Cluster has spent a decade revealing previously hidden interactions between the Sun and Earth. Its studies have uncovered secrets of aurora, solar storms, and given us insight into fundamental processes that occur across the Universe. And there is more work to do.

GAINESVILLE, Fla. --- Any driver who’s seen deer silhouetted by the headlights of an oncoming car knows that vital information can be conveyed by the outlines of objects. GAINESVILLE, Fla. — Any driver who’s seen deer silhouetted by the headlights of an oncoming car knows that vital information can be conveyed by the outlines of objects. Building on this concept, University of Florida astronomers have analyzed light passing through the upper atmosphere of the giant planet HD 80606 b, about 190 light years from Earth, and determined that its atmosphere contains the element potassium. “It’s wonderful that this method works so well for Jupiter-sized planets,” said Knicole Colón, a UF astronomy doctoral student. “Now, we’re working to apply this technique to observe smaller planets in an effort to pinpoint the components of their atmospheres.” Coincidentally, another team led by David Sing at the University of Exeter, in Devon, U.K., has just used the same technique to detect potassium in the atmosphere of XO-2b, another huge planet about 485 light years from Earth. Both planets, known as gas giants, have extremely high temperatures by earthly standards – HD 80606 b reaches about 2,200 degrees Fahrenheit and XO-2b is about 1,700 degrees. ...

The explosion of a massive star blazes with the light of 200 million Suns in this Hubble Space Telescope image. The arrow at top right points to the stellar blast, called a supernova. The supernova is so bright in this image that it easily could be mistaken for a foreground star in our Milky Way Galaxy. And yet, this supernova, called SN 2004dj, resides far beyond our galaxy. Its home is in the outskirts of NGC 2403, a galaxy located 11 million light-years from Earth. Although the supernov [...]

Pity poor Mercury. The tiny planet endures endless assaults by intense sunlight, powerful solar wind and high-speed miniature meteoroids called micrometeoroids. The planet's flimsy covering, the exosphere, nearly blends in with the vacuum of space, making it too thin to offer protection. Because of this, it's tempting to think of Mercury's exosphere as just the battered remains of ancient atmosphere. Really, though, the exosphere is constantly changing and being renewed with sodium, potas [...]

In December 1983, the National Science Foundation's Division of Policy Research and Analysis enlisted Science Applications Incorporated (SAI) of McLean, Virginia, to compare the science and technology research potential of an Earth-orbiting space station and a base on the moon. In its report, which was completed on January 10, 1984, SAI cautioned that, because its study was performed "in a very short two-week period," it could offer only "a preliminary indication" of the relative merits of a space station in low-Earth orbit (LEO) and a lunar base. Though SAI did not say so, the study had a short turnaround time because its results were meant to be made available to the White House ahead of President Ronald Reagan's planned announcement of a NASA space station program during the January 1984 State of the Union Address. SAI explained that its study had used a four-step approach. First, the study team had judged which science and technology disciplines could best be served by an LEO space station and which by a lunar base. Next, the team had developed a lunar base conceptual design capable of serving the disciplines it identified. It then had developed a transportation system concept for deploying and maintaining ...

Over the last few days, we have focused on the geology and volcanic history of Tvashtar Paterae, a string of four volcanoes located within Io's high northern latitudes. During the Galileo mission, Tvashtar was the site of several volcanic eruptions between November 1999 and October 2001, including a large, sulfur-rich plume that was seen by Cassini during its brief flyby in late December 2000. Since the end of the Galileo mission in 2003, monitoring of active volcanism on Io was limited to intermittent data taken at ground-based telescopes like the European Southern Observatory in Chile, Keck II, and IRTF in Hawaii. In addition, in late February 2007, the Pluto-bound New Horizons spacecraft flew by Io from a distance of 2.26 million kilometers (1.4 million miles), allowing the cameras on-board to search for surface changes on the moon since it was last seen five years earlier. Today, we will discuss the volcanic activity seen at Tvashtar since the end of the Galileo mission as what this volcanic history tells us about the variety of eruption styles exhibited by the volcanoes of Tvashtar and how their lavas are fed.Don't forget to check out the previous two parts of our series on Tvashtar ...

British physicist Stephen Hawking's latest book is already making waves with his observation that science can explain the universe's origin without invoking God. Rodger Bosch / AFP - Getty Images filePhysicist Stephen Hawking delivers a lecture in South Africa in 2008. In a new book, he says science doesn't need God to explain the origin of the universe. British physicist Stephen Hawking's latest book is already making waves with his observation that science can explain the universe's origin without invoking God. "Because there is a law such as gravity, the universe can and will create itself from nothing," Hawking and his co-author, Caltech physicist Leonard Mlodinow, write in "The Grand Design," which is due to be issued next week. "Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist. It is not necessary to invoke God to light the blue touch paper and set the universe going." That's the quote that lit the match in The Guardian as well in The Times of London, which published an excerpt from the book in its Thursday edition. But by itself, the quote doesn't have much "there" there. If Hawking is saying merely that something ...

We're in the Second Life rover yard this morning, preparing for a D-RATS mixed reality event from the Arizona Black Rock volcanic field. We'll stream the live, real-world webcast into Second Life's social media 3-D world to create an immersive, participatory experience for the Second Life community. The rover yard in Second Life replicates NASA rover activities so users can share in NASA's compelling story of science and exploration. Mission concepts and technology models are available to everyone in this hands-on, distance-learning environment. Second Life residents are telepresent as they work together and communicate about the design, analysis and performance of space technology and events. This feeling of telepresence creates a collaborative bond that fosters engagement, conversation, feedback and learning. More at NASA Blogs read more
