I am very happy to announce, together with @DrJorgeMelendez , the @IAU_org Symposium 395: Stellar populations in the Milky Way and Beyond https://t.co/36hRBz2dR5 - a symposium to honor the career of Prof. Beatriz Barbuy. in the historic town of Paraty, in Brazil, this November.

Reading a Chapter of Galactic History from a Single Star

The star SOS1 is not like its neighbors — what do high-precision chemical abundances tell us about where this star might have come from? https://t.co/x3Vy1OWyG2

💫 SOS1, a star that stands out in the Milky Way's central bar.🌌 #astronomy #milkyway

Não podia ter momento melhor para o Brasil levar o Globo de Ouro pela atuação da Fernanda Torres, dois dias antes do ato em defesa da democracia. Eu e a Janja parabenizamos essa grande artista mais uma vez. O país inteiro vibrou. Somos filhos de um Brasil que vale a pena, Fernanda.

Ancient stars discovered on the thin disk of the #milkyway ! Surprising number of ancient stars on sun-like orbits discovered based on data from the @ESAGaia mission. These formed the thin disk of the Milky Way billions of years ago. #MachineLearning

The extreme rainfall that led to unprecedented floods in Brazil’s southern state of Rio Grande do Sul was made twice as likely by human-caused climate change 🌧️

The downpours were also intensified by El Niño, while failures in flood defences worsened the impacts. 📷

Have you wondered what shipping the world’s largest camera took? Hear about from the logistics leader herself, Margaux Lopez, in this new video from @SLAClab! 👇

[Cristina Chiappini @CrisChiap]

Dear fantastic and busy astronomers… as expected :) the number of abstracts jumped from around 150 to more than 300 in 24 hours. Thanks to a great SOC we have already distributed talks and posters. We do have a long waiting list. Please let us know if your plans have changed.

[Cristina Chiappini @CrisChiap]

Dear friends and colleagues, tomorrow (April 17th) is the deadline for registration/abstracts and IAU grant submission for our IAUS395. We have already reached our 150 participants soft-goal :) but we will be still accepting abstracts coming in until the deadline of April 17th.

@Pimenta13Br Muito obrigada por todo o trabalho que você, junto ao governo Lula, tem feito.

Tragédia no Rio Grande do Sul: tá na hora do agronegócio ser cobrado

O agronegócio, isento de impostos, exporta tudo que pode e desmata sem piedade, com a ajuda de políticos da extrema-direita que desmontam a política ambiental do país

Reminder: global warming brings a lot more extreme rain 🌧️ 🌧️ 🌧️. It’s basic physics, the data prove it, and climate scientists have warned you for 30 years about this.

How can we not love Gaia? A halo black hole coming from a collapse of a very metal poor massive star that was caught nearby when crossing the disk! Not enough? And maybe accreted from an external galaxy! Congrats!!!!!!

[ESA Gaia @ESAGaia]

Gaia spots Milky Way's most massive black hole of stellar origin! It's 33 solar masses, dormant, 2nd closest to Earth at ~2000 light years away, part of a wide binary with an old giant star, with estimated age of 11 Gyr: https://t.co/m26bbmpyFO #GaiaBH3 https://t.co/AllbZqVjQY
