In our September 2025 issue, astronomer and Pluto mission leader S. Alan Stern explores how the field of planetary science has transformed during his decades-long career. From the discovery of exoplanets to finding hidden oceans throughout the solar system to the rise of commercial spaceflight, he lists his top five revolutions in planetary science in recent years.
Now, it’s your turn. You might be thinking that your list of top revolutions is not the same as Stern’s. We’d like to hear your ideas, whether they coincide with the list below or include options that aren’t even on it. We’ll use your answers to compile a final reader’s choice list of the top five revolutions in planetary science. Select up to five topics from the list below, including a blank write-in option where you can tell us what we’ve missed!
