A Cosmic Collision: Titan and a Lost Moon May Have Forged Saturn's Rings

Scientists combining Titan formation ideas, Cassini data, and simulations propose that Titan collided with a lost proto-moon about 500 million years ago; the wreckage may have become Hyperion and also helped forge Saturn’s rings, while Titan’s altered mass could have nudged Saturn’s tilt and resonance with Neptune. Titan’s orbit is expanding, and NASA’s Dragonfly mission to Titan (launch 2028, arrival 2034) could test this scenario.

Titan Collision May Have Scuplted Saturn’s Rings and Tilt

Space.com reports Matija Ćuk and colleagues propose Saturn’s Titan may have formed from a collision/merger with a now-missing moon called Chrysalis about 100–200 million years ago. This upheaval could have widened Titan’s orbit, triggered further moon collisions, redistributed Saturn’s mass to alter its precession, and helped form Saturn’s rings. Hyperion might be a debris remnant from the event. Cassini data revised Saturn’s internal mass distribution, moving it slightly out of Neptune’s orbital resonance. There’s no direct evidence yet, but the scenario is being explored in Planetary Science Journal with an arXiv preprint, and future Dragonfly observations could test it.

Planetary parade in February: Jupiter dominates the night sky as Mercury makes its best evening appearance

February 2026 offers one of the year’s best planetary lineups: Jupiter shines high in the eastern sky after sunset, Mercury appears for a three‑week window low in the west‑southwest starting Feb. 6, Venus becomes more visible toward month’s end, Mars remains hidden near the Sun, and Saturn sinks lower in the sky; the piece provides viewing tips and timing, including Mercury’s Feb. 18–19 Crescent Moon pairing and its greatest elongation around Feb. 19.

Deep Interior Coupling May Shape Jupiter and Saturn’s Polar Storms

MIT researchers show that Jupiter’s multiple polar vortices and Saturn’s single polar storm stem from how strongly storms are coupled to deeper interior layers. A 2D fluid-dynamics model suggests Jupiter’s weaker layering and stronger atmospheric forcing keep many discrete storms from merging, while Saturn’s deeper layering and greater energy loss allow vortices to merge into one giant storm. These surface patterns may encode information about each planet’s interior properties and formation history.

January's new moon clears the sky for prime Jupiter and Saturn viewing

January 18, 2026’s new moon will yield dark skies ideal for skywatchers: Jupiter and Saturn will dominate the January night, with Jupiter rising around 4 p.m. and visible for hours in the east, and Saturn high in the southwest after sunset in the Northern Hemisphere; Mercury, Venus and Mars remain too close to the Sun to see that month. In the Southern Hemisphere, the inverted sky highlights southern constellations with Jupiter as a reference point. The article also offers tips for spotting bright stars and constellations like Orion, Sirius, Aldebaran, the Pleiades and the Hyades, and notes that deep-sky observing is best away from light pollution during a new moon.

Tips for Viewing Saturn and Jupiter with a Telescope

To see Saturn and Jupiter clearly through a telescope, a refractor with at least 50mm aperture is recommended, with larger apertures like 102mm or 125mm providing more detail such as Saturn's rings and Jupiter's Great Red Spot. For higher detail, pricier catadioptric telescopes are ideal. Viewing Uranus and Neptune requires even larger telescopes, around 200mm, and a motorized mount can help locate these distant planets.
