A conference to mark the first birthday of Hinode the joint British, American and Japanese space mission into the workings of the Sun will take place in Dublin this week.
A major aspect of the conference will be devoted to the new discoveries made possible by the Extreme Ultraviolet Imaging Spectrometer (EIS), designed and built by a team led by Professor Louise Harra from the UCL Mullard Space Science Laboratory (UCL MSSL). The EIS acts as a solar speed camera, and has recently been used to pinpoint the source of plasma that streams from the Sun during a solar flare, and provide new insights into coronal heating the mechanism that supercharges the temperature at the outer layer of the Sun.
Since 27 May, Europes scientists have free access to spectacular data and images from Hinode, a Japan-led mission with ESA participation that studies the mechanisms that power the Suns atmosphere and cause violent eruptions. This free access is now possible thanks to the opening of the Hinode Science Data Centre in Norway, developed and run by the Institute of Theoretical Astrophysics at the University of Oslo on behalf of ESA and the Norwegian Space Centre. It is part of ESA and Norways joint contribution to this solar mission.
A new movie from the Japanese Hinode spacecraft is one of the most detailed glimpses of a solar flare ever made and has helped scientists see what's behind the colossal eruption. The striking video, released this week, shows a major flare that lifted off the Sun on Dec. 13, 2006. The flare erupted from a sunspot catalogued as No. 930.

Hinode, the newest solar observatory on the space scene, has obtained never-before-seen images showing that the sun's magnetic field is much more turbulent and dynamic than previously known.
Taken by Hinode's Solar Optical Telescope on Nov. 20, 2006, this image reveals the structure of the solar magnetic field rising vertically from a sunspot, an area of strong magnetic field, outward into the solar atmosphere. At the edges of the sunspot the field lines bend over to reconnect with field of opposite polarity. Hinode JAXA/NASA
The restless bubbling and frothing of the Sun's chaotic surface is astonishing astronomers who have been treated to detailed new images from a Japanese space telescope called Hinode. The observatory will have as dramatic an impact on our understanding of the Sun as the Hubble Space Telescope has had on our view of the universe beyond, scientists told a NASA press conference in Washington, DC, US, on Wednesday.
"Everything we thought we knew about X-ray images of the Sun is now out of date. We've seen many new and unexpected things. For that reason alone, the mission is already a success" - Leon Golub from the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, US.
A NASA Science Update at 1 p.m. EDT Wednesday, March 21 will be held to discuss never-before-seen observations from an international mission studying the sun. The briefing will take place in the NASA Headquarters auditorium, 300 E Street, S.W., Washington. It will air live on NASA Television. The Hinode spacecraft, Japanese for "sunrise," launched in September 2006 to study the sun's magnetic field and how its explosive energy propagates through the different layers of the solar atmosphere. The spacecraft was known previously as Solar B.
Instruments aboard a Japan Aerospace Exploration Agency satellite named Hinode, or "Sunrise," are returning extraordinary new images of our sun. The international mission to study the forces that drive the violent, explosive power of the sun launched from Japan in September. Hinode is circling Earth in a polar flight path (a "sun-synchronous" orbit) that allows the spacecraft's instruments to remain in continuous sunlight for nine months each year. An international team of scientists and engineers is performing the calibration and checkout of Hinode's three primary instruments: the Solar Optical Telescope, the X-ray Telescope and the Extreme Ultraviolet Imaging Spectrometer. NASA made significant contributions to the development of these scientific instruments.
"The checkout phase is crucial because it allows controllers to confirm the spacecraft's instruments are working properly. As part of this checkout, we've been treated to some remarkable images of the sun" - John M. Davis, NASA project scientist at the Marshall Space Flight Centre, Huntsville, Alabama.
Hinode's X-ray Telescope has captured unprecedented details in solar active region corona, the sun's outer atmosphere. The corona is the spawning ground for explosive solar activity, such as coronal mass ejections. Powered by the sun's magnetic field, these violent atmospheric disturbances of the sun can be of danger to space travelers, disruptive to orbiting satellites and can cause power grid problems on Earth. Hinode's Solar Optical Telescope has delivered images that show greatly magnified views of the sun's surface. These images are revealing new details about solar convection. Solar convection is the process that drives the rising and falling of gases in the lowest atmospheric region, the photosphere. In addition, the Solar Optical Telescope is the first space-borne instrument to measure the strength and direction of the sun's magnetic field. The Solar Optical Telescope images and magnetic maps uncover highly dynamic, intermittent nature of the sun's lower atmosphere - chromosphere. It is also providing revolutionary views on various solar phenomena from heating of solar atmosphere to generation of magnetic fields and magnetic reconnection.
After its launch on 22 September 2006, the Hinode spacecraft is working successfully. JAXA are presenting movies of dynamic phenomena of the Sun demonstrating high performance of three telescopes on Hinode. One of the highlights is a dynamic eruption above a sunspot seen in Ca II H spectral line, which has been first discovered by Solar Optical Telescope (SOT). JAXA are confident that Hinode mission continue to bring astonishing scientific results.
