Calcium-rich supernova examined with x-rays for first time
X-ray images give unprecedented view of extremely rare type of supernova. New information suggests that these supernovae start as compact stars that lose mass at the end of life. Calcium-rich supernovae are responsible for up to half the calcium in the entire universe. SN 2019ehk has the richest calcium emission of all known transients.
