For the first time, astronomers using ALMA have witnessed 3D motions of gas in a planet-forming disk. At three locations in the disk around a young star called HD 163296, gas is flowing like a waterfall into gaps that are most likely caused by planets in formation.

At the center of a galaxy called NGC 1068, a supermassive black hole hides within a thick doughnut-shaped cloud of dust and gas. When astronomers used ALMA to study this cloud in more detail, they made an unexpected discovery that could explain why supermassive black holes grew so rapidly in the early Universe.

The first ever Canadian-led Atacama Large Millimeter/submillimeter Array (ALMA) Large Program has been approved for cycle 7. Dr. Brown and his colleagues will use the Atacama Compact Array (ACA) to study the influence of galaxy environment on star formation in the Virgo Cluster.

New radio wave images made with the Atacama Large Millimeter/submillimeter Array (ALMA) provide a unique view of Jupiter’s atmosphere down to fifty kilometers below the planet’s visible cloud deck.

Using the both ALMA and the VLT, astronomers have imaged the cold, rock-strewn rings encircling the planet Uranus. Rather than observing the reflected sunlight from these rings, ALMA and the VLT imaged the millimeter and mid-infrared “glow” naturally emitted by the frigidly cold particles of the rings themselves.

New ALMA observations reveal a never-before-seen disk of cool, interstellar gas wrapped around the supermassive black hole at the center of the Milky Way.

For decades astronomers have dreamed of seeing a black hole. That dream may soon become a reality.

Using the EHT, with ALMA as its most sensitive component, astronomers have captured the first direct visual evidence of a black hole: an image of the supermassive black hole at the center of Messier 87 (M87), a giant elliptical galaxy 55 million light-years from Earth.

Using ALMA, astronomers have observed the formation and mutually entwined motions of a massive binary star system.

ALMA discovered ordinary table salt in a not-so-ordinary location: 1,500 light-years from Earth in the disk surrounding a massive young star.
