Using the James Webb Space Telescope (JWST), an international team of astronomers has observed the galaxy cluster PLCK G165.7+67.0. The observational campaign resulted in the detection of a new Type I supernova. The finding ...
The first stars illuminated the universe during the Cosmic Dawn and put an end to the cosmic "dark ages" that followed the Big Bang. However, the distribution of their mass is one of the great unsolved mysteries of the cosmos.
