Black-hole merger enters public scientific record

Cameras and instruments collected data on Pluto during the encounter; transmission to Earth continued afterward.

The mission studied Pluto and its large moon Charon during the same close encounter.

The flyby transformed Pluto from a distant point into a world with visible geological features.

LIGO scientists reported a signal from merging black holes recorded on 14 September 2015.

The announced result opened observational astronomy using ripples in spacetime.

The LIGO spokesperson helped present a discovery produced by a large international collaboration.

The publication examines how celestial motion, songlines and landscape knowledge support travel and orientation.

Routes can be encoded through sequences of places, stories and sky references rather than written charts.

Eclipses, meteors and other striking phenomena may be remembered through narratives that preserve observational details.

The review argues that Indigenous knowledge should be engaged respectfully in teaching rather than appended as folklore.
