Once again, don’t trust the output of any #AI assistant without verification. This is not the HR 8799 exoplanet system, it’s the YSES 1 exoplanet system.

Amazing Worlds of Science Fiction and Science Fact by Keith Cooper, 2025
With a stellar cast of scientists and science fictionists alike, a vivid exploration of realities behind imaginary planets. Have you ever wondered what it would be like to watch a double sunset on Tatooine, stand among the sand dunes of Arrakis, or gaze at the gas-giant planet Polyphemus from the moon Pandora?
What do these two things have in common? We'll tell you all about it tomorrow! And you'll get to play with one of them, too

Together with Sebastiaan Haffert our review on “High-Contrast Coronagraphy” is out - writing an ARA&A review has been on my academic bucket list, and I’m very proud of the result. It uses the showyourwork! framework, making it a completely reproducible paper. #FAIR #astrodon #exoplanets https://arxiv.org/abs/2506.02907
An international collaboration called exoALMA is using our telescopes to s peer through the dusty disks where planets are born. Thanks to their newly developed advanced imaging techniques, exoALMA has revealed the most sharp images of young solar systems, as never seen before. This research project has just published 17 papers, with several more coming on the several months.
The exoALMA collaboration is using ALMA to conduct a comprehensive planet hunting campaign in the sub-mm regime. They claim to be the first to focus on still-forming planets, instead of fully formed ones.
Unlike traditional planet-hunting methods that look for a young planet's direct light, exoALMA looks for the effects planets have on their surroundings. This approach potentially allows to detect much younger planets than ever before. "It's like trying to spot a fish by looking for ripples in a pond, rather than [the] fish itself.”

@Lazarou@mastodon.socialWe are getting closer to seeing that "small blue dot" around another nearby star....so long as Elon and Trump don't close it all down out of spite
Maybe they are that racist they hate Aliens too? Fuck only knows what goes on in their Mediocre White Male brains.
It's like anything that gives people hope or joy, they want to control or destroy.

“Using data from ESO’s VLT, a team of astronomers has successfully peered into the atmosphere of an exoplanet for the first time.”
“VLT’s data allowed the team to create the first three-dimensional map of an exoplanet’s atmosphere, revealing wind layers”

NASASpaceFlight.comAn Exoplanet’s Supersonic Jet Stream
WASP-127b is a hot Jupiter-type exoplanet located about 520 light-years from us. A new study of the planet’s atmosphere reveals a supersonic jet stream whipping around its equatorial region at 9 kilometers per second. For comparison, our Solar System’s fastest winds, on Neptune, are a comparatively paltry 0.5 kilometers per second. The team estimates the speed of sound — which depends on temperature and the atmosphere’s chemical make-up — on WASP-127b as about 3 kilometers per second, far below the measured wind speed. The planet’s poles, in contrast, are much colder and have far lower wind speeds.
Of course, these measurements can only give us a snapshot of what the exoplanet’s atmosphere is like; we don’t have altitude data, for example, to see how the wind speed varies with height. Nevertheless, it shows that exoplanets beyond our planetary system can have some unimaginably wild weather. (Video and image credit: ESO/L. Calçada; research credit: L. Nortmann et al.; via Gizmodo)

@Lazarou@mastodon.socialI guess by DECREASING the bio-diversity of Earth as well as fucking with the Weather the Capitalists are making other worlds more habitable ("Superhabitable") in comparison.
I imagine the planet in Scavenger's Reign could be described as 'Superhabitable', and the term doesn't say it's superhabitable to Humans and our needs, just to Life.
(also considering a 'Brain Thompson' to get a 2nd season of that show!)

I just read through my latest #introduction and it’s so outdated 
Hello friends 
My name is Bibi and I am a final-year #PhD student in #astronomy and #astrophysics at Lund University in Sweden.
I observe #exoplanets with big #telescopes to study their atmospheric composition 
I recently spent a year in #Chile at #ESO, and now I am writing up my #thesis, and I am applying for #postdocs
I am the first in my family to go to uni, so you’ll definitely hear me talk about that 
#scicomm
The Anti-Life Equation (Fermi Paradox) fears the Incarnation.
I wonder if the alien equivalent of exokikes and exoniggers ended E.T. civilizations in the distant past?
