Mosaic of the 19 spiral galaxies studied by the PHANGS project

The images of 19 spiral galaxies captured by the James Webb Space Telescope have been released as part of the PHANGS (Physics at High Angular resolution in Nearby GalaxieS) project. These are galaxies up to 65 million light-years away that we see face-on, and this allows to better observe the stars inside them, an optimal situation for a project focused on star formation processes. Webb’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) instruments were employed to cover the near and mid-infrared resulting in many new details.
