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.
Space Center Houston is a science museum that serves as the official visitor center of NASA Johnson Space Center in Houston, Texas. It was designated a Smithsonian Affiliate museum in 2014. The organization is owned by NASA, and operated under a contract by the nonprofit Manned Spaceflight Education Foundation, a 501(c)(3) organization.
As with Earth's magnetosphere, the boundary separating the solar wind's plasma from that within Saturn's magnetosphere is called the magnetopause. [2] The magnetopause distance from the planet's center at the subsolar point [note 1] varies widely from 16 to 27 R s (R s =60,330 km is the equatorial radius of Saturn).
The magnetosphere contains charged particles that are trapped from the stellar wind, which then move along these field lines. As the star rotates, the magnetosphere rotates with it, dragging along the charged particles. [13] As stars emit matter with a stellar wind from the photosphere, the magnetosphere creates a torque on the ejected matter.
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 ...
Science & Tech. Sports. Weather. 24/7 ... Uranus just a few days after the solar wind had squashed its magnetosphere - the planet's protective magnetic bubble - to about 20% of its usual volume ...
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 ...
Neptune, the smallest of its four gas planets, has a diameter of about 30,600 miles (49,250 km), roughly four times that of Earth. The newly discovered sub-Neptunes range from 1.9 to 2.9 times ...
