Saturn has a hot interior, reaching 11,700 °C (21,100 °F) at its core, and radiates 2.5 times more energy into space than it receives from the Sun. Jupiter's thermal energy is generated by the Kelvin–Helmholtz mechanism of slow gravitational compression; but such a process alone may not be sufficient to explain heat production for Saturn ...
The second hypothesis is that the rings were never part of a moon, but are instead left over from the original nebular material from which Saturn formed. [citation needed] A 2007 artist's impression of the aggregates of icy particles that form the 'solid' portions of Saturn's rings. These elongated clumps are continually forming and dispersing.
2013 and 2017: hexagon color changes. Between 2012 and 2016, the hexagon changed from a mostly blue color to more of a golden color. [21] One hypothesis for this is that sunlight is creating haze as the pole is exposed to sunlight due to the change in season. These changes were observed by the Cassini spacecraft. [21]
Ring particles modifying Saturn’s upper atmosphere, changing its composition, scientists say Saturn’s rings are breaking apart and heating up planet’s thin atmosphere, study finds Skip to ...
For half of Saturn's "year," the planet is tilted toward the sun, lighting the top of its rings. And, for the other half of its year, the reverse is true. The planet's axis tilts away from the sun ...
Artist's conception of the giant impact thought to have formed the Moon. Jupiter and Saturn have several large moons, such as Io, Europa, Ganymede and Titan, which may have originated from discs around each giant planet in much the same way that the planets formed from the disc around the Sun. [88] [89] [90] This origin is indicated by the ...
The ring would have formed along the equator due to Earth’s equatorial bulge, similar to how the rings of Saturn, Jupiter, Uranus and Neptune are also around each of those planets’ equatorial ...
[18] [36] Its faint apparent magnitude (H V = +11.7) and its proximity to the much brighter Saturn and Saturn's rings make Enceladus difficult to observe from Earth with smaller telescopes. Like many satellites of Saturn discovered prior to the Space Age , Enceladus was first observed during a Saturnian equinox, when Earth is within the ring plane.
