Porco was the first person to describe the behavior of the eccentric ringlets and the "spokes" discovered by Voyager within the rings of Saturn; to elucidate the mechanism by which the outer Uranian rings were being shepherded by the Voyager-discovered moons Cordelia and Ophelia; and to provide an explanation for the shepherding of the rings ...
Cassini was born in Perinaldo, [2] [3] near Imperia, at that time in the County of Nice, part of the Savoyard state. [4] [5] Cassini is known for his work on astronomy and engineering. He discovered four satellites of Saturn and noted the division of its rings; the Cassini Division was named after him.
He discovered Saturn's biggest moon, Titan, and was the first to explain Saturn's strange appearance as due to "a thin, flat ring, nowhere touching, and inclined to the ecliptic." [10] In 1662 Huygens developed what is now called the Huygenian eyepiece, a telescope with two lenses to diminish the amount of dispersion. [11]
The latter include the D Ring, extending inward to Saturn's cloud tops, the G and E Rings and others beyond the main ring system. These diffuse rings are characterised as "dusty" because of the small size of their particles (often about a μm); their chemical composition is, like the main rings, almost entirely water ice. The narrow F Ring ...
Giovanni Domenico Cassini, discoverer of Iapetus. Iapetus was discovered by Giovanni Domenico Cassini, an Italian-born French astronomer, in October 1671.This is the first moon that Cassini discovered; the second moon of Saturn to be discovered after Christaan Huygens spotted Titan 16 years prior in 1655; and the sixth extraterrestrial moon to be discovered in human history.
A study published in the journal Science suggests a hypothetical moon (called Chrysalis) came too close to Saturn's gravitational pull and was torn apart, forming the planet's iconic rings.
Christiaan Huygens followed on from Galileo's discoveries by discovering Saturn's moon Titan and the shape of the rings of Saturn. [14] Giovanni Domenico Cassini later discovered four more moons of Saturn and the Cassini division in Saturn's rings. [15] The Sun photographed through a telescope with special solar filter.
Saturn’s autumnal equinox is expected to occur on May 6, 2025. Spying Saturn’s spokes The NASA Voyager 2 spacecraft captured the first evidence of the spokes in the 1980s.
