Drop In Radiation Can Trigger Cold Winters
2011-10-11 04:33:48

According to a new study, a drop in the sun's radiation can trigger unusually cold winters in parts of North America and Europe. The scientists said this finding could improve long-range forecasts and help countries prepare for blizzards. Previously, researchers were just able to see a weak link between solar activity and winter weather.  However, the new study used satellite measurements from NASA's Solar Radiation and Climate Experiment (SORCE) to reveal that differences in UV...

Image 1 - Scientists To Study Indian Ocean Oscillation For Long-Term Weather Forecasting
2011-09-23 06:05:47

  Scientists from all over the world will be gathering in the Indian Ocean starting next month to study the Madden-Julian Oscillation. This disturbance originates in the equatorial Indian Ocean every 30 to 90 days and is part of the Asian and Australian monsoons, can enhance hurricane activity in the northeast Pacific and Gulf of Mexico, trigger torrential rainfall along the west coast of North America and affect the onset of El Nino. The campaign, known as DYNAMO (Dynamics of the...

The Secret Lives Of Solar Flares

  [ View the Video ] One hundred and fifty two years ago, a man in England named Richard Carrington discovered solar flares. It happened at 11:18 AM on the cloudless morning of Thursday, September 1st, 1859. Just as usual on every sunny day, the 33-year-old solar astronomer was busy in his private observatory, projecting an image of the sun onto a screen and sketching what he saw. On that particular morning, he traced the outlines of an enormous group of sunspots. Suddenly,...

Solar Dynamics Observatory Observes New Solar Flare Characteristics
2011-09-08 06:06:56

  NASA's Solar Dynamics Observatory, or SDO, has provided scientists new information about solar flares indicating an increase in strength and longevity that is more than previously thought. Solar flares are intense bursts of radiation from the release of magnetic energy associated with sunspots. They are the solar system's largest explosive events and are seen as bright areas on the sun. Their energy can reach Earth's atmosphere and affect operations of Earth-orbiting...

Gas giant may hold keys to understanding solar system formation, evolution Several University of Colorado Boulder faculty and students are participating in NASA's Juno Mission to Jupiter, now slated for launch Aug. 5 from Florida's Kennedy Space Center and which is expected to help steer scientists toward the right recipe for planet-making. The primary goal of the mission is to understand the origin and evolution of the massive gas planet, said CU-Boulder Professor Fran Bagenal of the...

The Mars Atmosphere and Volatile EvolutioN (MAVEN) mission reached a major milestone last week when it successfully completed its Mission Critical Design Review (CDR). MAVEN, scheduled for launch in late 2013, will be the first mission devoted to understanding the Martian upper atmosphere. The goal of MAVEN is to determine the history of the loss of atmospheric gases to space through time, providing answers about Mars climate evolution. It will accomplish this by measuring the current rate of...

Scientists say they have found convincing evidence that Saturn's moon Enceladus has a large-scale subterranean saltwater ocean. The discovery was made using data collected during the Cassini-Huygens mission to Saturn. The plumes of shooting water vapor and tiny grains of ice into space were originally discovered emanating from Enceladus by the Cassini spacecraft in 2005. The researchers from the University of Heidelberg and University of Colorado said during three of Cassini's passes...

High up in the sky near the poles some 50 miles above the ground, silvery blue clouds sometimes appear, shining brightly in the night. First noticed in 1885, these clouds are known as noctilucent, or "night shining," clouds. Their discovery spawned over a century of research into what conditions causes them to form and vary "“ questions that still tantalize scientists to this day. Since 2007, a NASA mission called Aeronomy of Ice in the Mesosphere (AIM) has shown that the cloud...
