Ultraviolet light gives astronomers new clues on mysterious stellar eruptions


This is where the story gets hot

In December 2019, astronomers at the Zwicky Transient Facility (ZTF) in California spotted a supernova they dubbed SN2019yvq. Analysis of the data revealed this was a type Ia [one A] supernova, a fairly-common type of explosion for white dwarf stars. Taking place roughly 140 million light years from Earth, this event was seen near the tail of the constellation Draco.
