Saturn's radiation belts. Saturn has relatively weak radiation belts, because energetic particles are absorbed by the moons and particulate material orbiting the planet. [47] The densest (main) radiation belt lies between the inner edge of the Enceladus gas torus at 3.5 R s and the outer edge of the A Ring at 2.3 R s.
Saturn Electrostatic Discharges (also referred to as SEDs) are atmospheric lightning events in convective weather storms on Saturn that produce high frequency (HF) radio emissions (1–40 MHz). Terrestrial lighting events on Earth , in comparison, occur in the very low frequency (VLF) radio band, between 3 Hz and 30 kHz.
The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band. From low to high frequency these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and ...

NASA's Cassini spacecraft, which explored Saturn and its icy moons, including the majestic Titan, ended its mission with a death plunge into the giant ringed planet in 2017. Cassini's radar ...
Saturn's atmosphere exhibits a banded pattern similar to Jupiter's, but Saturn's bands are much fainter and are much wider near the equator. The nomenclature used to describe these bands is the same as on Jupiter. Saturn's finer cloud patterns were not observed until the flybys of the Voyager spacecraft during the 1980s.
The unusual image was taken by a camera on the Cassini spacecraft on April 8, 2016, at a distance of about 1.4 million miles away from Saturn. NASA spots mysterious activity in Saturn's F Ring ...
Because intensity mapping surveys can be carried out much faster than conventional optical redshift surveys, it is possible to map-out significantly larger volumes of the Universe. As such, intensity mapping has been proposed as a way of measuring phenomena on extremely large scales, including primordial non-Gaussianity from inflation [ 11 ...
