Saturn’s rings reveal a fuzzy, sloshy core lurks within the planet

NASA’s dearly-departed Cassini spacecraft helps scientists study Saturn’s insides.

We can’t send a spacecraft into the belly of the gas giant planet Saturn (well, at least, not one that survives), so sorting out what’s going on in there requires some clever science work. By examining Saturn’s famous rings, a team of researchers has made new discoveries about the planet’s interior.

Some theories suggested Saturn’s core might be a ball of rock, but a study published in the journal Nature Astronomy this week reveals what’s likely «a diffuse soup of ice, rock, and metallic fluids» called a «fuzzy» core.

«The analysis also reveals that the core extends across 60% of the planet’s diameter, which makes it substantially larger than previously estimated,» the California Institute of Technology said in a statement on Monday.

The researchers used data from NASA’s dearly departed, Saturn-studying spacecraft Cassini to make the discoveries. The team focused on ripples in the rings that are caused by a jiggling of the planet’s interior. Caltech likened this concept to that of earthquakes causing our own planet to rumble.

Astronomers have been aware for decades of how Saturn’s jiggling might affect its rings, and the new study brings this idea into sharper focus. «We used Saturn’s rings like a giant seismograph to measure oscillations inside the planet,» said Caltech astrophysicist Jim Fuller, a co-author. «This is the first time we’ve been able to seismically probe the structure of a gas giant planet, and the results were pretty surprising.»

Saturn might have a sloshy belly, but the team thinks it has stable layers with heavier materials in the middle. «The fuzzy cores are like a sludge. The hydrogen and helium gas in the planet gradually mix with more and more ice and rock as you move toward the planet’s center,» said lead author and planetary scientist Christopher Mankovich.

The Saturn findings could help us understand more about what’s going on inside Jupiter, also a gas giant planet. It could also advance ideas about how gas giants form.

NASA’s Cassini spacecraft plunged to its destruction in 2017 at the end of its mission, but it left us with many years worth of data on Saturn, its rings and its moons. As this new study shows, it wasn’t all about the gorgeous exterior views. Cassini’s journey has reached all the way to the very center of the planet.

TAPE, COIN, PENCIL, BATTERY, SHOELACE, THUMBTACK

Today’s Strands spangram is JUNKDRAWER. To find it, look for the J that’s five letters down on the far-left row, and wind down, over and then up.

#1: To get more clue words, see if you can tweak the words you’ve already found, by adding an «S» or other variants. And if you find a word like WILL, see if other letters are close enough to help you make SILL, or BILL.

#2: Once you get one theme word, look at the puzzle to see if you can spot other related words.

#3: If you’ve been given the letters for a theme word, but can’t figure it out, guess three more clue words, and the puzzle will light up each letter in order, revealing the word.
