#exoplanet — Public Fediverse posts

It’s amazing what people will do. Here’s a photo of Exoplanet 13562. It looks like an edible Earth fruit. But really, it’s an exoplanet missing its atmosphere. No one knows why the air disappeared, but billions of litres of water is frozen under the blue crust. The planet is bizarrely covered with Lazurite and ancient canals are visible to the naked eye. Someone with a sense of humor, photoshopped this planet to look like a plum. Adding stem and leaves and a little nub in the end. I’m all for a joke, but it’s wrong to say a photograph is something it’s not. People who post a photo and then make up some some crazy Sci-Fi story to go along with it, should be thrown in the stocks and have rotten tomatoes tossed at them. Actually bananas, have bananas tossed at them. I like bananas. Bananas are good.

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.

Detected: Rocky, habitable-zone #exoplanet with an #atmosphere
A team of astronomers has detected evidence of an atmosphere on a rocky planet orbiting in the habitable zone of its host star.

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.

Paper by Walker et al. (2026): https://arxiv.org/abs/2603.11086

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.

World's darkest and clearest skies at risk from industrial megaproject.

Since its inauguration in 1999, #Paranal Observatory has led to significant #astronomy breakthroughs, such as the first image of an #exoplanet and confirming the accelerated expansion of the #Universe.

Now Paranal is threatened by an industrial megaproject, planned to be located just 5 to 11 kilometres, which would cause irreparable damage to astronomical observations due to light pollution.
