A massive stellar burst, before the supernova
In data from the Palomar Transient Factory housed at Lawrence Berkeley National Laboratory's National Energy Research Scientific Computing Center, astronomers have found the first causal evidence that massive stars shed huge amounts of material in a "penultimate outburst" before they finally detonate as Type IIn supernovae.
