Microbial Methanogenesis on Mars: A Life Detection Target For An MLE-Type Mission And Future Human Exploration
[astro-ph.IM] Methane (CH4) is one of the most enigmatic and potentially consequential trace gases detected on Mars, having demonstrated apparent seasonality, localized plumes, or, depending on who you ask, never […]

Identifying Deformed Exoplanets With JWST And Ariel: A Target Selection Metric For Phase Curve Observations
[astro-ph.EP] The shape of an exoplanet encodes fundamental information about its internal structure. For close-in giant planets, strong stellar tidal forces induce measurable deformations that can be probed through high-precision […]

Robustness Of C/O And Mean Molecular Weight Under Disequilibrium Chemistry
[astro-ph.EP] Transmission spectroscopy increasingly reduces exoplanet spectra to derived compositional metrics, such as C/O, O/H, and mean molecular weight (MMW), but these quantities do not carry molecular abundance uncertainties in […]

Millimetre/Sub-Millimetre SETI: Expanding The Radio Technosignature Parameter Space With ALMA2040
[astro-ph.IM] The search for extraterrestrial intelligence (SETI) has been largely concentrated at centimetre wavelengths, and in particular in the ‘water hole’ (1.42-1.66 GHz) range. The millimetre and sub-millimetre sky is, […]

A New Method For Constraining 3D Exoplanet Atmospheres: Application To WASP-94A b’s Panchromatic Spectrum
[astro-ph.EP] A growing number of transiting exoplanets exhibit spectroscopic evidence that their leading and trailing limbs differ. Interpreting these observations is now the limiting step.

SwRI Staff Contribute To New Ideas About Origins Of Uranus And Neptune
[SwRI] Uranus and Neptune are often considered planetary twins due to their many similar characteristics, including size, mass and atmospheric conditions, and have long been thought to have pulled from […]

A Voyage Into The Slow-motion World Of Earth’s Deep Seas
[Helmholtz Centre for Ocean Research Kiel (GEOMAR)] Polymetallic nodules form at a snail’s pace. They grow about one to two millimetres over the course of a million years. If buried […]

Rosalind Franklin Rover Stand-In Tackles A Tilted Descent
[ESA]. A full-size model of the rover tackled slopes, boulders and Mars-like gravity as it stepped onto a simulated martian terrain during a two-month test campaign on Earth.
