World's First Milky Way Simulation Models 100 Billion Stars With Record-Breaking Speed Groundbreaking Milky Way Simulation Achieved Researchers have achieved the world's first Milky Way simulation capable of accurately modelling more than 100 billion individual stars across a span of 10,000 years. This breakthrough, driven by a fusion of artificial intelligence and numerical techniques, delivers a model 100 times more detailed than previous efforts — and completes the task over 100 times faster. * ➤  Latest Space Science News The study, published in the Proceedings of the International Conference for High Performance Computing, Networking, Storage and Analysis, demonstrates a major breakthrough at the nexus of astrophysics, supercomputing, and AI. Its methodology may also be harnessed to model broader systems such as climate trends and meteorological shifts. Challenges of Simulating the Milky Way Astrophysicists have long sought to simulate the Milky Way at the level of individ...

TeV Halos Around Middle-Aged Pulsars May Be Universal, Study Reveals Introduction: Pulsars and Their Mysterious Radiation Rapidly rotating neutron stars known as pulsars give off periodic radio wave emissions and streams of magnetic radiation, some of which are observable from Earth. These stellar remnants originate from the explosive deaths of massive stars. Discovery of TeV Halos Around Middle-Aged Pulsars Astronomers have recently detected expansive regions emitting gamma rays at TeV energies surrounding middle-aged between 100,000 and one million years. Termed TeV halos, these zones are markedly larger than the pulsars' own wind nebulae — clouds formed by the rotation and magnetic fields of the neutrons stars. Scientific Mystery: What Causes TeV Halos? The existence of TeV halos encircling some middle-aged pulsars is now well-substantiated, but the underlying processes responsible for their emergence are still not fully understood. It also remains an open question whether these...
