Euclid Flagship 2 Update The largest ever synthetic galaxy catalogue is now public; a team of 8 institutions within the Euclid Consortium, led by the Institute of Space Sciences (ICE-CSIC) and the Port d’Informació Científica (PIC)in Barcelona have developed this `mock' catalogue, which includes…

I think that this is a *huge* result for galactic dynamics & stellar streams - the fact that our galaxy's disk is probably full of *thousands* of these streams is amazing! Far more are detectable than previously thought - thanks to Sebastian's algorithm, SigMA. 🔭☄️🧪 #galactic

🔭☄️ #galactic A *huge* new review of Gaia data came out today!

☄️Hayabusa2 mission just got more exciting! 💫New observations led by @ua.es #ICCUB’s Toni Santana-Ros reveal asteroid 1998 KY26 is just 11m wide and spins every 5 min! This poses a challenge for the mission, which will attempt a brief ‘kiss’ manoeuvre in 2031 to collect data

Eduard Masana and Hector Linares from our group have produced the first global map of Light Pollution in Catalunya @ieec.cat @icc-ub.bsky.social govern.cat/salapremsa/n...

Do you remember the global #map of light #pollution in Catalonia developed using advanced #modelling? 🌃 Today we introduce the #IEEC – @icc-ub.bsky.social group on Light pollution, who make projects like this possible. Check it out! 👉 www.ieec.cat/en/project/7...

🔵On 12 August 2026, Catalonia will see its first total solar eclipse in over 100 years! 🕶️✨Use 12 August 2025 to check your sunset view and get eclipse-ready 💪The #ICCUB is proud to be part of the scientific outreach efforts, alongside @ieec.cat and other leading institutions

bluesky hive mind: is this unhinged conference poster design actually any good? I really want to make something eye-catching that's not just the normal black-text-on-white-background, so I turned the entire background into the main figure still needs layout, text, & figure work, but basic concept:

HEY friends: recently seen heaps of "disclosures" from AI companies of the energy cost per question you type into chatbots (most recently from Google)? Presenting per-query 'efficiency' is part of big tech's efforts to hide its extremely real and happening-right-now climate impacts! NEW POST -->>>

✨La Real Acadèmia de Ciències i Arts de Barcelona ha inaugurat l’ #EspaiCatalà a l'Observatori Fabra, una exposició dedicada a l’astrònoma pionera Assumpció Català amb la col·laboració de @ub.edu i #FECYT 🔭Forma part de l’ #AnyAssumpcióCatalà, impulsat per #InstitutCatalàDones♀️ 🔗 bit.ly/45VCSeQ

🚨 Un equip internacional d'astrònoms ha descobert el tercer objecte interestel·lar! 🔭 3I/ATLAS, detectat amb la participació de Toni Santana-Ros ( #ICCUB-#UA), és gran, actiu i serà visible durant mesos! 🌌 Una oportunitat única per estudiar un missatger d’un altre sistema estel·lar bit.ly/400vGua

💫Cesca Figueras i Trinitat Cadefau ens presenten l’exposició sobre Assumpció Català amb el seu llegat #científic 🖼️Estarà disponible al #ParcAstronòmicMontsec i per itinerar a escoles, centres cívic i biblioteques +info i reserves👉🏼 dones.gencat.cat/ca/ambits/ac...

🔭Comença l’Acte Central de la Commemoració del Centenari d’ #AssumpcióCatalà, astrònoma catalana pionera! ✨ #TalDiaComAvui naixia la Dra. Català al 1925 a Barcelon, i avui ens trobem per celebrar el seu llegat 🤝🏼Organitzen #InstitutCatalàDones, #ParcAstronòmicMontsec, #FGC i @ub.edu - #ICCUB

ESA's astronomers are actively tracking 3I/ATLAS, which is now the third confirmed interstellar comet to pass through our Solar System! More info at: www.esa.int/Space_Safety...

