Massive galaxies with extra-large extended "puffy" disks produced stars for longer than their more compact cousins, new modelling reveals.
The complex mechanics determining how galaxies spin, grow, cluster and die have been revealed following the release of all the data gathered during a massive seven-year Australian-led astronomy research project.
Findings suggest the first galaxies in the universe were more massive than previously thought.
The study of warm dense matter helps us understand what is going on inside giant planets, brown dwarfs, and neutron stars. However, this state of matter does not occur naturally on Earth. It can be produced artificially in the lab using large X-ray experiments. Models are essential to evaluate these experiments. Scientists from CASUS at HZDR have now developed a method to evaluate such experiments more effectively and faster than before.
Researchers discovered that light pollution is linked to preterm birth, a shortened gestational length, and reduced birth weight. babies born too early have higher rates of death and disability. In 2018, preterm birth and low birth weight accounted for roughly 17% of infant deaths (deaths before one year of age). Researchers hope this spawns policy discussion around minimizing light pollution.
NASA's Roman Space Telescope will conduct a microlensing survey to reveal worlds that are similar to the planets in our solar system. Now, a new study shows that the same survey will also unveil more extreme planets and planet-like bodies in the heart of the galaxy, thanks to their gravitational tug on the stars they orbit.
The CHEOPS space telescope detects six planets orbiting the star TOI-178. Five of the planets are in a harmonic rhythm despite very different compositions - a novelty. CHEOPS is a joint mission by the European Space Agency (ESA) and Switzerland, under the aegis of the University of Bern in collaboration with the University of Geneva.
It was previously thought that collisions between galaxies would necessarily add to the activity of the massive black holes at their centers. However, researchers have performed the most accurate simulations of a range of collision scenarios and have found that some collisions can reduce the activity of their central black holes. The reason is that certain head-on collisions may in fact clear the galactic nuclei of the matter which would otherwise fuel the black holes contained within.
in a new study published in The Astrophysical Journal, researchers combined observations from a telescope in New Mexico, the United States, with satellites located near Earth to identify a link between magnetic waves in the chromosphere and areas of abundant ionised particles in the hot outer atmosphere.
An international team of researchers from the University of Oxford, LMU Munich, ETH Zurich, BGI Bayreuth, and the University of Zurich discovered that a two-step formation process of the early Solar System can explain the chronology and split in volatile and isotope content of the inner and outer Solar System.
