Reaching for the Stars: Understanding "Astral" in Stellar Astronomy

The word "astral" evokes images of celestial wonder, of shimmering stars dotting the night sky. While often used poetically, "astral" holds a specific scientific meaning in the realm of stellar astronomy.

What Does "Astral" Mean in Astronomy?

In essence, "astral" simply means "relating to the stars". This term encompasses a broad range of celestial objects and phenomena, including:

• Stellar processes: The term "astral" applies to the activities within stars, such as nuclear fusion, stellar winds, and supernova explosions.
• Celestial bodies: Planets, comets, asteroids, and other bodies orbiting stars are considered "astral" objects, as their existence is tied to the presence of a star.
