This striking new view of the Pinwheel Galaxy combines X-ray light from Chandra with other types of light from ground-based observations, @NASAHubble, and XMM-Newton. The galaxy is roughly 170,000 light-years across, making it about 70% larger than our own Milky Way Galaxy.🌀

Astronomers have used the @almaobs to directly study how stars begin forming in another galaxy for the first time, moving beyond the Milky Way into the Large Magellanic Cloud. The key advance is that they were able to measure the so-called core mass function, which describes the distribution of dense gas clumps that will eventually collapse into stars, essentially capturing the earliest observable stage of star formation. By pushing ALMA to extremely high angular resolution, the team resolved structures only a few thousand astronomical units across and identified more than 70 dense cores embedded in protoclusters within the 30 Doradus region. These observations were carefully validated using complementary data from the Hubble Telescope and the #JWST to ensure the detected objects are genuinely young, still-forming structures rather than ionized gas contamination. What makes the result particularly important is that, despite the Large Magellanic Cloud having very different physical conditions compared to the Milky Way, including lower metallicity, stronger radiation fields, and a more turbulent interstellar medium, the distribution of these cores follows the same statistical behavior seen in our own galaxy and is consistent with classical expectations such as Salpeter-like scaling. This indicates that the initial fragmentation of molecular clouds into dense cores, which sets the stage for star formation, may be governed by universal physics that does not strongly depend on the broader galactic environment. At the same time, later stages may still diverge, since such environments can produce relatively more massive stars, suggesting that while the “starting conditions” are similar, subsequent growth and evolution can differ. In practical terms, this work opens a new observational regime: astronomers can now study the earliest phases of star formation in other galaxies with the same level of detail previously restricted to the Milky Way. That allows direct testing of whether star formation laws are truly universal or vary across cosmic environments, providing a bridge between local star formation studies and the conditions that dominated the early universe. 👉 nature.com/articles/s4146…

Astronomers using @almaobs 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. public.nrao.edu/news/3i-atlas-…

🙌🏻Our second day at the Science Walk in @puertodeideas Chile

It is with great sadness that we announce the passing of Thijs de Graauw, Director of ALMA from 2008 to 2013. We extend our deepest condolences to his family, loved ones, and the entire scientific community, including his beloved Planetario Observatorio Ocoa.

📡We have 66 antennas, and they're movable! 😎 Unlike a telescope, which is built in one place and stays there, we move the antennas using specially designed transporters to relocate them and adapt to the needs of observing the cosmos. 📹: Y. Villalón, ALMA Photo-ambassador

Only one chance in this lifetime… Like watching sunset at the beach from the most foreign seat in the cosmos, I couldn’t resist a cell phone video of Earthset. You can hear the shutter on the Nikon as @Astro_Christina is hammering away on 3-shot brackets and capturing those exceptional Earthset photos through the 400mm lens. @AstroVicGlover was in window 3 watching with @Astro_Jeremy next to him. I could barely see the Moon through the docking hatch window but the iPhone was the perfect size to catch the view…this is uncropped, uncut with 8x zoom which is quite comparable to the view of the human eye. Enjoy.
