The environment of massive stars is salty!

In 2019, a team of astronomers led by Drs. Adam Ginsburg and Brett McGuire detected the chemical fingerprints of table salt - Sodium Chloride (NaCl) - and other similar salty compounds, about 1500 light-years from Earth, in the dusty disk surrounding a young star in the Orion Nebula. Since then, eight more salty disks have been detected, suggesting that salt emission is not rare in star-forming environments.
