## In brief

- Researchers report a likely supermassive neutron star in a remarkably wide binary system.
- The findings were published in Science Advances, Volume 12, Issue 46, November 2026.

## Why it matters

Supermassive neutron stars are a rare and theoretically debated class of compact object, so a candidate in a wide binary offers a concrete case for testing ideas about how such stars form and persist.
