Cover Story: This figure illustrates the ability of information entropy to distinguish different types of planets based on their spectra. On the left, simulated rocky exoplanets (blue) show smaller information differences relative to Earth than do gaseous exoplanets (orange). In the center and right, the inverse is true: gaseous exoplanets are more similar than rocky exoplanets to Jupiter and to a hotter (1200 K) version of Jupiter. In the past, assessments of the “Earth-likeness” of a planet have been qualitative, have overlooked the impact of life on Earth, or have relied on an arbitrary set of choices about what parameters make a planet Earth-like. In our work, we introduce a method which addresses these limitations, using modern high-resolution exoplanet spectroscopy to rank the Earth-likeness of exoplanets. View this paper
