Liquid-metal experiment provides insight into the heating mechanism of the sun's corona
Monday, 03 January 2022 18:50
Why the sun's corona reaches temperatures of several million degrees Celsius is one of the great mysteries of solar physics. A "hot" trail to explain this effect leads to a region of the solar atmosphere just below the corona, where sound waves and certain plasma waves travel at the same speed. In an experiment using the molten alkali metal rubidium and pulsed high magnetic fields, a team from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), a German national lab, has developed a laboratory model, and for the first time experimentally confirmed the theoretically predicted behavior of these plasma waves—so-called Alfvén waves—as the researchers report in the journal Physical Review Letters.

Video: Orbital badminton in 360 degrees
Monday, 03 January 2022 12:49
Experience an orbital badminton match on the International Space Station ISS in 360° as ESA astronaut Matthias Maurer challenges his crewmates and Japanese spaceflight participants Yusaku Maezawa and Yozo Hirano.
Together with Roscosmos cosmonaut Alexander Misurkin, the Japanese spaceflight participants joined the current Expedition 66 crew for a short-term stay of 12 days on the ISS.
While their stay on the ISS focuses on scientific and operational activities, the astronauts on board the Space Station also enjoy recreational activities that provide an important balance for the crew and offer opportunities for intercultural exchange and team building.
Matthias was launched to the International Space Station on Crew Dragon Endurance as part of Crew-3 at 02:03 GMT/03:03 CET Thursday 11 November 2021. His ESA mission on board is known as Cosmic Kiss and will see him live and work for approximately six months in orbit.
