Life On Saturn’s Moon Enceladus Would Be Possible
[University of Regensburg] From a human perspective, Enceladus is anything but a comfortable place to live: Icy cold, hardly any oxygen, and – below its icy crust – a global […]

Following Ancient Rain Toward The Origins Of Life On Mars
[Tohoku University] The Mars we know today is a cold, dry world of dust and rocks. However, around 3.8-3.6 billion years ago, it may have looked very different. Geological and […]

Atmospheric Dynamics And Variability Of Periodically Irradiated Tidally Locked Planets
[astro-ph.EP] Time-variable stellar heating may create new climate states, such as permanently hot or cold hemispheres, on asynchronous planets. Planets on eccentric orbits, circumbinary planets and planets on polar orbits […]

Flow Dynamics Of Cryolava Or Impact Melt On Titan’s surface
[astro-ph.EP] Titan, a unique body in the solar system, resembles a life-size Miller-Urey experiment where pockets of liquid water might interact with abundant organic matter.

Space Journey Beyond Earth: Exploring The Properties Of Exoplanets And Multi-planetary Systems
[astro-ph.EP]. In contrast to the observed exoplanet diversity, planets within many multi-planetary systems exhibit intra-system similarities in their radii, masses, and orbital spacings.

NASA Scientists Search For Clues About Mars’ Past In Scotland
[NASA] This summer, NASA scientists headed to the Scottish Highlands to follow up on last year’s announcement of potential biosignatures on Mars and prepare for future research.
![D.2: Transit signals recovery analysis in the TESS light curve of TOI-210. TOI-210 b is shown in gold at its period of 9.01 days. Candidate planets at 2.15 and 3.76 days tentatively detected in the NIRPS RVs are indicated as lower limits, with arrows extending from minimum (iron density) to realistic (Earth density) radii based on their minimum masses. The expected transit depths fall within the TESS sensitivity, suggesting that if these RV signals are planets, they are unlikely to be transiting. -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/10/A-temperate.png?resize=1200%2C713&ssl=1)

A Temperate Sub-Neptune Transiting The M4 Dwarf TOI-210 Identified By NIRPS And TESS — Uncovering Hidden M-dwarf Planetary Systems In The Near-infrared
[astro-ph.EP] Super-Earths and sub-Neptunes dominate the exoplanet population, yet their compositions, formation mechanisms, and capability of retaining atmospheres remain poorly understood. M-type stars offer a unique opportunity to investigate these […]
