Where in #space can #planets with #atmospheres be found? C. Cherubim et al. (2026) used #nearinfraredspectroscopy to characterize a #rocky #exoplanet orbiting its host star within the #habitablezone. Planet #LHS1140b exhibits #helium #absorption in its atmosphere, a feature the authors attribute to a helium-dominated #upperatmosphericlayer.

The cosmic shoreline concept was introduced to separate #planets with #atmospheres from those without, by relating the cumulative X-ray and extreme-ultraviolet (XUV) instellation to the planetary escape velocity, using the Solar System planets to anchor the empirical relation.

The #exoplanet community has since attempted to refine the cosmic shoreline to provide a consistent ranking or prioritisation tool for exoplanet observations – i.e., to quickly identify which small #planets are most likely to have retained an #atmosphere.

In a new paper, astronomers use an empirical approach to refine the cosmic shoreline concept.

The Empirical Exoplanet Cosmic Shoreline (EECS) exhibits a significantly steeper slope than previously theorized, while consistently categorising Solar System moons and dwarf planets according to their atmospheric properties.

Applied to planets orbiting M dwarfs, the EECS suggests that a larger fraction retain atmospheres than predicted by classical models, but incorporating revised XUV fluence histories for low-mass M dwarfs reveals severe atmospheric vulnerability.

Here is a problem that has been quietly gnawing at astronomers for decades.

The standard approach to detecting #life on other worlds involves scanning #exoplanet #atmospheres for #oxygen, #methane, and #ozone, whose presence is difficult to explain without #biology.

It's a clever idea, but it carries a hidden flaw. That entire shopping list was written by studying Earth. It is, inevitably, a search for life like us.

The list of ways that #chemistry alone can accidentally mimic these #biosignature gases is growing faster than the list of new ways to detect life.

Each new false positive scenario demands even more information about the #planet to rule it out, and there is a genuine question about whether that information can ever be gathered exhaustively.

But there is a solution.

#Assembly theory doesn't ask what #molecules are present in an #atmosphere. Instead, it asks how hard they were to make.

Every molecule can be assigned an assembly index, a minimum number of construction steps required to build it from basic #chemical building blocks.

Simple molecules are easy to assemble by chance, but truly complex ones, requiring many sequential steps, don't arise without something doing a great deal of deliberate selection.

That something would then be life itself.

We live in a very exciting time: answers to some of the oldest questions humanity has conceived are within our grasp.

One of these is whether #Earth is the only place that harbours #life.

In the last 30 years, the question of whether the Sun is unique in hosting a planetary system has been resoundingly answered: we now know of thousands of #exoplanets orbiting other #stars.

But can we use telescopes to detect whether any of these distant worlds also harbour life?

A promising method is to analyse the gases present in the #atmospheres of these #planets.

Astonishingly, we can identify #molecules present in the atmospheres of exoplanets.

Quantum mechanics causes each atmospheric chemical to have its own distinct barcode-like pattern, which it leaves on the light passing through it.

By collecting starlight that has been filtered through an #exoplanet’s atmosphere, telescopes can see the barcodes of the molecules making up that atmosphere.

To take advantage of this, the planet needs to #transit – pass in front of – the star from our point of view.

I was feeling some of the lowest lows of my life last night/today. Then I saw a news article about an exoplanet that’s shaped like a lemon. The universe is so unserious sometimes. Maybe there’s things worth sticking around for after all.

On December 27, 2006, the European space observatory CoRoT was launched. CoRoT‘s two objectives are to search for extrasolar planets with short orbital periods, particularly those of large terrestrial size, and to perform asteroseismology by measuring solar-like oscillations in stars.
