What changed

Detected large-scale temperature anisotropy in the cosmic microwave background using the first-year COBE DMR maps.

Scientific scope

Detected large-scale temperature anisotropy in the cosmic microwave background using the first-year COBE DMR maps. Scope limitation: This is the DMR anisotropy result. The blackbody-spectrum measurement and later high-resolution missions are distinct.

Evidence

Assessment uses the catalogue-linked source evidence for the stated contribution. This is the DMR anisotropy result. The blackbody-spectrum measurement and later high-resolution missions are distinct.
