Space Science
Subject: Physics | Topics:

Principle purpose of this lecture is to present on Space Science. Space Science includes Galaxies, Multiple Star Systems; Constellations; Spectroscope Lab; Toilet Paper Solar System Lab; Characteristics of Stars; H-R Diagram
Measuring Star distances (parallax); The Sun: Our special Star; Activities of the Sun etc. Here briefly describe on Absolute Magnitude. Absolute Magnitude is the star’s actual brightness. Apparent Magnitude is how bright a star appears from Earth. The H-R Diagram is based on the actual brightness of a star. If we place two stars were the same distance from the Earth, and measured their brightness, this would be their absolute magnitude.
