Latest Planetary atmospheres Stories
A group of electric-blue clouds are hovering over Antarctica right now, and NASA’s AIM spacecraft is helping scientists better understand them.
A long-standing mystery surrounding unusual warming of planetary atmospheres is not just exclusive to our solar system, but is most likely universal.
DeWayne Cecil, PhD, Reports on Human Health Effects of Global Warming for Founder of Bio Logic Aqua Research, Sharon Kleyne Grants Pass, OR (PRWEB) November
In a new study, researchers’ analysis of rock samples from the Archean era only deepen the mystery surrounding the origins of life on Earth.
Human influences have directly impacted the latitude/altitude pattern of atmospheric temperature.
A new analysis of near-infrared images taken by NASA's Cassini orbiter is providing more data about the composition of Saturn's atmosphere.
Using satellite data and computer models, NASA scientists were able to track and study the debris of the meteor that exploded over Chelyabinsk, Russia in February, giving them a better picture of how similar future events might affect the Earth’s atmosphere
The European Space Agency's (ESA) Venus Express spacecraft has revealed the winds on the second planet from the Sun have been getting faster over the last six years.
Noctilucent clouds (NLCs), tenuous cloud-like phenomena that form every summer in the skies above the North Pole, are forming earlier than usual.
To investigate how air pollution and natural emissions, which are pushed high into the atmosphere by large storms, affect atmospheric composition and climate, NASA’s DC-8 and ER-2 science aircraft will take flight over the southern US this summer.
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...
