The Big Picture
GROWTH is an international scientific collaborative project in astronomy studying the physics of fast-changing events in the cosmos like supernovae, neutron stars or black hole mergers, and near-earth asteroids.

Who is involved
GROWTH is led by Caltech and has partnered with fifteen universities and research institutions - six in the USA and nine spread across the world in India, Sweden, Taiwan, Japan, Israel, Germany, UK and Australia.
Read moreWhat we want to do
We want to continuously gather data on cosmic transient events in the first ~24 hours after detection to build a more complete picture and better understanding of the physical processes that govern their evolution.
Read moreHow we will do it
We jointly operate 18 observatories in the northern hemisphere. As the earth rotates and daylight creeps in at one of our locations, we switch observations to our facilities which still enjoy nighttime.
Read moreWhy it is important
Light curves of transient events (change of brightness over time), coupled with data about their spectrum can tell us how heavy elements are formed, what events generate gravitational waves, and much more.
Read moreWe are supported by
GROWTH is funded by the NSF under the Partnership for International Research and Education (PIRE) program with national funding available to partners in Taiwan, Japan and India.
