To observe the Sun at close range and measure its activity: with launch in February 2019, as part of the European Space Agency’s (ESA) Solar Orbiter spacecraft, STIX will study solar X-ray radiation in unprecedented detail. An international team with researchers from the Leibniz Institute for Astrophysics Potsdam (AIP) has developed STIX and now completed it. The AIP is the only German institute involved in this instrument.
STIX (short for Spectrometer/Telescope for Imaging X-rays) is designed to measure X-ray radiation emitted from the hot corona, the outer solar atmosphere. X-ray radiation as an indicator for magnetic solar activity.
STIX consists of windows in the heat shield, the imager and the detector box. X-ray radiation passes through the windows in the heat shield, it is subsequently filtered by the imager unit and finally detected by the detector box – in order to obtain images of the hottest regions of solar eruptions with temperatures of up to 40 million degrees Celsius.
AIP developed the fundamental imager design, machined actual flight parts, and supported the assembly and integration of the instrument. Furthermore, AIP accompanied the test campaign aimed to verify that the instrument can withstand strong vibration levels and large temperature fluctuations. It took about eight years to complete the STIX imager.
The German Space Agency (Deutsches Zentrum für Luft- und Raumfahrt, DLR) funded AIP with 1.8 million Euros for this project. Now, the international instrument team led by the Fachhochschule Nordwestschweiz (FHNW) has delivered STIX to Airbus Defence and Space (UK), where all instruments will be integrated into the Solar Orbiter spacecraft. Solar Orbiter is equipped with ten instruments to investigate the Sun and its environment.
Scientists hope to find answers to some of the Sun’s yet unanswered questions with STIX data. They will study how solar flares are generated and how they affect the interplanetary space, the Earth’s environment and our technical civilisation.
During Solar Orbiter’s ten year mission it will closely approach the Sun to about one quarter of the distance between Sun and Earth. It will even leave the ecliptic plane allowing for observations of the solar poles. Solar Orbiter will collect unprecedented data from perspectives never seen before.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
