Hulse and Taylor: discovery of a pulsar in a binary system

What changed

Discovered and initially characterized PSR 1913+16 as a binary pulsar.

Scientific scope

The record is the exact two-author 1975 discovery report. It remains separate from later timing evidence for orbital decay and does not absorb all binary-pulsar observations or relativistic interpretation.
