An international team of astronomers has performed spectroscopic observations of a nearby Type I superluminous supernova known as SN 2018bsz. The observational campaign sheds more light on the properties of this supernova, suggesting that it showcases aspherical circumstellar material. Results of the study were presented in a paper published February 3 on arXiv.org.
