Astronomers have studied the most powerful gamma-ray burst ever detected, called BOAT, which originated from a supernova in a star 2.4 million light-years away, providing new insights into the structure of jets in such explosions and demonstrating the capabilities of advanced telescopes like LST-1.
Scientists have discovered a naturally occurring particle accelerator near a small black hole called SS 433, shedding light on the mystery of how high-energy cosmic rays reach Earth at nearly the speed of light. This finding provides unprecedented detail into the acceleration of cosmic rays and suggests that particles are accelerated to near the speed of light by encountering an invisible wall, causing energy to build up and propel them into space. The discovery, published in the journal Science, marks a significant step towards understanding the origins of these mysterious cosmic rays.
