Wisdom Wednesday #3: What is a Star Chart?
<p>A star chart, also known as a star map, is a map of the night sky that astronomers use <strong>to identify and locate astronomical objects such as stars, constellations, galaxies and planets</strong>. It is a fundamental tool in celestial navigation and has been used since ancient times to aid in the understanding and organization of the cosmos.</p>
