The Sky Down Under - Our Visit to the Southern Hemisphere<\/b><\/a><\/font>

Standard Time<\/b><\/a><\/font>
In the modern world, we use "Standard Time" in which the whole world is divided into 24 time zones. As a result, on any day of the year at any latitude, the times of actual sunrise and sunset vary depending on your location within a time zone.<\/font><\/a><\/font><\/td><\/tr>
Latitude and Declination<\/b><\/a><\/font>
On the Earth, we measure position on the globe by the coordinates of latitude and longitude. Latitude measures position from North to South. In the sky, celestial positions are given in coordinates of "Declination" and "Right Ascension." <\/font><\/a><\/font><\/td><\/tr><\/table>');
