Astronomers first identified these minerals using the now-three-year-old James Webb Space Telescope. To see where exactly the signals were coming from, they studied the system with the ALAMA telescope, which is operated by the European Space Agency with international partners in Chile’s Atacama Desert.

Purdue University’s Merel van ’t Hoff, a co-author, is eager to find more budding planetary systems. By casting a wider net, astronomers can look for similarities and determine which processes might be crucial to forming Earth-like worlds.
