Latest Planetary atmospheres Stories
Scientists widely accept that around 2.4 billion years ago, the Earth's atmosphere underwent a dramatic change when oxygen levels rose sharply.
A UC Riverside-led study reports on the effects of biological oxygen production nearly 100 million years before oxygen accumulated in the atmosphere.
LEHIGH VALLEY, Pa., Oct. 29 /PRNewswire-FirstCall/ -- Air Products (NYSE: APD) today announced plans to build a new world-scale air separation unit (ASU) at its La Porte, Texas industrial gases facility.
Right now, the Moon is a ghost town. Nothing stirs. Here and there, an abandoned Apollo rover â€” or the dusty base of a lunar lander â€” linger as silent testimony to past human activity.
Observations by the European Space Agencyâ€™s Venus Express mission have provided strong new evidence that the solar wind has stripped away significant quantities of water from Earthâ€™s twin planet.
Since its discovery by Dutch astronomer Christiaan Huygens in 1655, Saturn's most massive moon, Titan, has been known as a place of mystery and intrigue.
Researchers from NCAR have created the first-ever model to simulate the impact of the sunâ€™s radiation fluctuations on the earthâ€™s climate.
Subtle connections between the 11-year-solar cycle, the stratosphere and the tropical Pacific Ocean work in sync to generate periodic weather patterns that affect much of the globe, according to research results appearing this week in the journal Science.
Our sun does not radiate evenly. The best known example of radiation fluctuations is the famous 11-year cycle of sun spots. Nobody denies its influence on the natural climate variability, but climate models have, to-date, not been able to satisfactorily reconstruct its impact on climate activity.
When Planet Earth was just cooling down from its fiery creation, the sun was faint and young. So faint that it should not have been able to keep the oceans of earth from freezing.
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...
