Resumen

La Gran Mancha Roja de Júpiter (GRS) es un vórtice atmosférico masivo. Una nueva investigación que utiliza datos de la nave espacial Juno revela que el GRS no se extiende a más de 500 kilómetros en la atmósfera de Júpiter.

Área de la Ciencia:

Ciencias planetarias
Dinámica de fluidos
Ciencias atmosféricas

Sus antecedentes:

La Gran Mancha Roja de Júpiter (GRS) es el vórtice atmosférico más grande del Sistema Solar.
El GRS se ha observado durante más de dos siglos.
La profundidad del GRS por debajo de sus nubes visibles sigue siendo en gran medida desconocida.

Objetivo del estudio:

Para determinar la profundidad de la Gran Mancha Roja de Júpiter.
Para investigar la estructura vertical del GRS.

Principales métodos:

Análisis de datos de gravedad de 12 encuentros de la nave espacial Juno con Júpiter.
Sobrevuelo directo del GRS.
Medición de los cambios de velocidad en la línea de visión de las naves causados por anomalías de densidad del GRS.

Principales resultados:

Se detectaron anomalías de densidad localizadas asociadas con el GRS.
Dos métodos distintos para inferir la profundidad del GRS produjeron resultados consistentes.
El GRS está limitado a los 500 kilómetros superiores de la atmósfera de Júpiter.

Conclusiones:

La profundidad de la Gran Mancha Roja está limitada a los 500 km superiores de la atmósfera de Júpiter.
Las mediciones de gravedad proporcionan un nuevo método para sondear las estructuras atmosféricas de Júpiter.

Acceleration due to Gravity on Other Planets

Acceleration due to Gravity on Other Planets

The gravitational acceleration of an object near the Earth's surface is called the acceleration due to gravity. It can be measured by conducting simple experiments on Earth. However, such an experiment is impossible to conduct on the surface of other planets.
Astronomical observations are thus used to measure the acceleration due to gravity on other planets. This can be determined by observing the effect of a planet's gravity on objects close to it. The crucial factor that helps in this...

Gravity between Spherical Bodies

Gravity between Spherical Bodies

Newton's law of gravitation describes the gravitational force between any two point masses. However, for extended spherical objects like the Earth, the Moon, and other planets, the law holds with an assumption that masses of spherical objects are concentrated at their respective centers.
This assumption can be proved easily by showing that the expression for gravitational potential energy between a hollow sphere of mass (M) and a point mass (m) is the same as it would be for a pair of extended...

Kepler's Second Law of Planetary Motion

Kepler's Second Law of Planetary Motion

In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. His first law states that all planets orbit the Sun in an elliptical orbit, with the Sun at one of the ellipse's foci. Therefore, the distance of a planet from the Sun varies throughout its revolution around the Sun.
While in an elliptical orbit, the total energy of the planet is conserved. Therefore, the planet slows down when it is at apogee and...

Kepler's Third Law of Planetary Motion

Kepler's Third Law of Planetary Motion

In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. In 1909, he formulated his first two laws based on the observations of his forebears, Nikolaus Copernicus and Tycho Brahe. However, in 1918, he published his third law of planetary motion, which gives a precise mathematical relationship between a planet's average distance from the Sun and the amount of time it takes to revolve around the Sun. It...

Kepler's First Law of Planetary Motion

In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. He formulated his first two laws based on the observations of his forebears, Nikolaus Copernicus and Tycho Brahe.
Polish astronomer Nikolaus Copernicus put forth a theory that stated a heliocentric model for the solar system. According to this heliocentric theory, all the planets, including Earth, orbit the Sun in circular orbits.
On the other hand,...

Schwarzschild Radius and Event Horizon

Schwarzschild Radius and Event Horizon

No object with a finite mass can travel faster than the speed of light in a vacuum. This fact has an interesting consequence in the domain of extremely high gravitational fields.
The minimum speed required to launch a projectile from the surface of an object to which it is gravitationally bound so that it eventually escapes the object’s gravitational field is called the escape velocity. The escape velocity is independent of the mass of the object. Merging the idea of escape...
