Physicists explain how the type of aurora is formed on Mars

Researchers led by the University of Iowa have learned how a type of aurora borealis forms on Mars. In a new study, physicists report a separate aurora formation through the interaction of the solar wind and crust in Mars’ southern hemisphere. Credit: CU/LASP. Physicists led by the University of Iowa have learned how a type … Read more

SGR J1935 + 2154 magnetic star eruptions examined in detail

Time evolution of blackbody temperature (top), radius (middle) and observed flux (bottom) for SGR J1935 between April 27, 2020 and November 20, 2020. Credit: Borghese et al., 2022. European astronomers have conducted a detailed, long-term X-ray observation campaign of a magnetar known as SGR J1935 + 2154, since it entered its active phase, and experienced … Read more

Physicists are shedding new light on an ancient quantum optics problem with collective behaviour

Credit: Gerd Altman from Pixabay When atoms interact with each other, they act as a whole and not as individual entities. This can lead to simultaneous responses to inputs, a phenomenon that, if properly understood and controlled, could be useful for developing light sources, building sensors that can take ultra-precise measurements, and understanding dissipation in … Read more

Insights for better characterization of nuclear physics and the harsh environments of cosmic explosions

An illustration of a conventional modern nova shows a bright white dwarf star near the center accumulating fuel in an orange disk of its neighboring main-sequence star (highlighted in bright orange). Credit: NASA/JPL-Caltech Michigan State researchers helped peer inside a new supernova – a type of astrophysical nuclear explosion – without leaving Earth. These stellar … Read more

Building a better black hole with supercomputer simulation

Astronomers have used a potentially unlikely tool to understand what they saw in their first historic image of the Milky Way’s supermassive black hole: a library of computer simulations that simulate a black hole with millions of variations. photo shoot Black holeLike Sagittarius A* In the center of our galaxy, with event horizon telescope (EHT) … Read more
