Saturn
Saturn is the 2nd largest planet of our Solar System and the only one adorned with a ring system easily seen by even modest telescopes. While the Cassini spacecraft helped unlock many of Saturn's secrets, our goal is to continue to observe and record the subtle changes that take place on this dynamic planet to further our knowledge about it.

Saturn Spoke Season
7/31/2026

We recently received an amazing animation from ALPO member Anthony Wesley from Rubyvale, Queensland, AU. The spokes clearly appear as faint, roughly radial dark streaks crossing the B-ring. In this near-infrared sequence they remain visible for nearly two hours as Saturn rotates, standing out against the brighter ring material.

Details
• Observation: 21 July 2026, 18:42.9 – 20:30.8 UTC
• 28-frame animation
• Filter: 685 nm long-pass (Deep red)
• Scope: 415 mm f/4 Newtonian + Baader FFC + eADC

Spokes are transient, electrically charged dust features first imaged by Voyager in 1980. Fine ice particles are lifted slightly above the ring plane by electrostatic forces, often triggered by micrometeoroid impacts or interactions with Saturn’s magnetic field and plasma environment. Because the particles are small, their appearance depends strongly on lighting and viewing geometry: they usually look dark in backscattered light (as here) and brighter when seen in forward scatter. They are most frequent and conspicuous near Saturn’s equinoxes, when the Sun is low over the rings, but can still be recorded at other seasons under good conditions.

Our sincere thanks (and congratulations!) to Anthony for sharing his work with the ALPO. You can see more of his images in the current Saturn apparition gallery.


2026 Saturn Apparition
3/14/2026

In 2026, Saturn reaches opposition on October 4, offering its best viewing, brightest (magnitude 0.3), and closest distance of 784 million miles. The rings will appear nearly edge-on—only a 7° inclination. 

Key 2026 Saturn Highlights:

  • Visibility:Saturn will be in the evening sky through early March, disappear near the Sun in late March, then move to the morning sky before returning to the evening for its October 4 opposition, 
  • Appearance:Due to the near-edge-on view of the rings, the ringed planet will appear as a thin line across the planet.
  • Conjunctions:
    • March 8:Venus and Saturn conjunction.
    • April 20:Alignment with Mars and Mercury.
  • Constellation:Saturn will reside in the constellations Pisces and Cetus throughout the year,

New Study Assesses Titan's Resources and Their Potential Uses
6/22/2026

TBD
A NASA-supported study highlights Saturn's largest moon, Titan, as a premier candidate for future human exploration and settlement. Thanks to its dense nitrogen atmosphere and abundant liquid methane and water-ice, Titan offers unrivaled opportunities for in-situ resource utilization. Researchers suggest that establishing outposts there could transform the Cronian system into a primary refueling and supply base for deeper missions heading toward Uranus, Neptune, or the outer solar system.

Astronomers Keep Finding New Moons of Jupiter and Saturn
3/27/2026

TBD
The Minor Planet Center has officially announced the discovery of four new moons for Jupiter and eleven for Saturn, bringing their respective totals to 101 and 285. These tiny satellites, averaging only two miles in diameter, were identified using high-powered telescopes in Chile and Hawaii. This haul brings the total known planetary moons in our solar system to 442, highlighting the complex gravitational environments surrounding our local gas giants.

Webb & Hubble Capture New Views of Saturn
3/27/2026

TBD
A rare "telescope team-up" has provided a comprehensive look at Saturn’s atmosphere. While Hubble captured subtle color variations in visible light, the James Webb Space Telescope used infrared sensors to peer through deep cloud layers and detect chemical compositions at varying depths. These observations represent the last high-resolution look at Saturn's famous northern hexagon before the pole enters a 15-year period of winter darkness.
