For scientists who want to learn about the geological history of a planet, river deltas are a great place to start. Deltas gather sediment from a large area into one place, which can be studied to reveal climate and tectonic histories or signs of past life. That's why NASA sent its most recent Mars rover to Jezero Crater, home to a prominent and well-preserved delta.

    Titan is the only planetary body in the solar system besides Earth that has liquid currently flowing across its surface, so its deltas could be a scientific treasure trove.

    One problem: Titan appears to be largely devoid of deltas, a new study finds, despite its large rivers of liquid methane and ethane.
