NSF Award Helps Fund a Fast New Transient Survey: the Zwicky Transient FacilityRead MoreOctober 17, 2014 • News Release
Thanks to a $9 million grant from the National Science Foundation and matching funds from the Zwicky Transient Facility (ZTF) collaboration, a new camera is being built at Caltech's Palomar Observatory that will be able to survey the entire Northern Hemisphere sky in a single night.
Supernova Caught in the Act by Palomar Transient FactoryRead MoreMay 21, 2014 • News Release
Supernovae—stellar explosions—are incredibly energetic, dynamic events. It is easy to imagine that they are uncommon, but the universe is a big place and supernovae are actually fairly routine. The problem with observing supernovae is knowing just when and where one is occurring and being able to point a world-class telescope at it in the hours immediately afterward, when precious data about the supernova's progenitor star is available. Fortunately the intermediate Palomar Transient Factory (iPTF) operated by Caltech scans the sky constantly in search of dramatic astrophysical events. In 2013, it caught a star in the act of exploding.
