We present the combined JWST/NIRSpec G395H and NIRISS SOSS transmission spectrum of a warm mini-Neptune, TOI-1130b (3.66 R⊕, 19.8 M⊕, Teq∼825 K). It is part of a rare and unique […]
A study of NASA’s TESS (Transiting Exoplanet Survey Satellite) data on stellar pairs undergoing mutual eclipses has uncovered more than two dozen candidate exoplanets, or worlds beyond our solar system. […]
We present detailed asteroseismic modelling of 95 main-sequence solar-like stars and Kepler exoplanet host stars using the FICO procedure, a three-step method that combines forward and inverse techniques that enables […]
The next few years will be critical for technology development for Habitable Worlds Observatory (HWO) in its mission to search for and characterize extrasolar planets.

![WASP-39b transmission spectra and cloud scenarios. Spectra are observed with JWST (orange), HST (magenta), and VLT (green) in comparison to models with different Fe content: full IWF Graz cloud model (black line), Fe[s] replaced (dark gray), FeS[s] replaced (middle gray), and all Fe-binding materials replaced (light gray). The Fe-free mixed-material cloud compositions provide a good fit in the near-IR but not in the optical. — astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/04/Exoplanet-climate.png?resize=1200%2C718&ssl=1)
Context. Space missions such as CHEOPS, JWST, and PLATO facilitate detailed characterization of exoplanets, particularly close-in gas giants and their wide range of global temperatures and climate regimes.
NASA’s Curiosity and Perseverance rovers have captured two 360-degree landscapes that highlight how the missions are revealing details of the Red Planet’s formation, watery past, and potential for life (astrobiology).
The Habitable Worlds Observatory (HWO) aims to image and characterize at least 25 ExoEarth candidates (EECs). Achieving this goal requires a detailed understanding of the observatory’s design trade space, including […]
The European Space Agency Plato mission has successfully completed a series of tough tests under space‑like conditions. With this accomplishment, the spacecraft is on track to lift off in early […]
The surface and subsurface of worlds beyond Mars remain largely unexplored. Yet these worlds hold keys to fundamental questions in planetary science – from potentially habitable subsurface oceans on icy […]
