📡ALMA and VLA📡 @TheNRAO, Reveal Signs of a Companion Stirring Betelgeuse’s Atmosphere.
The companion star is known as Siwarha.

✨Supernova explosions in this galaxy would have spread heavy elements forged inside stars, like oxygen, which has been now detected with the ALMA.

📡At Chajnantor, exploring the cosmos means working in extreme conditions.
🫡Our team knows this firsthand.
Here, ALMA staff clear snow from the roads and check the antennas, keeping the observatory ready to explore the Universe.

🙌🏻On this day 23 years ago, the first stone was laid for the construction of the ALMA observatory.
✨ALMA officials and partners gathered on the Chajnantor Plateau, at an altitude of 5,000m in the Atacama Desert, the site where ALMA installed its 66 antennas.

Finally, the "Astro Gull" 🪶
One of our neighbors on the Chajnantor Plateau in Chile is the Andean Gull.
Have you heard of it?

📡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.
🙌Good morning!

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.
