Cosmic noise, also known as galactic radio noise, is a physical phenomenon derived from outside of the Earth's atmosphere. It is not actually sound, and it can be detected through a radio receiver , which is an electronic device that receives radio waves and converts the information given by them to an audible form.
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.
Upsweep is an unidentified sound detected on the American NOAA's equatorial autonomous hydrophone arrays. This sound was present when the Pacific Marine Environmental Laboratory began recording its sound surveillance system, SOSUS, in August 1991.
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.
The Great White Spot, also known as Great White Oval (named by analogy to Jupiter's Great Red Spot) is a series of periodic storms on the planet Saturn that are large enough to be visible from Earth by telescope by their characteristic white appearance.
It acquires its energy in the deep layers of Saturn's atmosphere and produces radio waves that reflect during its burst of short static which helped Cassini detect it. The Dragon Storm (named in September 2004 for its unusual shape) is a large, bright and complex convective storm in Saturn's southern hemisphere. It appears to be long-lived and ...
The extended distance corresponds to Rhea's Hill sphere, the distance of 7.7 times Rhea's radius inside of which orbits are dominated by Rhea's rather than Saturn's gravity. When Cassini emerged from Rhea's plasma shadow, the reverse pattern occurred: A sharp surge in energetic electrons, then a gradual increase out to Rhea's Hill-sphere radius.
Saturn is named after the Roman god of wealth and agriculture, who was the father of the god Jupiter.Its astronomical symbol has been traced back to the Greek Oxyrhynchus Papyri, where it can be seen to be a Greek kappa-rho ligature with a horizontal stroke, as an abbreviation for Κρονος (), the Greek name for the planet ().
