Science (New York, N.Y.)
|October 19, 1984
Resumen
Los datos de la Voyager 1 revelan la estructura única del toro de Júpiter, compuesta por iones pesados de Io. Nuevas observaciones confirman componentes distintos y dinámicas de plasma dentro de la magnetosfera de Júpiter.
Área de la Ciencia:
- Ciencias planetarias Ciencias planetarias.
- Física del plasma es la física del plasma.
- La astrofísica es la astrofísica.
Sus antecedentes:
- La Voyager 1 exploró la magnetosfera interna de Júpiter en 1979 y fue la primera nave espacial en hacerlo.
- La nebulosa de Júpiter es un toro de iones originados por la actividad volcánica de Io.
- Estudios anteriores proporcionaron información inicial sobre este complejo entorno plasmático.
Objetivo del estudio:
- Para ampliar la comprensión de la magnetosfera de Júpiter utilizando nuevos datos.
- Para analizar las emisiones ópticas para la estructura detallada del toro.
- Para investigar la composición iónica y las variaciones de densidad.
Principales métodos:
- Análisis de los datos de las sondas magnetosféricas de la Voyager 1.
- Utilizando instrumentos de imagen refinados basados en la Tierra.
- Observando las emisiones ópticas [SIII] y [SII] de 1981-1983.
Principales resultados:
- Identificación de tres componentes distintos dentro del toro joviano.
- Se observaron regularidades en la partición de iones y densidades en toros externos e internos.
- Detallada estructura radial del plasma cerca de Io e inferida permanencia del frío toro interno.
Conclusiones:
- La magnetosfera de Júpiter exhibe un torus de plasma complejo y estructurado.
- Una nube neutral extendida es necesaria para reponer los iones en la nebulosa.
- La combinación de datos in situ y de teledetección ofrece una visión completa.

04:49Robbers Cave
During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension could be...
01:01Weightlessness
When an object is dropped, it accelerates toward the center of the Earth. If the net external force on the object is its weight, it is said to be in free fall; that is, the only force acting on the object is gravity. Galileo was instrumental in showing that, in the absence of air resistance, all objects fall with the same acceleration g. However, when objects on the Earth fall downward, they are never truly in free fall, because there is always some upward resistance force from the air acting...
01:04Travelling Waves
A wave is a disturbance that propagates from its source, repeating itself periodically, and is typically associated with simple harmonic motion. Mechanical waves are governed by Newton's laws and require a medium to travel. A medium is a substance in which a mechanical wave propagates, and the medium produces an elastic restoring force when it is deformed.
Water waves, sound waves, and seismic waves are some examples of mechanical waves. For water waves, the wave propagation medium is water;...

01:27Traveling Waves: Lossless Lines
The provided content explores the behavior of traveling waves on single-phase lossless transmission lines. It begins with a single-phase two-wire lossless transmission line of length Δx, characterized by a loop inductance LH/m and a line-to-line capacitance C F/m. These parameters result in a series inductance LΔx and a shunt capacitance CΔx.
01:27Latitudes and Departures
Latitudes and departures are essential concepts in surveying, providing a systematic way to analyze the projections of traverse lines. These projections allow surveyors to interpret a line's north-south and east-west components, which are crucial for precisely calculating areas, bearings, and lengths. Latitude is the north-south projection of a line, calculated as the product of the line's length and the cosine of its bearing. Departure, conversely, is the east-west projection obtained by...
01:23Actor-Observer Effect
The actor-observer effect, a cognitive bias closely linked to the fundamental attribution error, refers to the tendency for individuals to attribute their behavior to external, situational factors while explaining others’ behavior in terms of internal, dispositional traits. This asymmetry in attribution significantly influences social perception and judgment.Cognitive Mechanisms Behind the EffectTwo primary psychological mechanisms contribute to the actor-observer effect: differences in visual...
