[astro-ph.EP] Over 4 billion years, Earth’s atmosphere has been transformed from a composition devoid of molecular oxygen (O2) to one where O2 is now 21% of our modern atmosphere by […]

![Best-fit model spectra and residuals for the HWO and LIFE datasets (grey and black data points with error bars). Shaded regions show posterior predictive intervals, and the lower panel shows residuals in units of σ. Bottom: Residual between the data and model as measured by 1-σ uncertainty. -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/09/on-the.png?resize=1200%2C715&ssl=1)

On The Impact Of Correlated Noise and Spectral Resolution On The Retrieval Analysis Of The Habitable World Observatory
[astro-ph.EP] Finding signs of life elsewhere in the universe is the holy grail of the field of exoplanets. Future space missions such as the Habitable World Observatory (HWO) are under […]

Projections of Earth’s Technosphere: Strategies For Observing Technosignatures On Terrestrial Exoplanets
The search for technosignatures — remotely detectable evidence of extraterrestrial technology — draws upon examples from the recent history of Earth as well as projections of Earth’s technosphere.

Large Interferometer For Exoplanets (LIFE): XII. The Detectability of Capstone Biosignatures in the Mid-Infrared — Sniffing Exoplanetary Laughing Gas and Methylated Halogens
This study aims to identify exemplary science cases for observing N2O, CH3Cl, and CH3Br in exoplanet atmospheres at abundances consistent with biogenic production using a space-based mid-infrared nulling interferometric observatory, […]
