US EditionLargest-Ever ALMA Image Reveals Milky Way's Hidden Core
The ALMA Central Molecular Zone Exploration Survey revealed a complex 650-light-year region with diverse molecules and star formation near the Galactic center, scientists said.
- On Feb. 25, the Atacama Large Millimeter/submillimeter Array released its largest-ever image, capturing cold cosmic gases over more than 650 light-years and published in Monthly Notices of the Royal Astronomical Society.
- Survey leader Steve Longmore, ACES survey leader , said studying star formation in the Central Molecular Zone helps explain how galaxies grew and evolved, as it is an extreme, nearby galactic nucleus surrounding Sagittarius A*.
- Using many pointings, the team stitched many smaller ALMA observations into a mosaic, employing ALMA's 66 radio antennas to map cold gas and dust at the galaxy's center.
- The ACES team reported determining the molecular gas's chemical composition, detecting dozens of molecular species, and said the image should help scientists study star formation near the central black hole.
- The team notes the CMZ shares features with early-universe galaxies, hosting massive stars that end in supernovae and hypernovae, surprising ALMA astronomer Katharina Immer.

The European Southern Observatory (ESO) published this Wednesday the largest and most detailed image ever obtained from the center of the Milky Way, captured by the ALMA antenna network in the Atacama desert (Chile).The map shows, with an unprecedented level of detail, more than 650 light years of cold and dense cosmic gas swirling around the central supermassive black hole.Continue reading...
A spectacular new image of the Milky Way amazes astronomers and space fans alike. The central region of our galaxy, which is invisible to the naked eye, is now revealed in unprecedented detail: density of gas filaments flowing through the galactic core like colorful currents, reveal the birthplaces of stars. The image is taken by the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, a composite of 66 state-of-the-art radio telescopes…
