Fuentes de energía para las plumas parecidas a géiseres de Tritón
Resumen
La luz solar puede estar impulsando plumas parecidas a géiseres en la luna de Neptuno Tritón. Un efecto invernadero de estado sólido, donde la radiación solar atrapada calienta el nitrógeno subterráneo, podría explicar las columnas observadas cerca del polo sur.
Área de la Ciencia:
- Ciencias planetarias Ciencias planetarias.
- Astrobiología Astrobiología.
- La geofísica es la geofísica.
Sus antecedentes:
- Tritón, la luna más grande de Neptuno, exhibe plumas activas parecidas a géiseres.
- Estas plumas se concentran cerca del polo sur, un área que experimenta luz solar continua durante su solsticio de verano.
Objetivo del estudio:
- Para investigar la hipótesis de que la insolación (radiación solar) impulsa las plumas tipo géiser de Tritón.
- Explorar los mecanismos por los cuales la energía solar podría alimentar estas características geológicas.
Principales métodos:
- Análisis de las propiedades de la superficie y los mecanismos de transferencia de energía en Tritón.
- Modelado de la transferencia de calor dentro de la superficie helada de Tritón, considerando los efectos de efecto invernadero en estado sólido.
Principales resultados:
- Se observaron cuatro penachos parecidos a géiseres cerca del polo sur de Tritón en regiones iluminadas por el sol.
- El efecto invernadero en estado sólido, que implica la radiación solar atrapada y la sublimación del hielo de nitrógeno, es una fuente de energía plausible.
- Tanto los modelos clásicos como los "súper" de invernadero que involucran capas de nitrógeno sólido son candidatos viables.
Conclusiones:
- La insolación es un probable conductor o desencadenante de las plumas parecidas a géiseres de Tritón.
- El efecto invernadero en estado sólido proporciona un mecanismo viable para la generación de penachos.
- El calor geotérmico, potencialmente aumentado por la insolación estacional, también puede contribuir a la actividad de las plumas.

Nuclear Fusion
The process of converting very light nuclei into heavier nuclei is also accompanied by the conversion of mass into large amounts of energy, a process called fusion. The principal source of energy in the sun is a net fusion reaction in which four hydrogen nuclei fuse and ultimately produce one helium nucleus and two positrons.
A helium nucleus has a mass that is 0.7% less than that of four hydrogen nuclei; this lost mass is converted into energy during the fusion. This reaction produces about...

Nuclear Transmutation
Nuclear transmutation is the conversion of one nuclide into another. It can occur by the radioactive decay of a nucleus, or the reaction of a nucleus with another particle. The first manmade nucleus was produced in Ernest Rutherford’s laboratory in 1919 by a transmutation reaction, the bombardment of one type of nuclei with other nuclei or with neutrons. Rutherford bombarded nitrogen-14 atoms with high-speed α particles from a natural radioactive isotope of radium and observed protons being...
Noble Gases
The elements in group 18 are noble gases (helium, neon, argon, krypton, xenon, and radon). They earned the name “noble” because they were assumed to be nonreactive since they have filled valence shells. In 1962, Dr. Neil Bartlett at the University of British Columbia proved this assumption to be false.
Nuclear Power
Controlled nuclear fission reactions are used to generate electricity. Any nuclear reactor that produces power via the fission of uranium or plutonium by bombardment with neutrons has six components: nuclear fuel consisting of fissionable material, a nuclear moderator, a neutron source, control rods, reactor coolant, and a shield and containment system.
Nuclear Fuels
Nuclear fuel consists of a fissile isotope, such as uranium-235, which must be present in sufficient quantity to provide a...

States of Water
Water exists in any one of the three classical states: solid (ice), liquid (water), and gas (steam or water vapor). The state of water depends on i) the intermolecular forces that draw molecules together and ii) the kinetic energy that leads to movements that pull them apart.
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...

The Sulfur Cycle
Sulfur, an important element in the chemical makeup of proteins, is recycled through the atmosphere and aquatic and terrestrial environments. Found in the atmosphere as sulfur dioxide (SO2), sulfur is released by decaying organisms, weathered rocks, geothermal vents, volcanos, and burning fossil fuels. It is deposited into the ecosystem, cycled through the biotic community, and either released back into the atmosphere as gas or deposited in marine sediment for long-term storage and eventual...
