About PHANGS HST & JWST
PHANGS (Physics at High Angular resolution in Nearby GalaxieS) has conducted the principal ALMA Large Program for nearby galaxies, and has obtained CO (2-1) maps for a complete sample of 74 spiral galaxies. HST and JWST imaging spanning from the near-UV to 21 microns for all 74 galaxies is being obtained through five PHANGS programs:
- HST Treasury (2019-21 PI: JC Lee)
- JWST Treasury (2022-24 PI: JC Lee)
- HST H-alpha Treasury (2023-24 PI: R Chandar)
- HST2 Treasury (2023-24 PI: D Thilker)
- JWST2 Treasury (2023-24 PI: A Leroy)
- HST H-alpha (2024 PI: F Belfiore)
The combination of these surveys provide the first dataset to enable the multi-phase, multi-scale study of star formation across spiral galaxies in the local universe, from star clusters and molecular clouds to galactic disks.
PHANGS-HST Catalogue paper accepted for publication at ApJS
The second paper in a series presenting the catalogs and properties of the largest sample to-date of ∼100,000 star clusters and compact associations, in 38 spiral galaxies observed by the PHANGS-HST Treasury survey has been accepted for publication in The Astrophysical Journal Supplement Series.
U.S. Postal Service issues stamp with a PHANGS image on January 21st 2025
NEW !
The U.S. Postal Service celebrates our continued exploration of deep space with a captivating new Priority Mail stamp. Like a sprawling celestial nautilus located 32 million light-years from Earth, spiral galaxy NGC 628 provides clues to how star formation occurs, and galaxies evolve. Captured in unprecedented detail by NASA’s James Webb Space Telescope (JWST) in 2022, this and other images of spiral galaxies help scientists investigate the star formation cycle in galaxies on an unprecedented new scale and provide valuable new clues to the origins of our universe.

Funding shortfall for Hubble impacts PHANGS science
NEW !
Due to a severe reduction in NASA funding for HST programs, we regret to announce that high level image and catalog products will not be released from PHANGS-HST2 (GO-17502), which is supported at a per-orbit-level ~4 times lower than the original PHANGS-HST Treasury program (GO-15654). Funded PHANGS-HST2 activities will focus on science analysis of star clusters, and will exclude the study of multi-scale associations and HII regions that was described in the approved proposal.

PHANGS-JWST ApJL First Results Special Issue
PHANGS JWST First Results JWST is revolutionizing fields across astrophysics, and chief among them is the study of the earliest stages of star formation and the dusty interstellar medium (ISM). On February 2023, a special issue of the Astrophysical Journal Letters was printed to celebrate the first results.
JWST Cycle 1 Treasury Program
A JWST Cycle 1 Treasury Program to image 19/38 galaxies with full coverage by ALMA/MUSE/HST with NIRCAM and MIRI has been approved. A January 2022 article entitled Capturing All That Glitters in Galaxies With NASA’s Webb provides an overview of the PHANGS-JWST survey understandable to the public.
PHANGS-CAT Data Release 1 (2022)
PHANGS-CAT DR1 at MAST provides catalogs for compact clusters and a separate set of catalogs for multi-scale associations for five galaxies: NGC 1433, NGC 1566, NGC 1559, NGC 3351, and NGC 3627. Please see the PHANGS-CAT site at MAST for more information.
PHANGS-HST Data Releases 1 & 2 (2021)
PHANGS-HST DR1 & DR2 at MAST provides imaging for all 38 galaxies in the sample, as well as visualization tools, and neural network models for star cluster morphological classification. Please see the PHANGS HST site at MAST for more information.
