Galaxy in a Middle of a Cosmic Void Should Not Be Possible
Bizarre Activity in Isolated Void Galaxy NGC 6789
Discover why the ancient galaxy NGC 6789 is forcing astronomers to rethink galactic evolution models by demonstrating vigorous star formation deep within an empty cosmic void, contradicting traditional merger-based theories.
Short Summary
- Outcome: Scientists uncovered recent, massive star formation in NGC 6789, challenging the expectation that void galaxies remain "fossil" relics.
- Why it Matters: This activity suggests a new mechanism—cold gas accretion directly from the void—is fueling stellar growth, rather than relying on galactic collisions.
- Discovery Context: Deep optical imaging bypassed previous survey limitations to reveal the sudden starburst activity in this highly isolated galaxy.
- Future Insight: Studying these galaxies offers a rare, direct glimpse into the pristine gas interactions that likely dominated the very early universe.
This information details the perplexing case of NGC 6789, a galaxy located in the Local Void, which experienced a significant starburst recently. We examine the observational evidence ruling out mergers and explore the leading theory: steady inflow of elemental gas directly siphoned from the surrounding near-empty space.

There is something simultaneously comforting and frightening in the idea of a galaxy sitting in the middle of the void like this. Thank you Anton for bringing the wonders of the universe to my screen every evening.
And yet, there it is.
One thing I’ve learned by making it to the 2020s is that what we think space should be doing isn’t close to what space is actually doing
The aliens moved their galaxy into the void for safety.
in all fairness to the models they're just models. it's not expected that they're going to cover every possible circumstance that could occur in this fast universe
Wonderful as always Anton. Thank you. 😸
I've been working out a story universe concept where this type of galaxy exists. Thank you so much for validating it.
