An independent determination of the distance to #supernova #SN1987A by means of the #LightEcho AT 2019xis: https://arxiv.org/abs/2305.03456 -> "We obtained distances to SN 1987A in the range from 49.09 ± 2.16 kpc to 59.39 ± 3.27 kpc, depending on the interstellar polarization and extinction corrections, which are consistent with the literature values. This study demonstrates the potential of using light echoes as a tool for distance determination to astrophysical objects in the Milky Way [...]."
