Finally, the "Astro Gull" 🪶 One of our neighbors on the Chajnantor Plateau in Chile is the Andean Gull. Have you heard of it? 📷: @_ansack, ALMA Photo-ambassador.

🫡My current status✅ 📡We recently revealed the irregular surface of Betelgeuse, the famous red supergiant in the constellation Orion. ⭐️The observations show bright hot spots and an irregular, corrugated outline, shaped by the enormous movements taking place inside the Star.

NEW: What Lurks Within the Shadows of Betelgeuse? Betelgeuse, Betelgeuse, Betelgeuse … 👻 You can say it three times, but new data (NSF VLA and @almaobs) suggests that its recently discovered companion star, Siwarha, is the one doing the haunting. public.nrao.edu/news/what-lu…
What Lurks Within the Shadows of Betelgeuse?

What Lurks Within the Shadows of Betelgeuse?

New VLA and ALMA radio images show Betelgeuse’s companion star Siwarha perturbing the red supergiant’s atmosphere as it orbits through it.

🙌🏻“ALMA Open House in San Pedro de Atacama, Chile” — it’s a wrap! It had been 7 years since we last hosted public visits, and nearly 160 people took part across these two special events. 🙂Would you like to see public visits return? Let us know in the comments!

Using @almaobs 's sharpest observations, astronomers have uncovered rings and gaps in compact disks, raising new questions about how planets form close to young stars. techexplorist.com/tiny-plane…

📡 We reveal planet-forming structures in small disks. 📷: 11 compact disks of planet formation in the Lupus region. The comparison illustrates planet formation at distances comparable to those of our own solar system. almaobservatory.org/en/press…
ALMA images of the 11 compact planet-forming disks observed in the Lupus star-forming region. Using the highest angular resolution available with ALMA at a wavelength of about 0.9 millimeters, astronomers revealed previously hidden structures in several of these small disks. The lower-right panel shows the orbits of Earth, Mars, Jupiter, and Saturn, together with the asteroid belt, for scale. The comparison illustrates how these observations probe planet formation at distances comparable to those within our own Solar System. Each white scale bar represents two astronomical units; one astronomical unit is the average distance between Earth and the Sun. Credit: P. Curone et al. – ALMA (ESO/NAOJ/NRAO)
