A new supernova in the Pinwheel galaxy has been imaged by the Gemini North Telescope after it operated again after repairs. You can read the details here:

In the meantime, Subaru data from 2015 has shown strong evidence of a pair-instability supernova from the very early universe. These are stars/supernovae that are well understood in theory but have never been observed before. They lack heavy elements as the early universe contained only the lightest of elements, so these are the stars that started the process of creating heavier elements where we all come from.
