An article published in "The Astrophysical Journal" reports the results of a study of dust generated by red giant stars towards the end of their lives under conditions similar to those existing in the first galaxies of the universe. A team of researchers led by Claudio Gavetti of the Italian National Institute for Astrophysics and the University of Roma Tre used observations conducted with the James Webb Space Telescope to study the Sextans A dwarf galaxy, where the environment is very metal-poor. Observations of a quality unimaginable in the past allowed to understand how these stars produce cosmic dust in environments similar to those of the early universe.
