Astronomers have used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe a disc around a young star in the Large Magellanic Cloud, a galaxy neighboring ours. It’s the first time such a disc, identical to those forming planets in our Milky Way, has ever been found outside our galaxy. The new observations reveal a massive [...]
An international research team led by Michael Kramer and Kuo Liu from the Max Planck Institute for Radio Astronomy in Bonn/DE have studied a rare species of ultra-dense stars, so called magnetars, to uncover an underlying law that appears to apply universally to a range of objects known as neutron stars. This law gives insight [...]
The RadioAstron mission opened a new window on the universe. Using a network of radio telescopes on Earth and in space, astronomers have captured the most detailed view ever of a jet of plasma shooting from a supermassive black hole at the heart of a distant galaxy. The jet travels at nearly the speed of [...]
An international team of scientists has delved into the heart of the Circinus Galaxy's active galactic nucleus using the Atacama Large Millimeter/submillimeter Array (ALMA). Achieving an unprecedented resolution of about one light-year, the research, led by Takuma Izumi (Assistant Professor at the National Astronomical Observatory of Japan), has illuminated the intricate dance of gas flows [...]

Astronomers at the Max Planck Institute for Extraterrestrial Physics (MPE) have succeeded in measuring the black hole mass from the motion of luminous gas that is seen swirling around Sagittarius A*, the black hole at the center of the Milky Way. It matches the measurement honoured with the Nobel Prize in Physics in 2020. Conclusion: [...]
An international team of scientists led by Dr Stuart Ryder/Macquarie University and Prof. Ryan Shannon/Swinburne University of Technology, has spotted a remote blast of cosmic radio waves lasting less than a millisecond. This 'fast radio burst' (FRB) is the most distant ever detected. Its source was pinned down by the European Southern Observatory’s (ESO) Very [...]
An international team of researchers led by Ph.D candidate Mark Snelders (ASTRON and University of Amsterdam) has discovered radio pulses that last only millionths of a second. With this it has been proven that previously discovered fast radio bursts (FRBs) can last even shorter than a thousandth of a second, giving life to the term [...]
An international research team led by Project Assistant Professor Satoshi Ohashi of the National Astronomical Observatory of Japan (NAOJ) has conducted high-resolution and multi-wavelength observations of a protoplanetary disk around a relatively young protostar, DG Taurus (DG Tau), using ALMA to study the structure of the disk and the size and amount of dust, the [...]
Using the NOEMA observatory, an international team of scientists has measured the precise distances for a large (135 sources) sample of the brightest galaxies selected from surveys done with the Herschel telescope. Robust values of the distances were derived for all sources, based on the detection of at least two emission lines for each object, [...]
