There's table salt on one of Jupiter's moons



Let's go back to an experiment for years ago to understand this one better. Back in 2015, JPL scientist Kevin Hand put ocean salt samples in a lab under European conditions and bombarded it with radiation. His sodium chloride sample changed color, turning a look like a yellowish area on the moon called Tara Region. Since the STIS also spotted a spectral signature matching irradiated sodium chloride on Tara Regions scars, the new study's results suggest that the area truly is abundant in sea salt.

Whether that means the Jovian moon is friendly to life remains to be seen ̵