Postdoc in #stellarastro at the ICCUB in Barcelona ☄️ Everyone I know from the astro community in Barcelona is lovely, so I can highly recommend it!

DR19 is the first big data release for SDSS-V, and the first time @milkywaymapper.bsky.social is featured: this mapper loves stars because stars are cool (or hot), but also because they can tell us how the Milky Way formed www.sdss.org/dr19/mwm/abo... #DR19

Yesterday we released our nineteenth data release into the wild: www.sdss.org/dr19, let’s now take a closer look on what is in this data release. #DR19

NASA is more than rockets and moonwalks. NASA is behind much of our everyday technology. From space discovery, to Air Jordans, to CAT scans, NASA has played a role. We get it all on less than a penny of every federal dollar. Now their science may be gutted by 50%. #NASADidThat

From Kaz Gary: For Pride Month, Astrobites is interviewing one transgender astronomer every week. This week we interviewed Joy Bhattacharya, a PhD candidate at the Ohio State University! 🔭✨☄️ astrobites.org/2025/06/13/j...

Interesting paper. I definitely think that addressing and discussing LLM use with students is essential - there is no escaping the fact that almost all students now use LLMs every day.

Bitcoin mining has been nothing more than a huge energy waste in past years. Now AI is about to surpass Bitcoin’s power demand. Emerging tech is rapidly driving up the power demand of worldwide digital infrastructure with the inevitable consequence being strained power grids and more fossil fuel use

An absolutely fantastic textbook on statistics and machine learning by Prof. Yuan-Sen Ting came out this week - and it's free! #astromethods ☄️ I had a read and it's incredibly comprehensive and well-written - I expect this to become *the* foundation book on stats & ML basics in astro.

Hey, the PDF of my 3-hour workshop at the U. of Delaware has over 100 downloads now! Not bad! zenodo.org/records/1511... If you teach science, give your students the time and opportunity to find their own #writing voices. Textbook I wrote for my #JHU students: www.press.jhu.edu/books/title/... 🧪⚛️🔭

This is the culmination of 18 months of work to try and start treating incompleteness in cluster catalogues better. 🔭☄️🧪 #galactic But this work is just the beginning! We've already made major progress on an all-sky cluster selection function -see my talk on Thursday in S1 here at #EAS2025Cork!

After correcting for selection effects, we find that old clusters are much more common in the anticentre. Compared to the solar neighbourhood, the edge of our galaxy has 3x as many old clusters - suggesting either migration or lower cluster destruction+formation rates are at play. 🔭☄️🧪 #galactic

🔭

How many open clusters could be hiding at the edge of our galaxy? 🔭☄️🧪 #galactic Our new paper out today (A&A, accepted) pioneers a new way to test the completeness of cluster catalogues built with @esa.int's Gaia mission!

Wondering what to do at #EAS2025Cork tomorrow? Come along to SS45, which is the early career researchers session! In the morning (9:40) I'll be giving a talk about the astronomy feeds - how they started, how they work, and how to make the most of social media as an ECR 🔭☄️

DR4 will contain 2.5 billion sources along with time-series astrometry, photometry, and radial velocities - totalling 0.5 petabytes of data ☄️

250 million radial velocities to be released, 85 million of which are reliable - 3x more than DR3 ☄️

More on DR4: it's expected to include "a few thousand" exoplanets, potentially doubling or tripping the number of known exoplanets! ☄️ #exoplanets

Finding out about Gaia at #EAS2025Cork! ☄️ Just announced: Gaia DR4 will be released in December 2026!

"However, the need for more knowledge must not be paralyzing since reducing pressures can only go in the right direction for biodiversity protection; then wide range of actions can be implemented without delay and without regret... such as reducing nighttime lighting,..." doi.org/10.1007/s109...

Wind farms and light pollution: Medium-intensity turbine lights can be brighter than the brightest stars and planets on the night sky up to significant distances. This should be taken into account in environmental impact assessments. Version of record, open access: doi.org/10.1016/j.jq...
