Researchers detect heavy oxygen isotope in Earth's stratosphere

A study of the upper atmosphere's composition has successfully measured an increased presence of 18O, a heavier oxygen isotope with 10 instead of eight neutrons. Helmut Wiesemeyer (MPIfR Bonn) and his colleagues have measured ...

Ultracool dwarf binary stars break records

Northwestern University and the University of California San Diego (UC San Diego) astrophysicists have discovered the tightest ultracool dwarf binary system ever observed.

FAST telescope reveals unprecedented details of the Milky Way

The Milky Way is our home galaxy in the vast universe, but the structure and composition of the Milky Way remain mysterious. The vast interstellar space between the billions of stars is not empty, but filled with tenuous ...

Prospects for an all-optical remote magnetic field sensor

Crystals doped with rare-earth (RE) ions exhibit very narrow linewidths of optical transitions. The narrow-line spectra of triply ionized RE elements cover the entire visible and infrared range. RE-doped materials are widely ...

Gaia mission reveals the past and future of the sun

We all wish sometimes that we could see into the future. Now, thanks to the very latest data from ESA's star mapping Gaia mission, astronomers can do just that for the sun. By accurately identifying stars of similar mass ...

A sanitizer in the galactic center region

An international group of researchers led by Arnaud Belloche (MPIfR, Bonn, Germany) reports the first identification of iso-propanol in interstellar space, a substance which is used as a sanitizer on Earth. Iso-propanol is ...
