Jovian Moon Was Probably Captured

New observations of Jupiter's moon, Amalthea, reveal that it probably didn't form with the giant planet. The observations were made with the powerful Subaru Telescope on Mauna Kea, Hawaii, which found that Amalthea has unusual amounts of water-carrying minerals. These typically form in low temperature environments.

Astronomers theorize that Jupiter's moons formed from several small objects merging together, and Amalthea could be an example of one of these building blocks that never had a chance to merge.
