Terzan 5 star cluster is a copious producer of cosmic rays, because it contains a large population of rapidly rotating, incredibly dense and magnetised millisecond pulsars – which accelerate cosmic rays up to extremely high speeds.
A new image of star cluster RCW 38, an area strewn with young, hot, massive stars, is providing an unprecedented glimpse into a tumultuous region of space located 5,500 light-years from Earth.
An international team of astronomers is releasing the most comprehensive, high-resolution ultraviolet-light survey of nearby star-forming galaxies.
