On Earth, the brightest auroras (the high - altitude glows often called the northern and southern lights) are generated when electrons in
outer space near Earth are accelerated by large electrical potentials, or voltages, along the lines in our
planet's magnetic field and slam into gas molecules in the upper
atmosphere above polar regions.
Forming in the system's colder
outer regions, where volatile compounds such as water and carbon dioxide freeze out, makes it possible that the
planets incorporated those ices and carried them along to a warmer place where they could melt, evaporate, and become oceans and
atmospheres.
The collection will help scientists to better understand not only how the
atmospheres of the
outer planets function, but also the
atmospheres of Earth and
planets beyond the solar system.
The images, taken over a 10 - hour period, created two massive maps of the entire
planet, allowing scientists to measure the speeds of Jupiter's winds, identify different events in its
atmosphere, and track changes in the
outer layers of the
planet.
The new data also give scientists clues to a long - standing mystery about the
atmospheres of giant
outer planets.
Phosphine forms in the hot interior of the
planet and reacts to form other compounds in the cooler
outer atmosphere, so its appearance in the spectrum is evidence of turbulent mixing in Jupiter's
atmosphere.
Using the Hubble Space Telescope, astrophysicist Alfred Vidal - Madjar of the Institute for Astrophysics in Paris detected starlight streaming through the
planet's
outer layers and determined that its
atmosphere is boiling off, creating a large cloud.
The point at which a
planet's
atmosphere would experience runaway greenhouse - gas effects like those seen on Venus — a point located just inside Earth's orbit in our solar system — forms the
outer boundary.
He eliminates the
outer planets (too cold); Mercury (too hot on the sunny side and too cold on the other); and the Moon and asteroids (their gravities are too weak to trap
atmospheres).
Its ultraviolet light detectors will reveal the composition of interstellar gas, the cores of galaxies and quasars, the
outer atmospheres of cool stars and
planets, planetary nebulas, and supernovas.
As the exoplanet passes in front of its host star, as seen from Earth, some of this starlight travels through the
planet's
outer atmosphere.
The hydrogen and oxygen coronas of Mars are the tenuous
outer fringe of the
planet's upper
atmosphere, where the edge of the
atmosphere meets space.
Taking observations from twin telescopes mounted on the noses of the planes, Caspi will capture the clearest images of the Sun's
outer atmosphere — the corona — to date and the first - ever thermal images of Mercury, revealing how temperature varies across the
planet's surface.
Comets from
outer space may have created Earth's
atmosphere — not volcanoes spewing out gases from deep within the
planet.
One goal is to add a thin, stable layer of fluid on top of the spinning water, which would function like the thin
outer layer of Jupiter's
atmosphere that's responsible for the
planet's weather.
Since
planet b is gaseous, however, its
outer atmosphere is probably circulating much faster than its interior.
Because
planet b is tidally locked and the
outer atmosphere is so efficient at re-radiating heat, its «nightside» stays dark and cold (top), unlike bands of even temperature on a Jupiter - like
planet (shown below — more).
Such a large temperature difference indicates that the
planet's
atmosphere absorbs and re-radiates starlight so quickly that the gas circling around it in the
outer atmosphere cools off quickly — unlike Jupiter, which appears to have a relatively even temperature within planetary bands of atmospheric circulation.
Called «NASA's Leadership and America's Future in Space,» the report said that studying the
outer gas giant
planets (such as Saturn) help scientists learn about their
atmospheres and internal structure.
In view of future missions to the
outer Solar System, an accurate identification of the space weather conditions around a
planet can contribute significantly in the estimation of the water abundances in the planetary
atmospheres and their long - and short - term variability.
I'm still holding out for the news that reads: «Second Earth Found» -[this exoplanet] will have all the right ingredients: orbit its star inside the habitable zone, spectroscopic analysis will reveal a nitrogen - rich
atmosphere, evidence of water, roughly the same mass as our
planet and it will belong in a system with a couple of gas giants shepherding the
outer system.
The
outer planet could have developed a thick water vapour
atmosphere.
«The composition and chemistry of ice giant
atmospheres provides clues about their formation, evolution and current state,» explained a research paper referenced as part of NASA's
Outer Planets Assessment Group Meeting in Laurel, Maryland.
The
outer atmosphere will expand significantly, and
planet Earth will lie within the Sun's photosphere (the part of the Sun that is not transparent to light).
This might mean that it has a hot
outer atmosphere heated by bubbling convection cells on the young
planet — sort of a Jupiter on steroids.
«And there isn't enough free oxygen in the
atmospheres of the
outer planets to allow that to happen.»
We know that the magnetosphere is filled with plasma from solar wind but for more than two decades it has been theorised that the innermost part of the Earth's magnetosphere — a region centred around the Earth's equator and surrounding our
planet's
atmosphere known as the plasmasphere — also plays a vital role in replenishing the
outer magnetosphere with fresh plasma.
We've heard a lot about the fabled Star Citizen alpha build 3.0, and we've been shown a lot of spectacular sights from it - spaceships careering down from
outer space through
atmospheres and onto the surface of
planets.
But that's actually an understatement by Gallup, since more than 97 % of the world's climatologists say that those carbon gases, which are given off by humans» burning of carbon - based fuels, are causing this
planet's temperatures to rise over the long term, as those carbon gases accumulate in the
atmosphere and also block the heat from being radiated back into
outer space.
Thus heat from the Sun «creeps» up the temperature gradient in the
atmosphere, and then further up the steeper temperature gradient in the
outer crust, and even further through the mantle until, whether you choose to believe it or not, it actually supports the core temperature, preventing the core from cooling off, even on
planets like Uranus where no energy is created in the core.
