First gravitational-wave detection is announced

Gond astronomy continues to change, and researchers must avoid treating communities as frozen remnants of the past.

The spacecraft made humanity’s first close flyby of the dwarf planet.

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.

The announced result opened observational astronomy using ripples in spacetime.

The collaboration explained how two detectors had measured the same astrophysical signal.

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.
