planets closest to the sun — Mercury, Venus, Earth and Mars — are quite small. Astronomers believe this is because a massive planet ...

New calculations reported by Live Science indicate Jupiter was once much larger and is still contracting as it cools, offering constraints on early solar system conditions.

What processes were responsible for Jupiter’s formation? This is what a recent study published in Scientific Reports hopes to address as an international pair of scientists investigated the physical, ...

Scientists studying data from NASA's Galileo spacecraft have found that Jupiter's moon Amalthea is a pile of icy rubble less dense than water. Scientists expected moons closer to the planet to be ...

Over the last two decades, the discovery of thousands of exoplanets outside our solar system has shaken up old theories about how planets form;the recent discovery of an "infant Jupiter," rich in ...
