A new 3D map of interstellar dust with Gaia! 🌌 A new study, led by Marie Barbillon, exploited the spectroscopic parametriser from Gaia DR3 to build a high-resolution extinction map! It extends up to 4 kpc from the Sun, with a finer version focused on the Local Bubble area. #astro #galactic

In 2020, Google’s AI lab released a tool called Alphafold that could predict how amino acids would fold into proteins under many different scenarios. Here’s where it—and its Nobel-winning team—are five years later.

We need a reimagined LPSC flavored meeting and the locale should be Tucson in March, after the gem show. Plenty of hotel choices along the free tram line that goes to the convention center. Visit Tucson is onboard to support this. If anyone has the bandwidth to invent the meeting we've got the city.

Question for the #exoplanets crowd: Does any one know where to find an updated version of this plot? I'm looking for the "standard" exoplanet mass vs. semi-major axis plot, but with an overlay of which planets have a spectroscopic measurement of their atmosphere wasp-planets.net/2020/09/29/w...

Glad to have toured the Stratospheric Observatory for Infrared Astronomy (SOFIA) at the Pima Air & Space Museum. Amazing to see the aircraft that carried infrared astronomy above the clouds, I almost got the chance to fly on it. #spacescience #astronomy #NASA #DLR

‘An Overview of Exocomets’ is a very comprehensive review led by Daniela Iglesias started at an @issibern.ch meeting. I worked on Figure 1 detailing comets around the Sun, Beta Pic and a white dwarf - I’m very proud of it, and it is available on @github.com: Exocomet systems #astrodon #exoplanet ☄

Seeing some beautiful photos of aurorae tonight, so here's a reminder that other planets get them, too! This is Saturn, with aurorae visible at both poles in this UV image from Hubble's Space Telescope Imaging Spectrograph, taken in October 1997 when the planet was 1.3 billion km away.

🔭🧪🎢 PhD Project focus: Understanding protoplanetary disc evolution We're advertising this project with Prof Richard Alexander, making simulations of accretion of planet-forming discs onto their star. For details of all our PhD projects look here: le.ac.uk/study/resear... 🔭🧪🎢

🧵 Here is the Nebra sky disk, considered by some the oldest known illustration of the night sky. The artifact was discovered near Nebra alongside several Bronze Age weapons and is linked to the Unetice culture, which thrived in parts of Europe... ➡️ apod.nasa.gov/apod/ap18031... 🔭 🧪 #histsci 1/4

This weekend I read that the entire Breaking Bad franchise is estimated to have had $385M in economic impact for the state of NM and this is celebrated by a statue at the ABQ convention center. Meanwhile University of Arizona space science has an economic impact of $560M on our state every year.

Enjoyed giving a UofA Origins talk on how protoplanetary disks evolve – featuring new results from ALMA and JWST. The recording is available here 👇 youtu.be/mdgGgnjVbb0 @uarizonalpl.bsky.social @stewardobservatory.bsky.social

Congrats to my student Dingshan Deng on a new paper! 🎉 A self-consistent thermochemical model to measure disk masses, fully consistent with dynamical estimates – no need for ×100 CO depletion! Enables reliable disk-mass estimates for many more stars. #ALMA #Astronomy @uarizonalpl.bsky.social

This is devastating, and part of a larger move to entirely push science out of NASA's mission. It is horrific betrayal of so much work, not to mention the fact that it violates NASA's charter.

2019: "NASA is one of the most recognised, revered and iconic brands in the world" (davidsonbranding.com.au/nasa-modern-...). 2025: >1000 NASA mission-support staff (and 2800 other NASA employees) have left under the current administration.

It’s depressing how much faster it is to break a thing than it is to build it

Thank you Mitchell Anderson for your Letter to the Editor in today's Daily Star.

Call it millennial cynicism if you like, but I truly believe nothing will turn the Republican base or leadership against Trump. Our only hope is getting young voters to turn out for elections, and every march/petition is useful only if it serves that goal.

DEMAND CISCOMANI MUST DO THE RIGHT THING. Tomorrow - July 2

Great result led by Kate Su at the University of Arizona: discovery of gas released by a giant impact around a 150 Myr-old star – glad to have contributed! #JWST #DebrisDisks #Exoplanets @jwstfeed.bsky.social @uarizonalpl.bsky.social @nasaexoplanets.extwitter.link

Meet your new cosmic neighbors ☄️ Introducing a swarm of over 2100 new asteroids discovered by NSF–DOE Rubin Observatory! Rubin discovered these asteroids in about 10.5 hours of observing across 7 nights. They've never been seen by humanity before...until now.🔭🧪 youtu.be/DTuq-vBsDJE

Because it's not being said as part of this press conference, @vrubinobs.bsky.social would not be possible without the many, many international scientists and collaborators, some around the world, but many who immigrated to the US and are scientists and engineers here

Here it is: www.youtube.com/watch?v=MIJf...

Zeljko talking about galaxies in @vrubinobs.bsky.social data, and showing off some amazing nail polish. A reporter asked what’s up with the color: it’s the signature observatory color scheme… branding!

I attended a meeting: "Recovery plan for Ukrainian astronomy" organized by @unileiden.bsky.social @astro4dev.bsky.social It was great to interact with Ukrainian astronomers, learn about their science and challenges. I look forward to fostering new collaborations in both the Netherlands and Poland.

Sen. Alex Padilla, who was just forcibly removed from a DHS press conference, is the ranking member of Judiciary’s subcommittee on immigration, citizenship, and border safety, which has “oversight of federal agencies with citizenship, asylum, refugee, and immigration enforcement responsibilities.”

It’s been a privilege to serve as Chair of the Executive Committee for NASA’s Exoplanet Exploration Program Analysis Group. I’m pleased to pass the torch to Prof. Ian Crossfield and look forward to his vision and leadership. #NASA #Exoplanets

Big congrats to Dr. Galen Bergsten on earning the title! If you’re wondering how many Earth-like planets are out there, Dr. Bergsten is the one to ask. #proudadvisor #Exoplanets #Astrophysics

This is seismic. Isaacman had clearly articulated a strong support for science, and the withdrawal of his nomination yet further imperils NASA's Science Mission Directorate. www.semafor.com/article/05/3...
