A Roll Cloud Over Uruguay These rare long clouds may form near advancing cold fronts. In particular, a downdraft from an advancing storm front can cause moist warm air to rise, cool below its dew point, and so form a cloud. When this happens uniformly along an extended front, a roll cloud may form. Roll clouds may actually have air circulating along the long horizontal axis of the cloud. A roll cloud is not thought to be able to morph into a tornado. • Learn more: antwrp.gsfc.nasa.gov ? The Spotty Surface of Betelgeuse Betelgeuse really is a big star. If placed at the center of our Solar System it would extend to the orbit of Jupiter. But like all stars except the Sun, the red supergiant is so distant it usually appears as a single point of light, even in large telescopes. The intriguing picture shows two, large, bright, star spots. The spots potentially represent enormous convective cells rising from below the supergiant’s surface. They are bright because they’re hotter than the rest of the surface, but both spots and surface are cooler than the Sun. Betelgeuse is about 600 light-years away. • Learn more: antwrp.gsfc.nasa.gov ?

NASA Astronomy Pictures Of The Day [Week 2/2010]. — • www.youtube.com • www.youtube.com — ? The Spider and The Fly Bright clusters and nebulae abound in the ancient northern constellation of Auriga. The region includes the open star cluster M38, emission nebula IC 410 with Tadpoles, Auriga’s own Flaming Star Nebula IC 405, and this interesting pair IC 417 (lower left) and NGC 1931. An imaginative eye toward the expansive IC 417 and diminutive NGC 1931 suggests a cosmic spider and fly. About 10000 light-years distant, both represent young, open star clusters formed in interstellar clouds and still embedded in glowing hydrogen gas. • Learn more: antwrp.gsfc.nasa.gov ? Atlantis to Orbit The launch of a rocket bound for space is an event that inspires awe and challenges description.

Ancient Layered Hills on Mars What may appear to some as a terrestrial coastline is in fact a formation of ancient layered hills and wind-blown sand on Mars. The pictured region spans about three kilometers in Schiaparelli Crater. What created the layers of sediment is still a topic of research. The image was taken with the Mars Global Surveyor spacecraft. • Learn more: antwrp.gsfc.nasa.gov ?

“Water, Water Everywhere!” is Episode 2 in the six-part series “Tides of Change”, exploring amazing NASA ocean science to celebrate Earth Science Week 2009. To find out more visit climate.nasa.gov Want more? Subscribe to NASA on itunes! phobos.apple.com Or get tweeted by NASA: twitter.com Water is all around us, and its importance to nearly every natural process on earth cannot be underestimated. The water cycle is the movement of water around the Earth in all its forms, from the ocean to the atmosphere, to snow, soil, aquifers, lakes, and streams on land, and ultimately backs to the ocean. This video explains what the water cycle is and how important it is to life on earth.

This unique atom is the basic building block of life, and its compounds form solids, liquids, or gases. Carbon helps form the bodies of living organisms; it dissolves in the ocean; mixes in the atmosphere; and can be stored in the crust of the planet. A carbon atom could spend millions of years moving through this complex cycle. The ocean plays the most critical role in regulating Earths carbon balance, and understanding how the carbon cycle is changing is key to understanding Earths changing climate.

“Climate Change and The Global Ocean” is the first episode in the six-part series “Tides of Change”, exploring amazing NASA ocean science to celebrate Earth Science Week 2009. To find out more visit climate.nasa.gov Want more? Subscribe to NASA on itunes! phobos.apple.com Or get tweeted by NASA: twitter.com We know climate change can affect us, but does climate change alter something as vast, deep and mysterious as our oceans? For years, scientists have studied the world’s oceans by sending out ships and divers, deploying data-gathering buoys, and by taking aerial measurements from planes. But one of the better ways to understand oceans is to gain an even broader perspective – the view from space. nasa’s Earth observing satellites do more than just take pictures of our planet. High-tech sensors gather data, including ocean surface temperature, surface winds, sea level, circulation, and even marine life. Information the satellites obtain help us understand the complex interactions driving the world’s oceans today – and gain valuable insight into how the impacts of climate change on oceans might affect us on dry land.

In the last two decades, the rate of our world’s warming accelerated. Scientists predict that the globe will continue to warm over the course of the 21st century. Is this warming trend a reason for concern? After all, our world has witnessed extreme warm periods before, such as during the time of the dinosaurs. Earth …
