Using the Atacama Large Millimeter/Submillimeter Array (ALMA), an international team of astronomers has observed a supernova remnant known as LHA 120-N49. Results of the observational campaign, published November 3 on the ...
Astronomers have found the youngest still-forming solar system yet seen, an infant star surrounded by a swirling disk of dust and gas more than 450 light-years from Earth in the constellation Taurus.

Using the Submillimeter Array (SMA), astronomers have conducted a molecular line study of the protoplanetary disk Oph-IRS 67, uncovering essential information about its chemical structure. Results of this study were presented ...
A new discovery is shedding light on how fluorine—an element found in bones and teeth as fluoride—is forged in the universe. Using the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern ...
