atmosphere
The gaseous layer that surrounds an astronomical body, such as a planet or a star. The ability of a planet to retain a substantial atmosphere depends on the strength of the planet's gravitational field and its temperature.

ATMOSPHERE (Gr. aTµos, vapour; o-q5aipa, a sphere), the aeriform envelope encircling the earth; also the envelope of a particular gas or gases about any solid or liquid.

Atmosphere Remote Sensing
Given a warm surface and a cool atmosphere, radiation detectors receive thermal radiation from the surface at transparent wavelengths and from various atmospheric heights at opaque wavelengths.
Atmosphere
and Interior
The atmosphere and (probably) the interior of Mars differ substantially from that of the Earth. The atmosphere is much less dense and of different composition, and it is unlikely that the core is molten.

The atmosphere that developed after primordial gases had been lost or had failed to accumulate is termed secondary.
THE ATMOSPHERE
Neptune's thick atmosphere consist of 74% hydrogen, 25% helium and about 1% methane. The atmosphere merges into the planet's mantle.
Io's Atmosphere
It would seem that Io should have a substantial atmosphere due to its numerous volcanoes spewing out massive amounts of gas and lava. Yet the first scientific observations seemed to indicate that Io had no atmosphere.
Saturn's Atmosphere
The sixth planet from the Sun in the solar system. Saturn orbits the Sun at an average distance of 9.5 AU. The planet has a mass 95.2 times the mass of Earth and a radius 9.45 times the radius of Earth.
THE EARTH'S ATMOSPHERE
The Earth's atmosphere is a thin layer of gases that surrounds the Earth. It composed of 78% nitrogen, 21% oxygen, 0.9% argon, 0.03% carbon dioxide, and trace amounts of other gases.
The Transparency of the Earth's Atmosphere
Electromagnetic radiation from space is unable to reach the surface of the Earth except at a very few wavelengths, such as the visible spectrum and radio frequencies.

The Sun Magnetic Fields Superheat Sun's Atmosphere
For decades, astronomers and mathematicians wondered why the atmosphere of the Sun is so much hotter than its surface. Now they've solved the mystery.
ATMOSPHERES
Astronomers have never observed any appreciable atmosphere on either the Moon or Mercury, either spectroscopically from Earth or during close approaches by spacecraft.
Atmosphere.
The Martian atmosphere consists of carbon dioxide (95 percent), nitrogen (2.7 percent), argon (1.6 percent), oxygen (0.2 percent), and trace amounts of water vapor, carbon monoxide, and noble gases other than argon.

Atmosphere
one atmosphere is 14.7 pounds per square inch (105 Newtons per square meter); the average atmospheric pressure at sea level on Earth. Atmosphere is also a layer of gases surrounding a planet, moon, or star.

atmosphere
The layer of gas which surrounds a celestial body. Stars, many planets, and a few satellites have atmospheres, and vary in their composition.

Atmosphere
(a) Mantle of gases round a star planet or moon, sometimes even forming the apparent surface of the body. For a body to retain an atmosphere depends on the body's gravity, and the temperature and composition of the gases.
Atmosphere
Fortunately for us, the Earth has an atmosphere and, of course, the other things that go with an atmosphere, such as rain, snow, sleet, hurricanes and all those other fun things.
The atmosphere
Saturn is composed of about 94% hydrogen and 6% helium. The clouds are composed of very small amounts of other chemical elements combined with hydrogen to give such compounds as ammonia, methane and phosphine.
High atmosphere turbulence is primarily associated with the jet stream, which is normally confined to latitudes above 30° north or south of the equator at altitudes of around 10 km.
The Earth's atmosphere is a layer of gases surrounding the planet Earth that is retained by the Earth's gravity. Dry air contains roughly 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.

The atmosphere is not static. The atmospheric turbulence makes the stars twinkle. It also scatters light, more on the blue light and less on the red. Thus, blue light cannot travel very far without changing direction in the atmosphere.
In an atmosphere (be it planetary or stellar), the scale height is the vertical distance over which the atmospheric pressure drops by a factor of e.
Ah, our atmosphere. It protects us, nourishes us, and gives us life. However, it also acts as a distorting filter when we view the sky. Another tutorial addresses the atmosphere's turbulence effects that reduce resolution of telescopes.
