Using the new space telescope, international research team under Heidelberg leadership discovers galaxy cluster in formation Using the observations of a distant, very luminous galaxy, an international research team has discovered a cluster of galaxies with the aid of the James Webb Space Telescope (JWST) and, at the same time, one of the densest known areas of galaxy formation in the early Universe.

New findings lay the foundation for the search for dark matter How are galaxies born, and what holds them together? Astronomers assume that dark matter plays an essential role. However, as yet it has not been possible to prove directly that dark matter exists. A research team including Technical University of Munich (TUM) scientists has now measured for the first time the survival rate of antihelium nuclei from the depths of the galaxy - a necessary prerequisite for the indirect search for Dark Matter.

In future it will be possible to incorporate data from deep space telescopes into the underlying atomic models with a high degree of reliability Very hot gas, as found in the sun's corona or in close proximity to black holes, emits very intense x-rays. It reveals the locally prevailing physical conditions, such as temperature and density.

Technically, it would be possible for future space missions to detect DNA, lipids and other bacterial components on icy moons with an ocean beneath the ice in our solar system - assuming these building blocks of life exist beyond Earth. This is the conclusion reached by an international team of scientists including Professor Abel's research group at Leipzig University.

Researchers at Freie Universität Berlin Publish Study in the Journal Astrobiology. In the future, space missions would be at least technically capable of detecting DNA, lipids, and other components of bacteria on ocean moons in our solar system - if such building blocks of life exist outside Earth. This has now been demonstrated in laboratory experiments by an international team led by scientists from the Planetary Science and Remote Sensing Research Group at Freie Universität Berlin.

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.

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.

Quasars, for example, are one of the brightest and most active varieties of galactic centers.

Numerical simulation representing the curvature of spacetime during the merger of the two black holes. When black holes collide in the universe, the clash shakes up space and time: the amount of energy released during the merger is so great that it causes space-time to oscillate, similar to waves on the surface of water.

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.

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.

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.

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.

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.

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 .

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.

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.

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.
