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 water ice is delivered by powerful convections originating from about 200 km deep in Saturn's atmosphere. [14] The 2010 GWS also had an increased level of lightning. It had 10 Saturn Electrostatic Discharges (SED) per second, while synoptic-scale storms on Saturn had a few SEDs per seconds. [5]
Saturn's Great White Spot, imaged by NASA's Cassini Spacecraft in 2011 False color image of the Dragon Storm, imaged by Cassini. Every Saturn year, about 28 Earth years, Saturn has massive planet-circling storms, called Great White Spots. The Great White Spots are short-lived but can impact the atmosphere and temperature of the planet for up to ...
On Sunday, Aug. 27, Saturn will reach opposition, the point in its orbit when it appears in the opposite part of the sky as the sun. As a result, the planet will shine all night long, rising in ...
Titan’s surface has a temperature of minus 290 degrees, experts say.
However, one planet stands out from the rest, at least in appearance, having an elaborate system of breathtaking rings: Saturn. August is the best time in 2022 to view the ringed planet in the ...
[4] [5] [10] It rotates with a period of 10h 39m 24s, the same period as Saturn's radio emissions from its interior. [11] The hexagon does not shift in longitude like other clouds in the visible atmosphere. [12] Saturn's hexagon was discovered during the Voyager mission in 1981, and was later revisited by Cassini-Huygens in 2006.
Fox Weather 3 hours ago Prolonged polar vortex has much of US preparing for life-threatening cold, pipe-bursting temperatures. A dangerous and potentially life-threatening stretch of cold weather has much of the U.S. on alert as a lobe of the polar vortex invades the nation and sends temperatures tumbl…
