An ambitious mission by the Japan Aerospace Exploration Agency (JAXA) to make a new, high resolution map of the universe has just successfully returned its first pictures, and UK team members are delighted with the success. The AKARI (formerly ASTRO-F) infrared space telescope is making its All-Sky Survey at infrared wavelengths with sharper images and a much higher sensitivity than the first infrared astronomical sky survey satellite launched in 1983. AKARI will leave a tremendous legacy for the future of astronomy. Most of the light ever emitted in the Universe was emitted in the infra-red part of the spectrum, so the range of objects that can be studied by this survey is huge.
Today (May 22nd), at a press conference in Japan, JAXA released spectacular infra-red images of the Nebula IC 4954 that show the birth of stars in their cradle of formation.
“These first images are extremely promising,” said Dr. Stephen Serjeant, Senior Lecturer in Astrophysics at the Open University, said. ”The beautiful filigree structure in the nebula was impossible to see with the previous satellite IRAS. After having worked on this for so many years, it is wonderful to see our labours rewarded so clearly. AKARI can do many things that no other telescope on the Earth or in space can.”

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
