Editor's choice: Souto et al. observe two systems where a young star has a very different carbon-to-oxygen ratio from the surrounding protoplanetary disc. This implies that chemical processes within the disc are affecting the types of #exoplanet forming there. ☄️🔭 www.science.org/doi/10.1126/...

Probably the most difficult article in which I have participated. Difficult system, difficult data collection, lots of both bad and good luck, difficult analysis, interpersonal drama... it had everything 🔭#exoplanets iopscience.iop.org/article/10.3...

Interesting paper by Winterhalder+ about trying to detect reflected starlight from #exoplanets. arxiv.org/abs/2605.16491 This is very hard, because the stellar lines that you want to see smear out if your star rotates fast, as seen from the planet. Some thoughts below, if you're interested... 🧵 🧪🔭

Observations of #exoplanet atmospheres usually produce a combined spectrum of the morning and evening sides. Mukherjee et al. have used JWST to separate the two for a hot jupiter. They find very different spectra: a clear warm wet evening vs a cold cloudy morning. ☄️🔭🧪 www.science.org/doi/10.1126/...

In a new study using the NSF Very Long Baseline Array (NSF VLBA), astronomers have made the first clear, radio-wavelength detection of how interstellar turbulent gas distorts light from a distant quasar. #VLBA #NRAO #CenterforAstrophysics #Quasar #RadioAstronomy #Astronomy

It’s intriguing how two opposite narratives coexist in public perception: the reality of a world competing to detect extraterrestrial life with no confirmed detections yet, and the belief that governments are already hiding evidence of contact. #Astrobiology #UFOs #UAPs

The real #AlienDisclosure is whether the habitable-zone planets of TRAPPIST-1 have atmospheres. If not, extraterrestrial life and civilizations could be far rarer and farther away than we thought. 😰 #exoplanets #jwst #nasa

It’s gonna be a busy but exciting year for #RadioAstronomy next year! Have already seen emails for several conferences! [alt-text: three plots in the image. First is the detection of pulsars. Second is the Wow! signal curve. Last is the Lorimer FRB signal. All annotated with paper citation]

"Hidden deep in the rolling mountains of Appalachia, a peaceful giant keeps watch over the universe. Green Bank, West Virginia, located in Pocahontas County, is home to the Green Bank Telescope (GBT)—the largest fully steerable telescope in the world." #GreenBankTelescope #GBT #WV #RadioAstronomy

The NSF Green Bank Telescope will be getting another paint job this summer! 📡🎨 Thanks to an award from the National Science Foundation, the lower portion of the feed arm will go through the same repainting process as the top half did last summer. #GreenBankTelescope #GBT #WV #RadioAstronomy

Not much discussion about this in the 🔭 community and it's a story worth paying attention to because the US is explicitly invoking the Monroe Doctrine to influence astronomy project development. The US refuses to invest in astro but doesn't want China doing it either. 🧪 #GiftLink thx to my library

New observations from JWST and the Very Large Telescope illuminate the dark feature at the center of a galaxy cluster’s brightest occupant. aasnova.org/2026/05/11/i... 🔭🧪

Next year marks 20 years since the discovery of Fast Radio Bursts, 50 years since the Wow! Signal, and 60 years since pulsars. Pulsars were quickly identified as neutron stars. FRBs remain mysterious, some linked to magnetars. The story of Wow! is still unfolding. #AreciboWow. #RadioAstronomy

🔭 The amazing Claire Marie Guimond @xoplanets.bsky.social is so good at explaining all things (exo)geoscience! 🌋🌍 I learned so much in this A+ interview about… night-side volcanism?! Where energy dissipates through tidally-locked #exoplanets from molten dayside ➡️ volcanoes form on the other side! 🤯

Cake tin telescope? 📡 Yes! These are prototype radio telescopes some folks in our teams are building — the green part is the receiver (all sky) and the cake tin protects from reflections coming from below. Set up an array of many these and you have a powerful instrument! 🔭 #RadioAstronomy

Today i'm heading to La Palma to observe with HARPS-N at the Telescopio Nazionale Galileo, which was almost a second home during my PhD. Its been years since my last visit. I'm low key excited to be back 🔭#exoplanets

Kicking off the Australiasian Orange Meeting today - a 3-day workshop for the Australasian pulsar and FRB community. Tomorrow, i'll be presenting my results from my research which I am very excited about! Here's the title slide feat. Murriyang in this wonderful Alex Cherney photo. #RadioAstronomy

Pretty spectacular to see different isotopologues of water(!) in the spectra from Kühnle et al. in Oxygen and nitrogen isotopologues on cold COCONUTS-2b observed with MIRI/MRS just amazing details zooming in on the spectra. All absorption lines full of information. #astrodon #exoplanets

Astronomers using ALMA discovered that the interstellar comet 3I/ATLAS is made of an astonishingly high ratio of semi-heavy water relative to ordinary water, indicating that its system of origin likely formed under conditions far colder than our own. #Astronomy #RadioAstronomy #3IAtlas #ALMA #NRAO

Pluto was discovered by an American, so it’ll be reclassified as a planet and renamed Planet America — executive order incoming. 😜

I feel like we’re willing to make Pluto a planet again, at least provisionally, if they’re willing to fund astrophysics. I’d say $100 billion/year is reasonable But if you keep cutting our budgets, I swear we’ll keep eliminating them. Hope you like a three planet solar system!

Astronomers using the NSF Very Long Baseline Array (NSF #VLBA) have tracked the orbital motions of a sample of young binary star systems in Orion and calculated the stars’ true masses - something notoriously difficult for young stars shrouded in dust. #Astronomy #RadioAstronomy #Orion #BinaryStars
