Archives & Data Science

IPAC leverages its expertise in data science and curation to operate three of NASA's six Astrophysics Data Centers: IRSA, the NASA Exoplanet Archive, and NED. IPAC also serves the community by supporting the Keck Observatory Archive, and the ZTF time domain survey. IPAC data science activities seek to develop tools and techniques to facilitate archive exploration and scientific discovery in the era of big data.



IRSA is chartered to curate the science products of NASA's infrared and submillimeter missions. In total, IRSA provides access to more than 100 billion astronomical measurements, including all-sky coverage in 20 bands.

Keck Observatory Archive

The Keck Observatory Archive is a NASA-funded collaboration between NExScI/IPAC and the W. M. Keck Observatory. KOA’s goal is to provide a long-term archive for all observations acquired at the two 10-m telescopes of the W. M. Keck Observatory on Mauna Kea, Hawaii.

NASA Exoplanet Archive

The NASA Exoplanet Archive provides data and tools to support community discovery and characterization of exoplanets and their host stars.

The NASA/IPAC Extragalactic Database (NED) is an information system provided to the astronomical community that facilitates and accelerates multi-wavelength research on objects beyond our Milky Way galaxy. It is designed, developed, maintained and operated at IPAC, under contract with NASA. NED is the longest running project at IPAC, and recently celebrated its 25th anniversary.

Zwicky Transient Facility (ZTF)

The Zwicky Transient Facility (ZTF) is a new time-domain survey that will have first light at Palomar Observatory in Spring 2017. Building on the highly successful legacy of the Palomar Transient Factory (PTF), ZTF will use a new camera with a 47 square degree field of view mounted on the Samuel Oschin 48-inch (1.2m) Schmidt telescope. The new camera (16 elements of 6kx6k CCDs) enables a full scan of the northern visible sky every night. ZTF's extremely wide field and fast readout electronics will enable a survey more than an order of magnitude faster than that of PTF. ZTF will search and catalog rare and exotic transients and its data will drive novel studies of supernovae, variable stars, binaries, AGN, and asteroids.
