Scientists zoom in on distant solar system. It's teeming with water.

Astronomers are excited about this one. Using a sprawling astronomical array in the lofty Chilean desert — the Atacama Large Millimeter/submillimeter Array (ALMA) — scientists found huge volumes of water around a young, developing solar system (technically still in its "protoplanetary disk" phase). The star, HL Tauri, is located 450 light-years away in space. Yet in the disk around HL Tauri, the powerful observatory was able to spot at least three times the amount of water contained
