“We try to measure the notes Saturn plays, and then use that to figure out what’s inside the planet,” Fuller says. Sometimes that means requisitioning the blueprints for an unexpected instrumen ...

By observing waves in Saturn's rings, scientists were able to measure the size and shape of the planet's core—and it's much larger and more bizarre than anyone could have guessed. Hidden inside ...

The type of oscillation that Mankovich and Fuller detect inside Saturn also implies that the core is stable rather than bubbling like a pot of water on a hot stove, which is one way a planet can ...

Right now, measuring those oscillations offers scientists the best possible chance to grasp what's going on far inside the planet, like Saturn's internal rotation or structure, which appears to be ...

NASA’s Cassini spacecraft dove inside Saturn’s rings for the first time on April 26, its first of 22 planned orbits close to the planet’s atmosphere. Cassini returned the closest images ever ...

Despite the surface seeing a chilly minus 330 degrees Fahrenheit, Enceladus’ interior luxuriates at around 200 degrees Fahrenheit, thanks to tidal heating from Saturn. The mother planet’s ...

Meanwhile, the loss of the moon would also change the gravitational pulls acting on Saturn, altering the planet’s moment of inertia, or how mass is distributed inside the planet. "It is exciting ...

But later this month, the two largest planets in the solar system will ... If Jupiter is running in circles closer to the inside, Saturn is walking at a slower pace farther out.

That’s as close as you can get to a measure for the length of a “day” on a gas giant planet. Combining the gravitational data with models of Saturn’s interior also allowed the researchers ...

With planets and moons, it’s what’s inside that counts. If we want to understand surface ... Astronomer Sabine Stanley takes us on a journey to the centers of Venus, Saturn’s large moon Titan, Jupiter ...
