Which instrument combination was used to map the water and heavy water in Comet 12P/Pons-Brooks (the 'Devil Comet')?
Answer
ALMA and NASA’s Infrared Telescope Facility (IRTF)
An international team used the sensitivity of the Atacama Large Millimeter/submillimeter Array (ALMA) combined with NASA’s Infrared Telescope Facility (IRTF) to obtain detailed spatial mapping of Comet 12P/Pons-Brooks.
