Zwicky Transient Facility nabs several supernovae a night
The results are rolling in from Caltech’s newest state-of-the-art sky-surveying camera, which began operations at the Palomar Observatory in March 2018. Called the Zwicky Transient Facility, or ZTF, the new instrument has so far discovered 50 small near-Earth asteroids and more than 1,100 supernovae, and it has observed more than 1 billion stars in the Milky Way galaxy. One of the near-Earth asteroids discovered by ZTF, called 2019 AQ3, has an orbital period of just 165 days, the shortest known “year” for any asteroid.
