Encyclopedia
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine and a half times that of Earth. It has only one-eighth the average density of Earth; however, with its larger volume, Saturn is over 95 times more massive. Saturn’s interior is most likely composed of a core of iron–nickel and rock (silicon and oxygen compounds). Its core is surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium, and finally, a gaseous outer layer. The planet’s most notable feature is its prominent ring system, which is composed mainly of ice particles, with a smaller amount of rocky debris and dust. — Wikipedia

Solar System Treks are online, browser-based portals that allow you to visualize, explore, and analyze the surfaces of other worlds using real data returned from a growing fleet of spacecraft. You can view the worlds through the eyes of many different instruments, pilot real-time 3D flyovers above mountains and into craters, and conduct measurements of surface features. These Solar System Treks showcase data about the moons of Saturn collected by the Cassini spacecraft which was launched in 1997. — Titan Trek (Solar System Treks, NASA)

Innovation
Science
NASA and Durham University simulations put forth a theory of the origin of Saturn’s rings and icy moons – they may have formed following a massive collision between two moons orbiting the gas giant. The simulations used in this research are some of the most detailed of their kind to study the formation of Saturn’s rings and potentially habitable icy moons. — NASA’s Ames Research Center

History
The observation and exploration of Saturn can be divided into three phases: (1) pre-modern observations with the naked eye, (2) telescopic observations from Earth beginning in the 17th century, and (3) visitation by space probes, in orbit or on flyby. In the 21st century, telescopic observations continue from Earth (including Earth-orbiting observatories like the Hubble Space Telescope) and, until its 2017 retirement, from the Cassini orbiter around Saturn. — Wikipedia

Pioneer programs were two series of United States lunar and planetary space probes exploration. The second program, which ran from 1965 to 1992, sent four spacecraft to measure interplanetary space weather, two to explore Jupiter and Saturn, and two to explore Venus. The two outer planet probes, Pioneer 10 and Pioneer 11, became the first of five artificial objects to achieve the escape velocity that will allow them to leave the Solar System. — Wikipedia

Voyager Program is an American scientific program that employs two robotic interstellar probes, Voyager 1 and Voyager 2. They were launched in 1977 to take advantage of a favorable alignment of Jupiter and Saturn, to fly near them while collecting data for transmission back to Earth. After launch the decision was taken to send Voyager 2 near Uranus and Neptune. — Wikipedia

Cassini–Huygens Mission was a collaboration among NASA, the European Space Agency (ESA), and the Italian Space Agency (ASI) to send a space probe to study the planet Saturn and its system, including its rings and natural satellites. The Flagship-class robotic spacecraft comprised both NASA’s Cassini space probe and ESA’s Huygens lander, which landed on Saturn’s largest moon, Titan. Cassini was launched on October 15, 1997, and it entered Saturn’s orbit on July 1, 2004. The mission ended on September 15, 2017, when Cassini’s trajectory took it into Saturn’s upper atmosphere and it burned up. — Wikipedia

If you've ever taken an introductory astronomy class, you've probably seen the Hertzsprung-Russell (HR) diagram. This graph maps out the life cycle of stars by plotting their temperature against their luminosity, and has been a "cheat sheet" for stellar astrophysics for over a century. But the universe is full of more than just stars, and a new paper in the journal Publications of the Astronomical Society of the Pacific by Gabriel Steward and Matthew Hedman of the University of Idaho, attempts […]
- Hubble survey sets up Roman's future look near...on May 11, 2026 at 7:20 pm
The Milky Way's galactic bulge, the bulbous region that surrounds the galactic center, contains a dense collection of stars, planets, and other free-floating objects. This region has been studied for decades with numerous ground-based and space-based telescopes, including NASA's Hubble and James Webb space telescopes.
- Saturn's icy rings likely formed from lost moon...on May 11, 2026 at 6:40 pm
You're a long-necked Titanosaur grazing the plains and chomping away on tree leaves about 100 million years ago in the Early Cretaceous in what would eventually become a future Starbucks location. You look up at the night sky and notice a bright dot that seems slightly larger and brighter than usual since you've seen it a bunch. You grunt at your cousin (official dinosaur language) asking if he notices it, too. Your cousin grunts back that it does seem bigger and brighter and wonders what's up.
- Close-in planets act as 'bouncers' to create...on May 4, 2026 at 12:40 pm
Rogue planets sound like rare travelers among the stars, freed from the gravitational constraints of a host system, left to forever wander the interstellar void. But modern models suggest these free floating planets (FFPs) as they are technically known, are actually very common—19 times more common than planets beyond the "snow line," which is the distance from the central star where it becomes cold enough that hydrogen compounds like water, ammonia, and methane can condense into ice.

NASA's Curiosity Mars rover has uncovered a diverse mix of organic molecules on Mars, including chemicals widely considered building blocks for the origin of life on Earth.
