An international team of astronomers has inspected a tidal disruption event (TDE) known as AT2020opy using various radio telescopes. Results of the study, published August 30 on the arXiv pre-print server, could shed more ...
The universe is littered with galaxy clusters—huge structures piled up at the intersections of the cosmic web. A single cluster can span millions of light-years across and be made up of hundreds, or even thousands, of galaxies.
