PhDone :)

TWO recently accepted papers on arxiv today from our group, led by PhD students @maddielam.bsky.social and @astrotoole.bsky.social. If you like brown dwarfs, variability, clouds, aurorae and/or magnetic spots there is something here for you! 👀

hey all, I am excited to share that I will have my defense on April 17th! Let me know if you’d like a zoom link for the open part! :)

in my mind you’re so insanely busy that I am just happy to see you took a break. 😅

i’m excited to share something that people already know: @philip-armitage.bsky.social ‘s 2011 and 2024 review papers are AWESOME.

it me

yup that’s me🤣

Two satellite proposals threaten dark and quiet skies worldwide 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?

Imaging Venus-like Worlds: Spectral, Polarimetric, and UV Diagnostics for the Habitable Worlds Observatory Understanding planetary habitability requires a comparative approach that explores the divergent evolutionary outcomes of Earth and Venus. The Habitable Worlds Observatory (HWO) will be uniquely posit...

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?

NASA’s Pandora telescope will study stars in detail to learn about the exoplanets orbiting them The findings from Pandora will complement data from the James Webb Space Telescope to give astronomers more insight into stars and planets outside our solar system.

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...

Constellations and Supernovas Support our Astronomy+Arts collaboration in bringing “Constelaciones y Supernovas” to Seattle in Spring 2026!

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.
