Earth-Like Rocky Planets May Be Far More Common Across the Galaxy, Scientists Say Rocky planets similar to Earth could be far more widespread than astronomers once believed, opening new possibilities in the search for life beyond our solar system. New findings suggest a powerful cosmic process may have played a critical role in shaping dry, habitable worlds throughout the Milky Way. For more space and planetary science updates, visit FSNews365 Supernova Shockwaves May Have Shaped Earth-Like Worlds Rocky planets similar to Earth may be far more widespread than once believed, according to new research published in Science Advances . The study suggests that, during the formation of our solar system, a nearby supernova flooded the region with cosmic rays carrying radioactive elements capable of creating dry, rocky worlds. If correct, this process may be common throughout the galaxy. How Earth-Like Planet Formed in a Radioactive Environment Earth-like planets are thought to form from plane...

LHAASO Discovers the True Origin of the Cosmic Ray "Knee" in the Milky Way Introduction  —  A 70-Year Astrophysics Mystery Solved On 16 November, the Large High Altitude Air Shower Observatory (LHAASO) announced landmark results that resolve a long-standing enigma in astrophysics: the mysterious knee-like dip in the cosmic ray energy spectrum occurring beyond 3 PeV. The origin of the "knee" has puzzled scientists for almost 70 years. It was long thought to mark the acceleration limit of cosmic-ray sources and signal a shift between two power-law energy distributions. Now, two new papers — appearing in National Science Review and Science Bulletin — show that micro-quasars powered by black hole accretion are potent particle accelerators within the Milky Way and likely creators of the "knee." The work was carried out by teams from the Institute of High Energy Physics, Chinese Academy of Sciences (CAS), Nanjing University, the University of Science and Techn...
