Neutron stars have the strongest magnetic fields in the universe, and the only way to measure their surface magnetic field directly is to observe the cyclotron absorption lines in their X-ray energy spectra. The Insight-HXMT team has recently discovered a cyclotron absorption line with an energy of 146 keV in the neutron star X-ray binary ...
Russia’s invasion of Ukraine has brought the threat of nuclear warfare to the forefront. But how would modern nuclear detonations impact the world today? A new study provides stark information on the global impact of nuclear war. The study’s lead author LSU Department of Oceanography & Coastal Sciences Assistant Professor Cheryl Harrison and coauthors ran multiple computer simulations ...
Although the Earth has long been studied in detail, some fundamental questions have still to be answered. One of them concerns the formation of our planet, about whose beginnings researchers are still unclear. An international research team led by ETH Zurich and the National Centre of Competence in Research PlanetS is now proposing a new ...
Scientists have found evidence that the Earth’s inner core oscillates, contradicting previously accepted models that suggested it consistently rotates at a faster rate than the planet’s surface. Their study, published in Science Advances, shows that the inner core changed direction in the six-year period from 1969–74, according to the analysis of seismic data. The scientists say their ...
Jules Verne could not even dream of this: A research team from the University of Bayreuth, together with international partners, has pushed the boundaries of high-pressure and high-temperature research into cosmic dimensions. For the first time, they have succeeded in generating and simultaneously analyzing materials under compression pressures of more than one terapascal (1,000 gigapascals). ...
Physicists know about the huge chasm between quantum physics and the theory of gravity. However, in recent decades, theoretical physics has provided some plausible conjecture to bridge this gap and to describe the behavior of complex quantum many-body systems, for example, black holes and wormholes in the universe. Now, a theory group at Freie Universität ...
A new study uses data on lead levels in the livers of thousands of dead birds of prey to calculate the impact of lead poisoning on population size. Poisoning caused by preying on or scavenging animals shot by hunters using lead ammunition has left the populations of many birds of prey far smaller than they ...
The rapid development of fauna 540 million years ago has permanently changed the Earth — far into its deep mantle. A team led by ETH researcher Andrea Giuliani found traces of this development in rocks from this deep mantle layer. It is easy to see that the processes in the Earth’s interior influence what happens ...
Rochester astrophysicist Adam Frank discusses why cognitive activity operating on a planetary scale is necessary to tackle global issues such as climate change. The collective activity of life — all of the microbes, plants, and animals — has changed planet Earth. Take, for example, plants. Plants “invented” a way of undergoing photosynthesis to enhance their ...
Primordial black holes created in the first instants after the Big Bang — tiny ones smaller than the head of a pin and supermassive ones covering billions of miles — may account for all of the dark matter in the universe. That’s the implication of a new model of the early universe created by astrophysicists ...
