Title:  Observing stars as they explode: toward a live movie of the sky

Abstract: The study of the transient night sky offers an opportunity to tackle some long-standing open questions in 

astrophysics, such as: how and why do stars explode? when do such explosions leave behind neutrons stars

or black holes? and what is the origin of the elements? I will show that observations of cosmic explosions, and

in particular observations obtained as soon as possible after the explosion, provide new clues about these 

open questions. I will review the progress made in this field in recent years, present recent results, mostly based 

on our work with the Zwicky Transient Facility (ZTF), and present prospects for additional discoveries from 

new ground- and space-based surveys.
