Maximizing the scientific accessibility and impact of astronomical data

Barbara A. Mikulski Archive for Space Telescopes Logo

Maximizing the scientific accessibility & productivity of astronomical data.

The Mikulski Archive for Space Telescopes is an astronomical data archive focused on the optical, ultraviolet, and near-infrared. MAST hosts data from over a dozen missions like Webb, Hubble, TESS, Kepler, and in the future Roman.

Search Tools

MAST Portal

Search multiple collections of astronomical data-sets from one place—images, spectra, catalogs, timeseries, publication records and more

MAST Search

The MAST Search Form is our modernized multi-mission search tool. Try out the new Hubble Search and check back as more missions are added.

Virtual Observatory

The Virtual Observatory (VO) seamlessly incorporates astronomical data from active missions, archives, and other institutional resources worldwide

exo.MAST

Search by exoplanet to find data, parameters, visualizations, and MAST holdings from Kepler, K2, Hubble, TESS and JWST. Easily find the data taken during the transit, interact with folded light curves, and view or download published spectroscopy

Mission Specific Search Forms

Data search forms by individual missions

MAST CasJobs

Run SQL queries on MAST catalogs and tables. Long and complex queries are supported, and users can store the output in a user database

z.MAST

Search for extragalactic observations and catalog data from MAST high-level science products (HLSP). Download results for further analysis or quickly view detailed information by individual galaxy—aggregated data, image cutouts, observed SEDs, and observations

MAST User Documentation

Read documentation on many MAST services, including the Portal, the Modernized MAST Search, HLSPs and more.

Catalogs

Link to
Pan-STARRS Catalog Search The Panoramic Survey Telescope & Rapid Response System (Pan-STARRS or PS1) is a wide-field imaging facility developed at the University of Hawaii's Institute for Astronomy for a variety of scientific studies from the nearby to the very distant Universe. The PS1 catalog allows searches for the mean measurements and the deeper stacked measurements from images combining all the epochs
Link to
Hubble Source Catalog Search The Hubble Source Catalog (HSC) is designed to optimize science from the Hubble Space Telescope by combining the tens of thousands of visit-based source lists in the Hubble Legacy Archive (HLA) into a single master catalog
Link to
Exoplanet Atmosphere Observability Table This table is intended for selecting targets when planning observations of exoplanet atmospheres through transmission and emission. The SNR values, based on observed star and planet parameters, provide guidelines for different wavebands and techniques to allow users to determine those exoplanets most amenable to atmospheric characterization

APIs

Link to
Astroquery A streamlined interface for Python users to access data in MAST. Replicates most functions of the MAST Portal web interface. Access MAST queries using the same function conventions and return types available for all Astroquery services. Integrate easily with Astropy functionality and other Python analysis tools.
Link to
Webservice Programmatic access to MAST data through HTTPS requests. The most direct way to programmatically access data in MAST, it is language agnostic, requiring only the ability to send/receive HTTPS requests.
Link to
Classic Search MAST using HTTP GET requests. The results can be returned in a variety of formats including HTML, VOTable XML format, Excel spreadsheet, and comma-separated values, which can simplify ingesting results into user-written programs.
