Clouds in the atmosphere of Venus are composed of tiny droplets of highly concentrated sulfuric acid. The V-shape of the clouds is due to the strong winds blowing near the equator. Because of the dense cloud layer, the Venusian surface can be observed only in radio and microwave bands and in some regions of the near infrared. This image of the Venusian surface was made by Pioneer Venus 1 in the ultraviolet rays in 1979. Credit: NASA
Exoplanet HD 189733 b. The weather on this world is deadly. Its winds blow up to 2 km/s at seven times the speed of sound. This scorching alien world possibly rains glass—sideways—in its howling winds. The cobalt blue color comes not from the reflection of a tropical ocean but rather a hazy, blow-torched atmosphere containing high clouds laced with silicate particles.
More remarkably, while Venus’s winds blow at speeds up to 250 miles per hour and clouds whip around the planet every four days, this gargantuan sideways smile did not move, but remained fixed above the ground for four days. Scientists from the mission are calling it a gravity wave.
The two small dark craters are brand new, having appeared in CTX images sometime between May 2007 and April 2008. They punched through a layer of bright dust and threw up some darker material, which the wind carried downwind (near-surface winds blowing from the southwest, and higher winds blowing from the southeast). Application of an atmospheric model could further constrain the season and time of day when the impact happened, based on the prevailing wind direction.
Cabarete is one of the original kitesurfing meccas, people have been making the pilgrimage to this amazing spot in the Dominican Republic for year. The wind blows consistently the year round and the waves roll in during the winter. You’ll find a relaxed cosmopolitan atmosphere and a town filled w
Geography for kids by KidsGeo.com ~ An indepth online geography textbook written for kids. Learn about the world around you. Geography is the study of the Earth as it exists today, focusing on the surface, the atmosphere, the oceans, as well as the distrubtion of plants, animals, and people.
Giant Blue Planet Discovered Astronomers using the NASA/ESA Hubble Space Telescope have, for the first time, determined the true color of a planet orbiting another star. If seen up close this planet, known as HD 189733b, would be a deep azure blue, reminiscent of Earth’s color as seen from space.
Researchers have detected a human fingerprint deep in the Borneo rainforest in Southeast Asia. Cold winds blowing from the north carry industrial pollutants from East Asia to the equator, with implications for air quality in the region. Once there, the pollutants can travel higher into the atmosphere and impact the ozone layer...
