The main rings are, working outward from the planet, C, B and A, with the Cassini Division, the largest gap, separating Rings B and A. Several fainter rings were discovered more recently. The D Ring is exceedingly faint and closest to the planet. The narrow F Ring is just outside the A Ring. Beyond that are two far fainter rings named G and E.
Saturn's rings are the most extensive ring system of any planet in the Solar System, and thus have been known to exist for quite some time. Galileo Galilei first observed them in 1610, but they were not accurately described as a disk around Saturn until Christiaan Huygens did so in 1655. [ 15 ]
Cassini–Huygens (/ kəˈsiːniˈhɔɪɡənz / kə-SEE-nee HOY-gənz), commonly called Cassini, was a space-research mission by 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 ...
27 February 2004 – A new, high-resolution picture of Saturn taken by Cassini on 9 February was released, and it was noted that mission scientists were puzzled by the fact that no "spokes" in Saturn's ring are visible. These dark structures in the "B" section of the ring had been discovered in pictures taken by the Voyager probe in 1981. [17]
The moonlet was first discovered in 2013, although its discovery was possible in 2012. [4] Cassini took 2 images of the edge of Saturn's A Ring, thereby ruling out it being a cosmic ray artifact. [3] There were disturbances at the edges of Saturn's A Ring, with one of these being approximately 20% brighter than its surroundings. There were also ...
Astronomers have noticed unusual movement in Saturn's rings. Here's the discovery in layman's terms: Generally, the ice and rocks that make up the rings travel outwards because of the ...
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]
September 18, 2024 at 1:43 AM. Earth may briefly have had a ring system similar to Saturn ’s over 450 million years ago during a period of unusually intense meteorite bombardment, a new study ...
