A rendering of the magnetic field lines of the magnetosphere of the Earth. In astronomy and planetary science, a magnetosphere is a region of space surrounding an astronomical object in which charged particles are affected by that object's magnetic field. [1] [2] It is created by a celestial body with an active interior dynamo.
The magnetosphere is defined by the extent of Earth's magnetic field in space or geospace. It extends above the ionosphere , several tens of thousands of kilometres into space , protecting Earth from the charged particles of the solar wind and cosmic rays that would otherwise strip away the upper atmosphere, including the ozone layer that ...
α - RA, right ascension, if the Greek letter does not appear, á letter will appear. δ - Dec, declination, if the Greek letter does not appear, ä letter will appear. P or P orb or T - orbital period; a - semi-major axis; b - semi-minor axis; q - periapsis, the minimum distance; Q - apoapsis, the maximum distance; e - eccentricity; i ...
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
The magnetosphere of Saturn is the cavity created in the flow of the solar wind by the planet's internally generated magnetic field.Discovered in 1979 by the Pioneer 11 spacecraft, Saturn's magnetosphere is the second largest of any planet in the Solar System after Jupiter.

Map symbols can thus be categorized by how they suggest this connection: [6] [7] Iconic symbols (also "image", "pictorial", or "replicative") have a similar appearance to the real-world feature, although it is often in a generalized manner; e.g. a tree icon to represent a forest, brown denoting desert, or green denoting vegetation.
Among an endless stream of trends that pass in a flash and TikTok-viral recipes, dirty soda seems to have earned staying power for itself over the past year. Comprised of soda mixed with add-ins ...
