The search for life beyond Earth is a key driver of modern astronomy and planetary science. The U.S. is building multiple major telescopes and planetary probes to advance this search. However, the signs of life--called biosignatures--that scientists may find will likely be difficult to interpret. Figuring out where exactly to look also remains challenging.
