Christiaan Huygens, Lord of Zeelhem, FRS (/ ˈ h aɪ ɡ ən z / HY-gənz, [2] US also / ˈ h ɔɪ ɡ ən z / HOY-gənz; [3] Dutch: [ˈkrɪstijaːn ˈɦœyɣə(n)s] ⓘ; also spelled Huyghens; Latin: Hugenius; 14 April 1629 – 8 July 1695) was a Dutch mathematician, physicist, engineer, astronomer, and inventor who is regarded as a key figure in the Scientific Revolution.
The enormous crater Herschel on Saturn's moon Mimas; The Herschel gap in Saturn's rings. 2000 Herschel, an asteroid; The William Herschel Telescope on La Palma; The Herschel Space Observatory, successfully launched by the European Space Agency on 14 May 2009. It was the largest space telescope of its kind, until the launch of the James Webb ...
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 ...
Mark Robert Showalter (born December 5, 1957) is a senior research scientist at the SETI Institute. [1] He is the discoverer of six moons and three planetary rings. He is the Principal Investigator of NASA's Planetary Data System Rings Node, a co-investigator on the Cassini–Huygens mission to Saturn, and works closely with the New Horizons mission to Pluto.
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.
Famously known for its extensive ring system, Saturn is one of four planets in our solar system that have the distinctive feature. And now, scientists hypothesize that Earth may have sported its ...
Cassini was born in Perinaldo, [2] [3] near Imperia, at that time in the County of Nice, part of the Savoyard state. [4] [5] He discovered four satellites of Saturn and noted the division of its rings, later named the Cassini Division. Cassini was also the first of his family to begin work on the project of creating a topographic map of France ...
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.
