A team of researchers, led by Grzegorz Pietrzyński from Universidad de Concepción, have measured the mass of a very large and bright star with high accuracy, providing new insight into distances in the universe.
Astronomers of the European Southern Observatory were able to take a new photograph of the star WR 22, known for its unusual brilliance, allowing it to be seen from Earth by the naked eye in spite of being over 5,000 light years away from our planet.
According to the director of Astronomy of the Universidad de Chile, the country occupies a privileged position in this sphere thanks to the institutional environment and physical conditions that have made it possible to install modern scientific complexes.
Using modern equipment at the Cerro Tololo observatory, experts managed to detect a supernova, which they continue to analyze. Their conclusions will be published in an article in the Astrophysical Journal.
