MeerKAT is inaugurated in South Africa

The combined observations connected gravitational waves with light from the same distant event.

The article explains how moving plates and engraved scales model the visible sky for particular latitudes.

Users could solve problems involving stars, sunrise, direction, calendars and the hours of prayer.

Metalworking, calligraphy, geometric design and numerical tables were all necessary to produce a reliable instrument.

They expanded astrolabe theory, manufacture and uses before the instrument circulated further through Africa, Asia and Europe.

The observatory unveiled a striking radio image of the central region of our galaxy.

The inauguration marked a major South African contribution to global astronomy.

The array became a precursor to the wider Square Kilometre Array observatory.

The publication presents astronomy as a product of exchange among Chinese, Indian, Persian, Greek, Arab and Central Asian traditions.

Scholars compared inherited tables and models rather than simply copying them, producing new observations and calculations.
