it me
yup that’s me🤣
From Tori Bonidie and Magnus L’Argent: Giant mirrors in space to create sunlight at night and an AI data center made up of 1-million satellites are undergoing regulatory approval. How did we get here? ⚛️ 🔭 ☄️ 🧪

I know it's called the "Habitable Worlds Observatory", but what about uninhabitable worlds? Check out the below paper to learn what HWO can teach us about our sister planet and its analogs that are scattered among the stars!

i try not to use these words and just be straight up aggressive 😂
Let me recommend grabbing a cup of tea & reading this really thoughtful piece from the inimitable @hogg.bsky.social on moderating AI/LLM use in astrophysics. 🔭
"the real question we face is not ... how we do astrophysics. It is the question of why we do astrophysics."

Thanks for translating lmao
I think latex doesn’t recognize the word “circumplanetary”
Let me guess…are you a statistician?

Our NASA’s Pandora space telescope is on orbit!! Congrats to the team and NASA, LSP, SpaceX, and everyone who helped to get to this exciting point! What will Pandora do and why is it important for exoplanet science? Read my short article on this: theconversation.com/nasas-pandor...

We're trying to bring a really neat astro-themed art installation to UW from Mexico this spring, and we need your help! We can get the art here, but we're fundraising to bring the artists so they can present and collaborate with us here!
Help us spread the word?

I forgot about AAS completely cause been too stressed! So did I miss the only opportunity to give my dissertation talk? 🥲
Omg this is my worst nightmare
A collage of 32 glowing discs on a black background. Each disc shows concentric rings in vivid colours: purple, orange, and yellow, with bright cyan centres. The discs vary in size and orientation, creating a striking pattern of circular and elliptical shapes.
🐣 Found: newborn stars and planets
#ESAGaia & ALMA joined forces to study 31 baby star systems, finding hints of planets 👉 www.esa.int/ESA_Multimed...
The collage also shows our own Solar System for reference on the bottom right, as it is predicted to have looked at an age of 1 million years. 🔭 🧪

Here, everything is work!
In it alone success, risk, and a song are forever hidden.
And again the Star of Discoveries beckons into the distance -
An unclear, hazy star!
The wonderful fate of a pioneer!
Through dunes, craters, and debris, crushing the soil and the hard ground of alien rocks, our all-terrain vehicle, resembling a beetle, crawls wearily across the desert cliffs.
And I will take the first uneasy step towards the mystery of the unexplored planet.
Not for romance or glory
that we wander far from our native land,
we walk along rivers of frozen lava, sinking waist-deep in dust.
The challenging fate of a pioneer
The challenging fate of a pioneer is forever to my liking and to my heart!
And the suns flash in various colors, like traffic lights, in the alien heights.
...Another moment will pass - and the rocket will land in unknown places.

Scientific poster with dark background and two black holes illustrated in the center. The paper visualizes gravitational waves, and explains how parameter estimation is performed with DINGO. The standard DINGO model and the DINGO-T1 architectures are illustrated and results are shown. For example, it is possible to reanalyze the same event with different detector configurations with DINGO-T1, illustrated bz a corner plot.
1/ 🌀 New paper alert! We introduce Dingo-T1, a flexible transformer-based deep learning model for gravitational-wave (GW) data analysis. It adapts to different detector & frequency settings, improving inference efficiency and flexibility

And fiery seers burned bright upon the stake.
And incomprehensible stars grew dim for the fires’ sake.
In the struggle and humility of Lenten prayer,
back then and now—they blessed the stars or cursed them there.
From caves they gazed in wonder, from towers reached in vain,
tried to grasp the menace and the mystery they contain.
I tried to make it rhyme.
To the stars!
It’s both difficult and simple, wise and seemingly absurd:
people strive for the stars,
people strive for the sky!
