Daguerrotipo tomado al José de San Martín en la agitada París de 1848. Se trata de la única imagen fotográfica que se conoce del general San Martín.

Say it 3 times: Betelgeuse, Betelgeuse, Betelgeuse. Astronomers using @Geminiobs North found a hidden companion star orbiting inside Betelgeuse’s atmosphere, the first close-in companion ever seen around a supergiant star. 🔗 noirlab.edu/public/news/no… 📷GeminiObs/NOIRLab/NSF/AURA

The @LIGO - Virgo - @KAGRA_PR Collaboration is happy to announce the detection of the merger of the most massive black holes ever observed with gravitational waves 🕳️🕳️

‼️✨ Airglow Waves Over the Atacama Desert in Chile near the Pacific Ocean ! It features red airglow waves, an atmospheric phenomenon resulting from molecular recombination in the upper atmosphere. Have you seen anything like that ?

#OrgulloUnab 🙌 @uandresbello entre las 5 mejores universidades de Chile según el Center for World University Rankings (CWUR), una de las mediciones académicas más completas de instituciones de educación superior en el mundo 🌎 La versión 2025 del CWUR posicionó a la UNAB como la N°1 en Chile entre las universidades privadas no tradicionales. Esta destacada posición refleja el compromiso de nuestra universidad con la excelencia académica y la investigación de vanguardia. #SomosUNAB #UnabSantiago #UnabViña #UnabConcepcion #ExcelenciaAcademica #EducacionSuperior

🚨 SAVE THE DATE: The world's First Look at images from @NSF–@doescience Rubin Observatory is coming June 23, 2025! Get ready for a preview of how @VRubinObs will soon #CaptureTheCosmos in its decade-long survey 🌌. More details soon—stay up to date at rubinobservatory.org/news/rubin-fir…

📣 @ESA_Euclid releases its first batch of survey data, including a preview of its very own deep fields! With just one scan, Euclid has already spotted 26 million galaxies, giving us a glance at the large-scale structures of the cosmic web 👉 esa.int/Science_Explor…

The most energetic neutrino ever observed just smashed into the Mediterranean and left a signal that was picked up by the K3Mnet neutrino telescope 2400m under the sea At the moment we don't really know where this neutrino came from, nor should it really be there. 🧵1/10

Our main results: - FLAMINGO reproduces SMG counts & redshift distribution - We find that SMGs (S850 > 1mJy) contribute 27% to cosmic SFRD at z=2.6 - Forecast: @TolTEC_CAM UDS will detect ~80,000 SMGs at 1.1mm

#paperday on #SubmillimeterGalaxies (SMGs) Ankit Kumar (@Galaxtronomer) tested parametric models in EAGLE, TNG, & FLAMINGO to explore SMG properties & their role in cosmic star formation. 🌌 See: arxiv.org/pdf/2501.19327

I guess I used to be all about the Milky Way photography, but now ? 😂 I'm more of a comet catcher ! My Instagram's front page is now a comet convention instead of a Milky Way scenes. The Moon and the Sun are the next close ones. Come see where my camera's pointed now ! 🌠🤓📸 @yuribeletsky on IG
