An international team of astronomers has revealed mysterious star formation at the far edge of the galaxy M83. The research used several instruments, including the Atacama Large Millimeter/submillimeter Array (ALMA), the Karl G. Jansky Very Large Array (VLA) and the Green Bank Telescope (GBT) from NRAO, along with the National Astronomical Observatory of Japan’s (NAOJ) Subaru Telescope and the NASA Galaxy Evolution Explorer (GALEX). Read here the ALMA press release.

From left to right: optical image from CTIO, ultraviolet image from GALEX, HI 21cm image from VLA and GBT, and CO(3-2) image from ALMA. In this last image, the star-forming “hearts” of molecular clouds, circled with white, are shown. Credit: J. Koda et al.
