code: I41) is a wide-field sky astronomical survey using a new camera attached to the Samuel Oschin Telescope at Palomar Observatory in San Diego County, California, United States.

[1] Observing in visible and infrared wavelengths,[2] the Zwicky Transient Facility is designed to detect transient objects that rapidly change in brightness, for example supernovae, gamma ray bursts, and collision between two neutron stars, and moving objects like comets and asteroids.

The new camera is made of 16 CCDs of 6144×6160 pixels each, enabling each exposure to cover an area of 47 square degrees.

[3][4] The amount of data produced by ZTF is expected to be ten times larger than its predecessor, the Intermediate Palomar Transient Factory.

[6][7][8] The first confirmed findings from the ZTF project were reported on 7 February 2018,[9] with the discovery of 2018 CL, a small near-Earth asteroid.
