Take a biosphere that sequesters the common atmospheric elements, see what's left over, and you might have a truly rich sci-fi sandbox...

NEW TRACK: "THE VEIL"
A haunting collaboration between Bête Noire and Angelspit. This track grips the listener with the weight of bloodshed, lost souls, battlefields, and broken blades. After the last soldiers have fallen, The Veil arrives.

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.

Dramatic contrasts and the geophysics they suggest lead us to a system straight out of classic sci-fi: around a nearby sun-like star, worlds that are Earth-like but are certainly not Earth *twins*.

The greenhouse-blanketed lush super-Earth is a tired trope, but a more rugged version with nigh-Martian highlands? Now we're cooking...

Five New #Planets and the Battle for Their #Atmospheres
https://www.universetoday.com/articles/five-new-planets-and-the-battle-for-their-atmospheres
One of the primary goals of the James Webb Space Telescope (JWST) is to detect atmospheres around exoplanets, to try to suss out whether or not they could potentially support life. But, in order to do that, scientists have to know where to look, and the exoplanet has to actually have an atmosphere. While scientists know the location of about 6000 exoplanets currently, they also believe that many of them don’t have atmospheres and that, of the ones that do, many aren’t really Earth-sized. And of those, many are around stars that are too bright for our current crop of telescopes to see their atmosphere. All those restrictions mean, ultimately, even with 6000 potential candidates, the number of Earth-sized ones that we could find an atmosphere for is relatively small. So a new paper available on arXiv from Jonathan Barrientos of Cal Tech and his co-authors that describes five new exoplanets around M-dwarf stars - two of which may have an atmosphere - is big news for astrobiologists and exoplanet hunters alike.
With the solar motion of Mercury, the geography of Antarctica, and aspects that are utterly alien, my planet Cerberus is coming along nicely.

Inside the ice giants, a layer exists of familiar rains and snows...and often at a pressure range that wouldn't require spacesuits! Could these planets harbor environments that are shockingly Earth-like?

NEW TRACK : 'THE HARBINGER' (Bête Noire Vs Angelspit)
The Harbinger whispers of decay and destiny; an ancient crone delivering the Black Plague to trembling villages.
