A deadly asteroidA new Phys.org report released on February 25 could have been the plot of 2021's "Don't Look Up," a Netflix original about a potentially deadly asteroid that threatens to strike Earth. However, the good news is it was simply a close call.According to the website, the first observations of an asteroid called...
Scientists from the Institute of High Energy Physics of the Chinese Academy of Sciences analyzed the validity of the relativity theory with the highest possible accuracy in a study entitled "Exploring Lorentz Invariance Violation from Ultrahigh-Energy γRays Observed by LHAASO," which was published in the most recent issue of Physical Review Letters.According to Einstein's...
Information about a quantum state is split into three information contents (i.e., information gain, disturbance, and reversibility). Credit: Hong et al.Scientists at the Korea Institute of Science and Technology (KIST) have attempted to capture the interaction between different kinds of information that are essential while gathering quantum measurements, specifically information gain, disturbance, and reversibility. Their paper, released...
Arp 282. (ESA/Hubble & NASA, J. Dalcanton, Dark Energy Survey, DOE, FNAL/DECam, CTIO/NOIRLab/NSF/AURA, SDSS, J. Schmidt)The recurring interaction between two galaxies 320 million light-years away has been recorded in a spectacular Hubble picture.They are collectively named Arp 282 in Halton Arp's Atlas of Peculiar Galaxies. They feature a large barred spiral galaxy called NGC 169, approximately 140,000 light-years across, and a considerably...

Re-exploring a renowned meteoriteGround braking Atomic Force Microscopy (AFM) analysis is being used to better explore the chemical diversity of the renowned Murchison meteorite that exploded over Australia in 1969. The desired outcome of this procedure might result in the discovery of new particles in meteorites and samples from space.Preliminary analysis of the Murchison...
