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.
According to NASA, Earth's magnetosphere and the Sun's magnetic field are constantly pressed against one another on the dayside of Earth. Approximately every eight minutes, these fields briefly merge, forming a temporary "portal" between the Earth and the Sun through which high-energy particles such as solar wind can flow. The portal takes the ...
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 .
The Planets, retitled The Planets and Beyond for its second season, is a documentary television series produced by the Science Channel that aired from 2017 to 2019. It explores the planets and of the Solar System , exoplanets , and other astronomical objects .
The magnetosphere of Jupiter is the cavity created in the solar wind by Jupiter's magnetic field.Extending up to seven million kilometers in the Sun's direction and almost to the orbit of Saturn in the opposite direction, Jupiter's magnetosphere is the largest and most powerful of any planetary magnetosphere in the Solar System, and by volume the largest known continuous structure in the Solar ...
The planet's magnetosphere, though small enough to fit within Earth, [97] is strong enough to trap solar wind plasma. This contributes to the space weathering of the planet's surface. [104] Observations taken by the Mariner 10 spacecraft detected this low energy plasma in the magnetosphere of the planet's nightside. Bursts of energetic ...
Cox starts this episode in Al-Qayrawan, Tunisia to analyse the orbit of the planets around the Sun, with details on how the 23-degree tilt of the Earth creates the seasonal weather patterns. He also visits the Atlas Mountains , and relates how in clear night skies the ancients observed the rotation of the stars and the retrograde and prograde ...
Voyager 2 has since crossed the heliopause into interstellar space. Voyager 1 and 2 speed and distance from Sun. The heliosphere is the area under the influence of the Sun; the two major components to determining its edge are the heliospheric magnetic field and the solar wind from the Sun. Three major sections from the beginning of the ...
