An artist’s impression of Orion Source I, a young, massive star about 1,500 light-years away. The blue region -- about 1/3 the way out from the center of the disk -- represents the region where ALMA detected the millimeter-wavelength ‘glow’ from the salts. Image credit: NRAO / AUI / NSF / S.

ALMA Detects Salts around Young Star

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected the chemical fingerprints of sodium chloride (NaCl), potassium...

Stellar explosions are often associated with supernovae, the powerful and catastrophic deaths of stars. But new ALMA observations of the Orion Nebula complex provide insights into explosions at the other end of the stellar life cycle -- star birth. The colors in the ALMA data represent the relative Doppler shifting of the millimeter-wavelength light emitted by carbon monoxide gas. The blue color represents gas approaching at the highest speeds; the red color is from gas moving toward us more slowly. The background image includes optical and near-infrared imaging from both the Gemini South and ESO’s Very Large Telescope. The famous Trapezium Cluster of hot young stars appears towards the bottom of this image. Image credit: ALMA / ESO / NAOJ / NRAO / J. Bally / H. Drass et al.

Around 500 years ago, two protostars had a perilously close encounter that blasted their stellar nursery apart. The Atacama Large Millimeter/submillimeter...
