Deepest look yet into the heart of a quasar
International team observes innermost structure of quasar 3C 273 At the core of almost every galaxy is a supermassive black hole. But there are many different types. Quasars, for example, are one of the brightest and most active types of galaxy centres. An international group, including researchers from the Max Planck Institute for Radio Astronomy in Bonn, presents new observations of the first quasar ever identified.

Catching the dynamic Coronal Web
Researchers discover an important clue as to what mechanism drives the solar wind Using observational data from the U.S. weather satellites GOES, a team of researchers led by the Max Planck Institute for Solar System Research (MPS) in Germany has taken an important step toward unlocking one of the Sun-s most persevering secrets: How does our star launch the particles constituting the solar wind into space? The data provide a unique view of a key region in the solar corona to which researchers have had little access so far.

A sharp look into the nucleus of a quasar
International team observes the innermost structure of the jet of 3C 273 At the core of almost every galaxy is a supermassive black hole. But there are many different types. Quasars, for example, are one of the brightest and most active varieties of galactic centers. An international group, including researchers from the Max Planck Institute for Radio Astronomy in Bonn, Germany, presents new observations of the first quasar ever identified.

Black holes in eccentric orbit
A research team from Jena and Turin (Italy) has reconstructed the origin of an unusual gravitational wave signal. As the researchers write in the current issue of the scientific journal "Nature Astronomy", the signal GW190521 may result from the merger of two massive black holes that captured each other in their gravitational field and then collided while spinning around each other in a rapid, eccentric motion (DOI: 10.1038/s41550'022 -01813-w).

IceCube neutrinos give us first glimpse into the inner depths of an active galaxy
Mainz-based scientists have been members of the IceCube consortium since 1999 For the first time, an international team of scientists found evidence of high-energy neutrino emission from NGC 1068, also known as Messier 77, an active galaxy in the constellation of Cetus and one of the most familiar and well-studied galaxies to date.

New method finds black hole closest to Earth
The finding promises numerous similar discoveries Using data from ESA-s Gaia astrometry mission, astronomers have identified the closest known black hole, less than 1600 light-years away from Earth, and determined its mass. The black hole is orbiting a star similar to our Sun, and was identified by tracking the star that the black hole is orbiting.

Wobbling like a spinning-top - surprising observations of X-ray pulsar
An X-ray pulsar is a rotating magnetized neutron star. The very first direct measurement of the polarization of an X-ray pulsar by the Imaging X-ray Polarimetry Explorer (IXPE) space telescope has challenged previous models of such systems. The degree of polarization of the X-ray pulsar Hercules X-1 was much lower than theoretically predicted, so astrophysicists are now having to reconsider their basic ideas about the geometry and structure of matter flows.

Lightest-ever neutron star or strange quark matter?
The lightest neutron star so far found is located at the center of the supernova remnant HESS J1731'347 . Dr. Victor Doroshenko, Dr. Valery Suleimanov, Dr. Gerd Pühlhofer and Professor Andrea Santangelo from the High Energy Astrophysics section of the University of Tübingen's Institute of Astronomy and Astrophysics discovered the unusual object with the help of X-ray telescopes in space.

Astronomy: Observation puzzles researchers
Finding cannot be explained by classical assumptions. Study under the leadership of the University of Bonn An international team of astrophysicists has made a puzzling discovery while analyzing certain star clusters. The University of Bonn played a major role in the study. The finding challenges Newton's laws of gravity, the researchers write in their publication.

Asteroid Ryugu: Arrived from the edge of the solar system
The asteroid Ryugu probably formed at the outer edge of the solar system beyond the gas giants Jupiter and Saturn. This conclusion is suggested by high-precision measurements that determine the ratio of different iron isotopes in rock samples from Ryugu. An international research group with participation of the Göttingen MPI for Solar System Research (MPS) and the University of Göttingen reports these results in the journal Science Advances .

A Traveler from the Edge of the Solar System
Iron isotopes in samples from asteroid Ryugu suggest its origin to lie beyond the orbits of Jupiter and Saturn The asteroid Ryugu likely formed at the outer edge of the Solar System beyond the orbits of Jupiter and Saturn, as high-precision measurements that determine the ratio of iron isotopes in rock samples from Ryugu suggest.

Gigantic Radio Sources Discovered in the Universe-Up to 10 Million Light Years in Size
An international research team led by the Hamburg Observatory of Universität Hamburg has discovered 4 gigantic radio sources. These so-called megahalos are up to 10 million light years in size but have been detected for the first time with the help of the Low-Frequency Array (LOFAR) radio telescope.

What the ’prey’ of a peregrine falcon tells us about the beginnings of our solar system
An international research team led by Tomoki Nakamura (Tohoku, Japan) has studied soil samples collected by the Japanese spacecraft Hayabusa-2 on the asteroid Ryugu. Falko Langenhorst of Friedrich Schiller University in Jena, Germany, was part of the group that gained insights into the formation of the asteroid and the unique processes that took place during the first five million years after the birth of our solar system from the analysis of the extraterrestrial material.

Gas bubble swirls around the heart of the Milky Way
Researchers discover a hot spot near the Sagittarius A* black hole with the Alma radio telescope. There is a black hole in the center of our Milky Way. In the immediate vicinity of this mass monster called Sagittarius A*, things are turbulent. Now, an international group led by Maciek Wielgus of the Max Planck Institute for Radio Astronomy in Bonn has discovered an object that orbits the black hole on a very narrow path in only about 70 minutes.

No trace of dark matter halos
Signs of disturbance in the dwarf galaxies of one of Earth's nearest galaxy clusters indicate an alternative gravity theory According to the standard model of cosmology, the vast majority of galaxies are surrounded by a halo of dark matter particles. This halo is invisible, but its mass exerts a strong gravitational pull on galaxies in the vicinity.
