The new survey—known as the ALMA CMZ Exploration Survey (ACES)—maps more than 650 light-years across the Central Molecular Zone, the extreme environment that surrounds our galaxy’s supermassive black hole.

New Event Horizon Telescope Results Trace M87 Jet Back to Its Black Hole
A new study connects the black hole’s famous ring of light to a compact region that marks the likely base of the jet, bringing scientists closer to understanding how black holes power some of the brightest beacons in the universe.
Magnetic Superhighways Discovered in a Starburst Galaxy’s Winds
Using the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers has mapped a magnetic highway driving a powerful galactic wind into the nearby galaxy merger of Arp 220, revealing for the first time that its fast, molecular outflows are strongly magnetized and likely helping to drive metals, dust, and cosmic rays into the space around the galaxy.
ALMA Reveals Teenage Years of New Worlds
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS), using the Atacama Large Millimeter/submillimeter Array (ALMA), has produced the sharpest images ever of 24 debris disks, the dusty belts left after planets finish forming. These disks are the cosmic equivalent of the teenage years for planetary systems—somewhat more mature than newborn, planet-forming disks, but not yet settled into adulthood.
