Satellite spotting and caffeine high at the best telescope in the world (TBTW, SMARTS 0.9m). @noirlabastro.bsky.social

Just finished a complete night of observation. Dusk to dawn! Two more nights to go, all I am praying for now is some sleep.🫩

Paper day! You're doing ground-based high-resolution exoplanet transmission spectroscopy and want to analyse the planet—not the star or Earth's atmosphere. Is there a way to disentangle your spectrum *without* destroying the planet signal? arxiv.org/abs/2509.12737 🧵⬇️ 🔭 #exoplanets #astromethods

Okay, now that I can stop talking with all caps, why is this important? So, we're looking for planets like Earth, right? It's the only place we've found with life so far. What makes it "Earth"? Well, some things include being a rocky planet, and being the right temperature for liquid water. (1/N)

Wound up with some cool @uchile.bsky.social merch and got a chance to interact with students from various departments at the International Graduate Student Gathering 2025😊 #fcfm #uchile

Kepler mission: smaller stars have more short-period, small #exoplanets. Theory: the smallest stars won’t have enough disk material to make small planets so there must be a turnover. Kepler+K2: We have found a turnover! Check out our newest Scaling K2 paper: arxiv.org/abs/2508.05734 🧵 1/9 🔭🧪☄️

Finding atmospheres would be great, but not finding them would be profound! (In the case of M dwarfs) - Jacob Lustig-Yaeger #sagan2025 #exoplanets

Exoplanet demographics are key: Integrative. A key point from today's talk by Daniel Apai at #sagan2025 on future prospects of key planetary processes and trends in the sub-Neptune population. #exoplanets

Panel: Demographics of life in the universe! Bio-signatures or Techno-signatures in the next 20 years? #ssw2025 #exoplanets

ALMA found evidence for complex organic compounds, such as sugars & amino acids, in a protoplanetary disc. Thus, discs may inherit these complex molecules from interstellar clouds. More in this press release by @mpi-astro.bsky.social : https://www.mpia.de/news/science/2025-05-v881-ori 🔭 🧪

What does the radius valley tell about the planet formation scenario around low mass stars? And how does it connect it with water worlds? To know more, come visit my poster #37 at SSW2025. #sagan2025 #exoplanets

Ever been to a party so good you couldn’t stop talking about it? Same here 🥳 #RubinFirstLook was unforgettable, and made even more incredible thanks to 360+ Watch Parties around the world celebrating with us on June 23! 🔭🧪 Enjoy this trip down memory lane with us 🤩

Just curious, with an MBA degree, will I also be able to open a deep dish pizza restaurant?🤨

Why does the solar system not have super-Earths? A thread #exoplanets ☄️

Caricature me!

i hate how much of life these days is keep reading news that is beyond my control and overwhelmingly horrifying or idk go look at a spreadsheet and another documentary about theme parks

too normal to make it on elon’s twitter, not annoying enough to libpost on bluesky, too poor to be an instagram influencer… what’s a 30-something internet microcelebrity to do

From guest author Sakhee Bhure: We always say we’re made of stardust, but are we actually made out of our star’s dust? Today’s paper discusses the link between stellar composition, and their host planet composition, in order to answer that question. 🔭✨☄️ astrobites.org/2025/06/06/s...

Just some camellids looking towards a relaxing weekend! #LagoChungarà

If #RCB can do it, so can we all! #IPL2025 #EeSalaCupNamde #Bengaluru

Maybe not a good time to be online anymore! I moved to Bluesky from Twitter/X in hopes of optimistic & happy astronomy news but looking at the NASA cuts is making me crawl back to my bed.🫠

"Why should my tax dollars go to fund your astrophysics research?" A thread. 🔭🧪 Brushing aside how absurdly little of the federal budget goes to science (according to the Planetary Society NASA accounts for only 0.3% of federal spending), the benefits of funding astronomy fall into two camps. (1/n)

Fall sunsets in Santiago are definitely on the top!

Ready for the latest K2-18b drama? Madhusudhan is claiming *even stronger* evidence of DMS after analysing both near-infrared and mid-infrared JWST data. But another study finds no evidence at all. Read on for a quick update on everyone's f̶a̶v̶o̶u̶r̶i̶t̶e most newsworthy exoplanet. 🧵 #exoplanets 🔭

It's that time of the year, again. #bengaluru

The K2-18b saga continues. I’ve been waiting for someone to do a joint NIR and MIR analysis of the JWST data, this paper on the arxiv does exactly that, and demonstrates the lack of evidence for DMS 🔭 🪐 arxiv.org/abs/2505.13407

Monday motivation! ✨

The ruins of Hampi, on the shore of river Tungabadra. The intricate and delicate carvings tell all the story we need to know. #ಹಾಳುಹಂಪಿ

Bright flora for a gloomy day.

Friday thoughts!?😶‍🌫️

Back in 2022, had the absolute pleasure of observing #exoplanets transits with SMARTS 0.9m Telescope, Cerro Tololo Inter-American Observatory, Chile.

Day 1 of fun PhD banter!✨
