Extensive catalog of exploding stars

The largest data release of relatively nearby supernovae (colossal explosions of stars) contains three years of data from the University of Hawaii's Pan-STARRS telescope atop Haleakal on Maui.

The Young Supernova Experiment (YSE) surveyed more than 1,500 square degrees of sky every three days and discovered thousands of new cosmic explosions and other astrophysical transients, dozens of them just days or hours after exploding.

It is also the first to extensively use the multi-color imaging to classify the supernova and estimate their distances.
