HATPI

A new lens on the universe

High-precision imaging of the full night sky

The HATPI Project

Learn More

In a single 45 second exposure, the HATPI instrument observes the full night sky, in all directions, from the zenith down to an elevation angle of 35 degrees, at a spatial resolution of 20 arcseconds per pixel. The key science aim of HATPI is to explore the variable sky, including studying astrophysical transient events (cosmic explosions), transiting exoplanets, variable stars, and moving objects (near‑Earth asteroids). HATPI is located at Las Campanas Observatory in the Chilean Andes
