Chandra Finds Possible Origin of ‘Treble Clef’ Waves

Astronomers have used NASA’s Chandra X-ray Observatory to break down the cause of a remarkable formation of radio waves they have nicknamed the “Treble Clef” because its distinct shape strongly resembles the musical symbol.

Chandra Finds Possible Origin of ‘Treble Clef’ Waves

Space-station cameras reveal how thunderstorms trigger gamma-ray bursts

Nature article: Mysterious electrical flashes above storm clouds have long puzzled scientists. “This is a game changer,” says Nikolai Østgaard, a space physicist at the University of Bergen in Norway. He described the findings in a pair of talks at the International Union of Geodesy and Geophysics meeting in Montreal, Canada, on 9 and 12 July. Picture: NASA/JSC

How do thunderstorms affect the Earth’s climate?

The Atmosphere-Space Interactions Monitor (ASIM) was launched last April in an effort to study severe thunderstorms. Just a year later, the observation facility is already providing scientists with a better understanding of the role that thunderstorms play in the Earth’s atmosphere and climate and how lightning is created.

Fireworks of blue lightning and gamma-rays above thunderclouds

After only one year in space, the Atmosphere-Space Interactions Monitor (ASIM) on the International Space Station has given researchers a new understanding of how lightning is created, and how thunderstorms can affect the atmosphere and the climate. Picture: ESA/NASA

New knowledge about giant lightning bolts in space

Measurements from the large ASIM space project shows a firework of blue lightning and X-ray radiation above thunderclouds. After one year in space, the ASIM (Atmosphere-Space Interactions Monitor) observatory on the International Space Station (ISS) has given researchers from Denmark’s Technical University (DTU) a new and better understanding of how lightning is created, and how thunderstorms can affect the stratosphere and the climate.

The Science Circling Above Us on the International Space Station

The International Space Station orbits Earth, 400 km above our heads, running scientific experiments that cannot be done anywhere else. Read on for our bi-weekly update on European science in space. Picture: ESA

ASIM observatory now installed

DTU is looking forward to receiving data from the ASIM space observatory, which was installed on the International Space Station (ISS) last weekend. Picture: ESA/P.Thomsen

Congratulations to ASIM launch and installation

IDEAS congratulates the University of Bergen, the Birkeland Centre for Space Science, Terma AS and the Technical University of Denmark with the successful launch and installation of the ASIM instrument featuring the MXGS gamma ray detector on the International Space Station.

New atmosphere instrument on International Space Station looking for thunderstorms

On Friday, April 13, 2018, the Danish ASIM experiment will be installed on the outside of the European Columbus module of the ISS International Space Station. The instrument must give us insight into the luminous phenomena that take place over violent thunderstorms. The Belgian B.USOC is responsible for the infrastructure and operations of ASIM.
