  In the search for life in the cosmos, transiting exoplanets are currently our best targets. With thousands already detected, our search is entering a new era of discovery with upcoming large telescopes that will look for signs of 'life' in the atmospheres of t…

• A dusty veil shading Betelgeuse during its Great Dimming.
  Red supergiants are the most common final evolutionary stage of stars that have initial masses between 8 and 35 times that of the Sun 1 . During this stage, which lasts roughly 100,000 years 1 , red supergiants experience substantial mass loss. However, the me…

• Exoplanets as Sub-GeV Dark Matter Detectors.
  We present exoplanets as new targets to discover dark matter (DM). Throughout the Milky Way, DM can scatter, become captured, deposit annihilation energy, and increase the heat flow within exoplanets. We estimate upcoming infrared telescope sensitivity to…

• Broadband Stability of the Habitable Zone Planet Finder Fabry-Pérot Etalon Calibration System: Evidence for Chromatic Variation.
  The comblike spectrum of a white light-illuminated Fabry-Pérot etalon can serve as a cost-effective and stable reference for precise Doppler measurements. Understanding the stability of these devices across their broad (hundreds of nanometers) spectral ba…

• Scalable photonic-based nulling interferometry with the dispersed multi-baseline GLINT instrument.
  Characterisation of exoplanets is key to understanding their formation, composition and potential for life. Nulling interferometry, combined with extreme adaptive optics, is among the most promising techniques to advance this goal. We present an integrated-opt…

• Biogeographical Modeling of Alien Worlds.
  In this article, we partially quantify the biological potential of an exoplanet. We employ a variety of biogeographical analyses, placing biological evolution in the context of the geological evolution of the planet as a whole. Terrestrial (as in Earthly) biod…

• Five carbon- and nitrogen-bearing species in a hot giant planet's atmosphere.
  The atmospheres of gaseous giant exoplanets orbiting close to their parent stars (hot Jupiters) have been probed for nearly two decades 1,2 . They allow us to investigate the chemical and physical properties of planetary atmospheres under extreme irradiation c…

• Viroids and the Origin of Life.
  Viroids are non-coding circular RNA molecules with rod-like or branched structures. They are often ribozymes, characterized by catalytic RNA. They can perform many basic functions of life and may have played a role in evolution since the beginning of life on E…

• Assessment of Isoprene as a Possible Biosignature Gas in Exoplanets with Anoxic Atmospheres.
  The search for possible biosignature gases in habitable exoplanet atmospheres is accelerating, although actual observations are likely years away. This work adds isoprene, C 5 H 8 , to the roster of biosignature gases. We found that isoprene geochemical format…

• A 200-million-year delay in permanent atmospheric oxygenation.
  The rise of atmospheric oxygen fundamentally changed the chemistry of surficial environments and the nature of Earth's habitability 1 . Early atmospheric oxygenation occurred over a protracted period of extreme climatic instability marked by multiple global gl…

• Vertically Resolved Magma Ocean-Protoatmosphere Evolution: H(2), H(2)O, CO(2), CH(4), CO, O(2), and N(2) as Primary Absorbers.
  The earliest atmospheres of rocky planets originate from extensive volatile release during magma ocean epochs that occur during assembly of the planet. These establish the initial distribution of the major volatile elements between different chemical reservoir…

• Carbon cycle inverse modeling suggests large changes in fractional organic burial are consistent with the carbon isotope record and may have contributed to the rise of oxygen.
  Abundant geologic evidence shows that atmospheric oxygen levels were negligible until the Great Oxidation Event (GOE) at 2.4-2.1 Ga. The burial of organic matter is balanced by the release of oxygen, and if the release rate exceeds efficient oxygen sinks,…

• The rotational and divergent components of atmospheric circulation on tidally locked planets.
  Tidally locked exoplanets likely host global atmospheric circulations with a superrotating equatorial jet, planetary-scale stationary waves, and thermally driven overturning circulation. In this work, we show that each of these features can be separated from t…
