Humongous Bubble Around a Distant Star That Currently Makes No Sense
Bizarre Supergiant Star DFK 52 Reveals Unprecedented Circumstellar Structure in Milky Way
Discover why the seemingly ordinary red supergiant DFK 52 possesses an enormous, complex gaseous envelope that dwarfs even extreme stellar examples, challenging current models of stellar evolution.
Short Summary
- ALMA observations revealed DFK 52 is shrouded in a massive bubble of gas and dust, stretching 50,000 AU in radius—up to 63 times larger than the envelope of VY Canis Majoris.
- The structure suggests a massive, dramatic mass-loss event occurred approximately 4,000 years ago, yet the star has not yet undergone a supernova.
- The specific double-peaked spectrum and lack of central emission point toward cold, detached molecular components, possibly caused by a stellar merger or common envelope event.
This discussion details the unusual ALMA findings regarding DFK 52, a red supergiant in the Stevenson 2 cluster, focusing on its extreme size, chemical composition, and what this implies for predicting massive star death events.

Aliens caught our TV signals and decided to put up a shield to block it out.
As an alien we’ve been listening to you and respectfully ask that when we arrive, please don’t take us to any of your leaders. We don’t like them.
Modern telescopes are amazing. I wonder what the next generations will bring.
The more we learn the more we realize we still have so much more to learn.
to all commenters saying its a dyson swarm/sphere: its not a dyson swarm/sphere, if it was then it would not be around a star at the end of its lifetime when there's way more efficient stars for a dyson swarm, unless the alien civilization is stupid then it wouldn't build a dyson swarm around a red giant.
Wow, I'm here early! Hi Anton! I've been wanting to tell you how much I appreciate you bringing truth and love to us all! I will support you as long as I am able❤. God bless you!❤
The thing about astronomy. There's plenty of work, but the pay is wanting.
Thanks Anton, I really enjoy your videos.
Wonderful as always Anton
It's worth mentioning that the entire parent cluster is obscured from view in the visible light band by dust and gas.
