... Images of Clouds from Space . ... However, contemporary thinking suggests that the lower altitude cumulus clouds (such as pictures Thunderstorms, Brazil and Cumulus Cloud Tops ) have a net cooling effect on Earth's surface, reflecting heat back to space. ... Current data suggest that the cooling effects of great masses of cumulus storm clouds over the ocean at mid latitudes outweigh the heating effects of the upper-level cirrus clouds when considered on a global scale. ...

... We present a comparison of the surface density of young stars (неБ??) and dust surface density (неdust) across NGC 346 (N66) in 115 independent pixels of 6 ц? 6 pc2. ... We convert неdust to gas surface density (неgas) and неБ?? to star formation rate (SFR) surface densities (неSFR), using simple assumptions for the gas-to-dust mass ratio and the duration of star formation. ... On small scales the неSFR derived using Hн? systematically underestimates the count-based неSFR, by up to a factor of 10. ...

... Most sources say that this warming is due to friction between the meteoroid and the Earth's atmosphere, and that is partially true. ... Most meteoroids are smaller than a grain of rice" Meteors are the bright trails left by fragments of natural space debris called meteoroids (usually chunks of rock and iron) falling through the Earth's atmosphere. ... These are called meteorites. ... Belonging to a rare class of meteorite called pallasites, it was discovered locally by Steve Arnold. ...

Comet Lovejoy skimmed across the Sun's edge about 87,000 miles (140,000 kilometers) above the surface late December 15, 2011, furiously vaporizing as it approached the stellar surface and later emerged from the other side. It is the brightest sungrazing comet that SOHO and SDO have ever seen, with a nucleus about twice as wide as a football field. On approach, the comet's tail waggled as it interacted with the magnetic field of the Sun's atmosphere. ... SDO ...

... Today this year's largest group of sunspots will cross the Sun's central meridian. ... The next day, the number of spots in the group reached five, and the day after, on June 2nd, it was possible to count thirteen sunspots on solar disk, which had been clear prior to this. ... This year's two most powerful active areas, which passed across the solar disk at the beginning of May, 2009, are set to appear in the Sun's eastern sector in two days, on June 6th. ...

... Venus is a geologist's dream planet.' ... Because Venus is so similar in diameter and mass to our world, and also has a gaseous atmosphere, it has been called the Earth's "sister planet''. ... New radar images of Venus, just returned from NASA's Magellan spacecraft orbiting the planet, have provided astronomers the clearest view ever of its surface, revealing unique geological features, meteor impact craters, and evidence of volcanic eruptions different from any others found in the solar system. ...

... A more detailed (but qualitative) discussion of heat flow in the atmosphere and related weather processes, including the roles of buoyancy, convection and humidity. ... Heat makes it expand, it becomes less dense than the surrounding air and buoyant, and it rises like a hot-air balloon (or like a drop of oil in a bottle of water). ... The important thing to remember when dealing with convective flows, is that the higher one is in the atmosphere, the lower are the pressure and density of the air. ...

... We couldn't ask for better weather on planet Zoltex. ... These use information collected by satellites surrounding the Earth to monitor our weather. ... Now astronomers are starting to map the weather on other worlds well beyond our Solar System. Using very powerful telescopes, scientists have just created the first ever map of the weather on a brown dwarf! Using a clever technique astronomers were able to create a map of the dark and light patches on its surface. ...
