An international team of astronomers used ALMA to capture high-resolution images of eight protoplanetary disks in the Sigma Orionis cluster, which is irradiated by intense ultraviolet light from a massive nearby star. To their surprise, they found evidence of gaps and rings in most of the disks—structures commonly associated with the formation of giant planets, like Jupiter.
The Atacama Large Millimeter/submillimeter Array (ALMA) is thrilled to announce that a record-breaking total of 4,250 hours of science-quality data were successfully collected on the 12-m Array during Cycle 10.
The Atacama Large Millimeter/submillimeter Array (ALMA), one of the largest and most sensitive telescopes of its kind in the world, received a visit from United Nations (UN) Secretary-General António Guterres, who had the opportunity to learn about how ALMA’s high-tech systems capture and combine signals from the cosmos.
An international team of astronomers led by Jessica Speedie, Department of Physics & Astronomy Ph.D. candidate at the University of Victoria (Canada), observed the well-characterized protoplanetary disk around AB Aurigae and found observational evidence that matches the alternative “top-down” theoretical sequence of planet formation.
