Peptides on Interstellar Ice
Peptides are organic compounds that play a crucial role in many biological processes, for example, as enzymes. A research team led by Dr Serge Krasnokutski from the Astrophysics Laboratory at the Max Planck Institute for Astronomy at the University of Jena had already demonstrated that simple peptides can form on cosmic dust particles.

Magnetic fields spiral around the mass monster Sagittarius A* and form up for a restart The Event Horizon Telescope, a network of individual radio telescopes located all'over the world, has once again observed the centre of our galaxy, the Milky Way. Using the polarised part of the radio light, the researchers discovered strong magnetic fields that spiral out from the edge of the supermassive black hole Sagittarius A*.

Searching for clues in a fly-by
The BepiColombo space probe measures carbon ions escaping from the atmosphere of Venus and thus helps to decipher the special development of Venus During its flyby of Venus, the European-Japanese space probe Bepi Colombo for the first time found carbon ions escaping from the planet's atmosphere into space in a previously unexplored region on the night side of the planet.

For future space missions: Scientists develop hood to measure brain activity in space
Prof. Patrique Fiedler and his team at the Institute of Biomedical Engineering and Informatics (BMTI) at TU Ilmenau are working on an EEG system suitable for use in space. It is intended to accompany astronauts on long-term missions in order to recognize and counteract limitations in their performance in good time.

Mysterious object in the gap
Mysterious object in the gap
On May 29, 2023, the LIGO Livingston detector observed a mysterious signal, called GW230529. It originated from the merger of a neutron star with an unknown compact object, most likely an unusually light-weight black hole. With a mass of only a few times that of our Sun, the object falls into the "lower mass gap" between the heaviest neutron stars and the lightest black holes.

James Webb Space Telescope: Fascinating Images Show Nearby Spiral Galaxies
James Webb Space Telescope: Fascinating Images Show Nearby Spiral Galaxies
Heidelberg University astrophysicist vital contributor to preparation and study of new data Fascinating new images from NASA's James Webb Space Telescope show the structure of 19 nearby spiral galaxies. They were acquired with infrared light and provide a detailed view of the distribution of stars and the material from which they form.

Bacteria beyond Earth?
Bacteria beyond Earth?
Signs of life detectable in single ice grains emitted from moons orbiting Saturn and Jupiter The ice-encrusted oceans of some of the moons orbiting Saturn and Jupiter are prime candidates in the search for extraterrestrial life. A new lab-based study led by Freie Universität Berlin and the University of Washington, Seattle, shows that individual ice grains ejected from these planetary bodies may contain enough material for instruments headed there this fall to detect signs of life - if such life exists.

Cosmic building blocks of life discovered through the electron microscope
Cosmic building blocks of life discovered through the electron microscope
For the first time without any chemical treatment, a research team analyses extraterrestrial amino acids and other organic compounds in an English meteorite fall Meteorites are fragments of asteroids which find their way to Earth as shooting stars. These cosmic sediments have frozen the primordial soup from which our solar system emerged - preserving it just like a time capsule.

Black hole at the centre of a galaxy in the early universe received less mass influx than expected With the upgraded GRAVITY-instrument at the Very Large Telescope Interferometer of the European Southern Observatory, a team of astronomers led by the Max Planck Institute for Extraterrestrial Physics has determined the mass of a Black Hole in a galaxy only 2 billion years after the Big Bang.

Black Hole Shadow
Black Hole Shadow
One year after the discovery image of the black hole M87*, improved observations of the Event Horizon Telescope (EHT) Collaboration give a better picture showing a persistent black hole shadow. The Event Horizon Telescope (EHT) Collaboration including scientists at Julius-Maximilians-Universität (JMU) Würzburg has released a new image of M87*, the supermassive black hole residing at the heart of the galaxy Messier 87.

Moon rocks with unique dust found
Moon rocks with unique dust found
Research team studies interaction of dust with boulders and discovers potentially anomalous rocks Our Earth's Moon is almost completely covered in dust. Unlike on Earth, this dust is not smoothed by wind and weather, but is sharp-edged and also electrostatically charged. This dust has been studied since the Apollo era at the end of the 1960s.

Mysterious object attracts attention
Mysterious object attracts attention
Data from the MeerKAT radio telescope reveal an object at the boundary between a black hole and a neutron star When astronomers cannot explain something directly, it often becomes really exciting. An international team led by researchers from the Max Planck Institute for Radio Astronomy and with the participation of the Max Planck Institute for Gravitational Physics has now discovered a mysterious tandem that has never been observed before: a system consisting of a neutron star and an object that, at first glance, should not even exist.

Extrasolar worlds between several suns
Extrasolar worlds between several suns
People in ancient times knew five planets: Mercury, Venus, Mars, Jupiter and Saturn, which they considered to be "wandering stars". It was only with the Copernican revolution in the 16th century, the Earth itself also became a planet, orbiting our planet host star - the Sun - just like the previously known and later discovered representatives Uranus and Neptune.

Why weighty stars hold together
Why weighty stars hold together
ALMA Radio observatory observes for the first time how double, triple, quadruple and quintuple star systems form simultaneously in a molecular cloud For humans, the chance of giving birth to multiples is less than two per cent. The situation is different with stars, especially with particularly heavy stars.

Würzburg computer scientists dive down
Researchers at the University of Würzburg have developed a virtual reality (VR) application for training astronauts. It allows the training of various mission scenarios under water. Nowhere can the zero gravity of space be simulated as well as in water - training in large indoor swimming pools is therefore part of the daily routine for astronauts in training.

International research team models the different signatures of a kilonova explosion simultaneously for the first time Neutron stars are the end products of massive stars and gather together a large part of the original stellar mass in a super-dense star with a diameter of only around ten kilometres.

Stellar Birthplaces in the Whirlpool Galaxy
Researchers have charted vast areas of the dense, cold gas of star nurseries in a neighboring galaxy for the first time. An international research team led by the Max Planck Institute for Astronomy (MPIA) and involving the University of Bonn has mapped the cold, dense gas of future star nurseries in one of our neighboring galaxies with an unprecedented degree of detail.

Giant doubts about giant exomoons
Giant doubts about giant exomoons
Discovery of giant exomoons around the planets Kepler-1625b and Kepler-1708b called into question Just as it can be assumed that the stars in our Milky Way are orbited by planets, moons around these exoplanets should not be uncommon. This makes it all the more difficult to detect them. So far, only two of the more than 5300 known exoplanets have been found to have moons.

Cradle of possible Earth-like planets found in harsh environment
Planets like our Earth could form even in the harshest known star-forming environments, drenched by hard UV light from massive stars. That is a main result of analyses of new observations of such an environment with the James Webb Space Telescope. The observations are the first of their kind - before James Webb, this kind of detailed observation had not been possible.

A new possible explanation for the Hubble tension
A new possible explanation for the Hubble tension
Study by the Universities of Bonn and St. Andrews proposes a solution to one of the great mysteries of cosmology The universe is expanding. How fast it does so is described by the so-called Hubble-Lemaitre constant. But there is a dispute about how big this constant actually is: Different measurement methods provide contradictory values.
