Science (New York, N.Y.)
|August 9, 1991
Resumen
Los datos de la Voyager 2 revelan el planeta Neptuno.
Área de la Ciencia:
- Ciencias planetarias Ciencias planetarias.
- Dinámica de fluidos La dinámica de fluidos.
- La geofísica es la geofísica.
Sus antecedentes:
- La estructura y la composición del interior de Neptuno no se comprenden completamente.
- Los modelos anteriores se basaban en datos limitados, particularmente con respecto a su dinámica interna.
Objetivo del estudio:
- Para refinar los modelos del interior de Neptuno utilizando nuevos datos.
- Para investigar la relación entre la rotación de Neptuno y su campo gravitatorio.
Principales métodos:
- Análisis de los datos de la nave espacial Voyager 2 sobre las tasas de rotación de Neptuno y los armónicos gravitacionales.
- Experimentos de compresión por choque de laboratorio con materiales que simulan la composición de Neptuno ("hielo planetario").
- Comparación de datos experimentales con perfiles inferidos de densidad de presión de Neptuno y Urano.
Principales resultados:
- Los perfiles de densidad de presión interna de Neptuno muestran una similitud significativa con Urano.
- Los datos de choque para el "hielo planetario" son consistentes con las condiciones inferidas del interior de Neptuno.
- Los análisis indican que la rotación diferencial de Neptuno se limita a sus capas externas.
Conclusiones:
- La composición y estructura interior de Neptuno están mejor restringidas.
- La rotación diferencial juega un papel limitado en la distribución general de la masa de Neptuno.
- Los hallazgos apoyan las similitudes en la estructura interna de los gigantes de hielo.

02:06Newman Projections
Different notations are used to represent the three-dimensional structure of molecules on two-dimensional surfaces. One of the most commonly used representations is the dash-wedge formula. The dashed wedges, solid wedges, and the plane lines indicate the groups situated behind the plane, coming out of the plane, and in the plane, respectively.
The organic molecules rotate across the single bonds leading to numerous temporary three-dimensional structures of varying energy known as conformers.

01:45Mitochondrial Membranes
A single mitochondrion is a bean-shaped organelle enclosed by a double-membrane system. The outer membrane of mitochondria is smooth and contains many porins - the integral membrane transporters. Porins enable free diffusion of ions and small uncharged molecules through the outer mitochondrial membrane but limit the transport of molecules larger than 5000 Daltons. Further, the outer mitochondrial membrane forms a unique structure called membrane contact sites with other subcellular organelles,...
01:16Urethra
The urethra is a hollowed tubular organ through which urine is expelled from the body. This structure extends from the bladder to the external opening, allowing urine to be released.
The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male urethra is...

01:11Cerebrum: Anatomical Overview II
Each cerebral hemisphere can be divided into three main regions. The outermost region, the cerebral cortex, is a thin layer (2 to 4 millimeters thick) made up of gray matter, consisting of neuron cell bodies, dendrites, glial cells, and blood vessels. The middle region, or white matter, is primarily composed of myelinated nerve fibers organized into three types of large tracts: association fibers, commissures, and projection fibers. Association fibers connect different areas within the same...
01:19Structure of Amines
The hybridized nitrogen atom in amines possesses a lone pair of electrons and is bound to three substituents with a bond angle of around 108°, which is less than the tetrahedral angle of 109.5°. However, the C–N–H bond angle is slightly larger at 112°, with a carbon–nitrogen bond length of 147 pm. This carbon–nitrogen bond length of of amines is longer than the carbon–oxygen bond of alcohols (143 pm) but shorter than alkanes’ carbon–carbon bond (154 pm). These aspects are illustrated in Figure...
01:10Kepler'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,...
