Global Relay of Observatories Watching Transients Happen (GROWTH) is a 5 year project, funded by the National Science Foundation to advance our understanding of cosmic transient events - supernovae, white dwarf detonations, merging neutron stars, fast moving near-earth asteroids, gamma-ray bursts and more. Led by Caltech, GROWTH partner institutions from around the world have created a network of telescopes to continuously observe the transient sky unbeaten by sunrise. Such extended observations in the first 24 hours after a cosmic transient is detected help us to localize the primary sources of gravitational waves, identify the long sought cosmic location of heavy element production (see Caltech-led LIGO and astronomy teams strike gold) , track and analyze small near-earth asteroids and much more.
