Galactic Center — central region of the Milky Way, hosting the supermassive black hole Sgr A* and an extreme density of stars.
Relevance to UAP / SETI
The Galactic Center is a strategic SETI target because:
- Stellar density maximizes the line-of-sight count of potentially habitable systems within a single telescope beam.
- It would be a natural beacon site for a galaxy-spanning civilization seeking to transmit to the widest stellar population.
Vault use
- BLIPSS (Cornell/SETI Institute/Breakthrough Listen) targets the Galactic Center at 4–8 GHz with the Green Bank Telescope for periodic spectral signals (src-seti-galactic-center-search-2025-07).
- The Sardinia Radio Telescope high-frequency survey (Manunza et al. 2025) observed the Galactic Center at 6 GHz and 18 GHz — the first SETI search at 18 GHz — returning a null result (src-sardinia-technosignature-search-2026-05).
