An unusual supernova studied by multiple telescopes, including the SOAR telescope and other telescopes at the National Science Foundation’s (NSF) Cerro Tololo Inter-American Observatory (CTIO) and NSF’s Kitt Peak National Observatory (KPNO), is thought to herald the birth of a new black hole or neutron star, caught at the exact moment of its creation. Observations made with facilities ranging from X-rays to optical and radio wavelengths were used to understand this remarkable event. These multi-messenger observations give astronomers a rare glimpse into the physics at play during the creation of a black hole or neutron star.
