The hidden chemistry at the heart of the Milky Way

Key Points:

• Scientists using the ALMA radio telescope array have captured the largest and most detailed image ever of the Milky Way's center, revealing intricate structures of swirling molecular gas and filaments that provide new insights into star formation and galactic dynamics.
• The image is a color-coded mosaic showing different molecules such as carbon monoxide and methanol, each with unique radio frequency fingerprints, helping scientists study the cold, dense gas clouds where stars and planetary systems form.
• A surprising discovery from the data is an unknown compact object dubbed the "millimeter ultra-broad line object" (MUBLO), detected only at millimeter wavelengths, with properties unlike any previously known astronomical object, prompting ongoing investigations.
• The ALMA survey complements observations from the James Webb Space Telescope, which will map the same region in infrared to identify young stars, enhancing understanding of star formation in extreme environments similar to those of the early universe.
• Researchers emphasize the importance of continued funding for space science, warning that cuts to scientific research support could jeopardize the ability to analyze data from major observatories like ALMA and James Webb, hindering future discoveries.
