What the video shows, in words

A silent 45-second explainer drawn with the site’s own all-sky chart: the whole sky over Georgetown, Guyana, from sunset to sunrise on the night of Saturday 10 to Sunday 11 October 2026, a new-Moon night. The zenith is in the middle and the horizon at the rim; east is on the left, as the sky looks when you lie back with your head to the north. Stars are drawn to magnitude 4.6.

Twilight: sunset 17:40, end of civil twilight 18:01, nautical 18:25, astronomical (full dark) 18:49; dawn begins 04:30, civil dawn 05:18, sunrise 05:39, all GYT. 9.7 hours of full dark. The Moon is new: it sets at 17:38, with the Sun, and rises at 06:15, after sunrise, so it never lights the night.

Planets: Mercury sets 19:05 GYT (west-southwest); Venus sets 18:36 GYT (west-southwest); Mars rises 01:02 GYT (east-northeast); Jupiter rises 01:59 GYT (east-northeast); Saturn rises 17:15 GYT (east) and sets 05:20 GYT (west).

Computed with astronomy-engine for Georgetown (6.80° N, 58.16° W); times are Guyana time (UTC-4).
