One of the fundamental tenets of physics is that two objects, now matter how different their size, exert a force on each other. In most cases the size makes a big difference, with the larger objects enacting a much greater force on the smaller one.
However, over long periods of time, even much smaller objects can have an effect on the larger object in the pair. Recently a team of researchers from CNRS, the Sorbonne, and the University of Pisa have found an example of the smaller object, or in this case group of objects, having an outsized impact on the larger one. They have discovered that Saturn’s moons actually caused its famous tilt.

Using the Atacama Large Millimeter/submillimeter Array (ALMA), a team of scientists has identified a mysterious molecule in Titan’s atmosphere. It’s called cyclopropenylidene (C3H2), a simple carbon-based compound that has never been seen in an atmosphere before. According to the team’s study published in The Astronomical Journal, this molecule could be a precursor to more complex compounds that could indicate possible life on Titan.
Similarly, Dr. Catherine Neish of the University of Western Ontario’s Institute for Earth and Space Exploration (Western Space) and her colleagues in the European Space Agency (ESA) found that Titan has other chemicals that could be the ingredients for exotic life forms. In their study, which appeared in Astronomy & Astrophysics, they present Cassini mission data that revealed the composition of impact craters on Titan’s surface.

A new study of the mysterious hexagon-shaped storm at Saturn’s north pole suggests this phenomenon is actually the result of activity occurring across the entire planet.

If you want an iconic picture of the planet Saturn, it doesn’t get any better than this. The latest picture from the Hubble Space Telescope shows a spectacular view of the ringed giant, taken on July 4, 2020. This shows a “summertime” view of Saturn’s northern hemisphere.

Where did Saturn’s bizarro-moon Titan form? Did it form where it is now, or has it migrated? We have decades of data to look back on, so scientists should have some idea.
A new study based on all that data says that Titan is drifting away from Saturn more quickly than thought, and that has implications for where the moon initially formed.

The reign of Jupiter, named after the father of the Olympian gods, has been long and sweet. Aside from being the largest planet in the Solar System, it was this gas giant that demonstrated in the 17th century that planets other than Earth can support a system of moons. Between its size, powerful magnetic field, and system of 79 moons, Jupiter looked set to remain the king of the planets indefinitely.
But it looks like Saturn, named after the father of Jupiter in Greco-Roman mythology, might have just knocked Jupiter off that pedestal. Thanks to a team led by famed astronomer Scott S. Sheppard 20 new moons have been discovered orbiting Saturn. That brings the total number of Saturnian (or Cronian) satellites to 82, putting it ahead of Jupiter’s 79. And the best part? You can help name them!

Radar evidence shows that geysers on Enceladus are ejecting water that turns to snow. The snow not only falls back on Enceladus’ surface, but also makes its way to its neighboring moons, Mimas and Tethys, making them more reflective. Researchers are calling this a ‘snow cannon.’

Hubble has captured a new image of Saturn that makes you wonder if it’s even real. The image is so crisp it makes it look like Saturn is just floating in space. Which it is.

For a rocky planet, finding the length of a day can be simple. Just pick a reference point and watch how long it takes to rotate out of view, then back into view. But for planets like Saturn, it’s not so simple. There are no surface features to track.

The Cassini mission to Saturn ended a year and a half ago, but scientific results are still coming from all of the data it collected. When Cassini moved in closer to Saturn in its final months, it took a very detailed look at the gas giant’s rings, travelling between them and the planet itself. That detailed inspection raised quite a few questions about all the interactions shaping those rings.
A new paper published in Science presents some of the results from Cassini’s close-up look at the rings.
