Hinode’s solar data ready for Europe’s access

31.05.2007
Since 27 May, Europe’s 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 Sun’s 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 Norway’s joint contribution to this solar mission.

The other part of the joint contribution to Hinode consists of ground station coverage through the SvalSat downlink station at Svalbard, which nearly quadruples the data rate and thus significantly increases Hinode’s science return. Svalsat is the only station in the world that can receive Hinode’s data during each of its 15 daily orbits.

“Our European solar science community is extremely strong. We have several space missions with ESA leadership, or strong European participation, which are producing outstanding results about the Sun and its interaction with the planetary environment,” says Bernhard Fleck, ESA’s SOHO and Hinode Project Scientist.

“When ESA, in a joint venture with Norway, decided to contribute to Hinode, it was to broaden the possibilities for European scientists to participate in this exciting new mission and at the same time increase the science possibilities for the worldwide scientific community,” he continues.

In exchange for ESA’s and Norway’s contribution to the mission, European scientists have been guaranteed free access to the Hinode data by the Japan Aerospace Exploration Agency (JAXA).

“No doubt European scientists will make great use of this data and will produce excellent new science about our daylight star,” concludes Fleck.

The quality of data now available through the Hinode Science Data Centre can be appreciated in spectacular movies of the Sun, obtained by the XRT X-ray telescope on board, made public on 27 May by the National Astronomical Observatory of Japan (NAOJ).

The first X-ray movie was obtained between January and April 2007. It shows the medium-term evolution of the dynamic solar corona. The corona is a portion of the solar atmosphere that extends for millions of kilometres into space and is much hotter than the solar surface – a puzzle still not completely understood by scientists.

The second movie, obtained on 16 March 2007, provides a close-up view of X-ray-bright points in what is believed to be a quiet region of the Sun’s surface. The high resolution of the XRT instrument helped scientists see that these X-ray-bright points – widely distributed - are actually ‘loop’ structures demonstrating intense activity.

“Data like this, being gathered by Hinode since it started operating in October 2006, is a treasure chest for our scientists,” says Stein Vidar Hagfors Haugan, Executive Director of the data centre. “With the archiving system developed in our data centre, innovative in terms of contextual searching capability and speed, we believe we are providing a great contribution to maximising the scientific return of this new exciting mission.”

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
