Latest Planetary atmospheres Stories
NASA researchers are about to fly off on a campaign that will take them into the heart of thunderstorm country.
In a world first, the sounds of Mars and Venus are revealed as part of a planetarium show in Hampshire this Easter.
Fossilized raindrop impressions have shown scientists evidence of greenhouse gases in Earth’s early atmosphere.
A recent flurry of eruptions on the sun did more than spark pretty auroras around the poles. NASA-funded researchers say the solar storms of March 8th through 10th dumped enough energy in Earth’s upper atmosphere to power every residence in New York City for two years.
Earth’s early atmosphere may have flipped between two sates before oxygenation, according to a new study.
Clouds have a profound effect on the climate, but we know surprisingly little about how they form.
Humans pump thousands of tons of vapor from the metallic element mercury into the atmosphere each year, and it can remain suspended for long periods before being changed into a form that is easily removed from the atmosphere.
Scientists in the New York Center for Astrobiology at Rensselaer Polytechnic Institute have used the oldest minerals on Earth to reconstruct the atmospheric conditions present on Earth very soon after its birth.
TAU researchers predict "sprites" in the atmospheres of Jupiter, Saturn, and Venus.
At first glance, a weather forecaster for Venus would have either a really easy or a really boring job, depending on your point of view.
Earth's Atmosphere -- Earth's atmosphere consists of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (variable, but around 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. 75% of the atmosphere exists within 11km of the planetary surface. Temperature and the Atmospheric Layers The temperature of the Earth's atmosphere...
Sky -- Although almost everyone have seen it, sky is hard to be defined precisely. Generally, sky is the space seen when one looks upward from the surface of a planet. Some people define sky as the denser gaseous zone of a planet's atmosphere. Clouds, rainbows and weather all occur amongst a planet's sky. In astronomy, the sky is divided into many regions, called constellations. The blue colour of the daytime sky results from the selective scattering of light rays. When the sunlight...
Saturn's moon Titan -- Titan is the planet Saturn's largest moon. It is larger than either of the planets Mercury or Pluto and is the second-largest moon in the solar system after Ganymede (it was originally thought to be slightly larger than Ganymede, but recent observations have shown that its thick atmosphere caused overestimation of its diameter). Titan was discovered on March 25, 1655 by the Dutch astronomer Christian Huygens, making it one of the first non-terrestrial moons to be...
