Earth-mass Planets With He Atmospheres In The Habitable Zone Of Sun-like Stars
The discovery of many low-mass exoplanets, including several planets within the habitable zone of their host stars, has led to the question of which kind of atmosphere surrounds them.

An Informational-Entropic Approach to Exoplanet Characterization
In the past, measures of “Earth-likeness” of exoplanets have been qualitative, considered an abiotic Earth, or required discretionary choices of what parameters make a planet Earth-like.

Where To Find The Next Earth
A team from the University of Bern and the National Centre of Competence in Research (NCCR) PlanetS has developed a machine learning model that predicts potential planetary systems with Earth-like […]
![Odds ratio of the hypotheses that abiogenesis is a fast vs slow process. Each curve represents the odds ratio, computed using Equation 1, as a function of the biosphere’s ultimate lifespan, T - although we have subtracted off the modern epoch to yield remaining time on the x-axis. Previous estimates [1, 8] for the earliest evidence of life yield the dotted and dashed lines, but the new LUCA date of 4.2 Gya [10] greatly improves the odds factor. Indeed, the three solid lines show how the odds are always above 10:1 irrespective of how one chooses T or indeed fairly extreme choices (Carboniferious and Cambrian period) for the earliest civilization on Earth, t ′ I - evident by the circles which denote the minima. -- astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/04/Strong-Evidence-That-Abiogenesis.png?resize=1200%2C721&ssl=1)

Strong Evidence That Abiogenesis Is a Rapid Process on Earth Analogs
The early start to life naively suggests that abiogenesis is a rapid process on Earth-like planets. However, if evolution typically takes ~4Gyr to produce intelligent life-forms like us, then the […]
