Nebulae
Cosmic Clouds of Gas and Dust
Nebulae are vast clouds of gas and dust in interstellar space. They are some of the most beautiful objects in the universe and serve as stellar nurseries where new stars are born. Some nebulae are formed by dying stars.
Types of Nebulae
- Emission Nebulae: Glow due to ionized gas (e.g., Orion Nebula)
- Reflection Nebulae: Reflect light from nearby stars
- Dark Nebulae: Block light from objects behind them
- Planetary Nebulae: Formed by dying stars shedding outer layers
- Supernova Remnants: Debris from exploded stars
The Orion Nebula
The Orion Nebula (M42) is one of the brightest nebulae visible to the naked eye, located about 1,344 light-years away. It is a stellar nursery where new stars are actively forming from the collapsing gas and dust.
Pillars of Creation
The Pillars of Creation are iconic columns of gas and dust in the Eagle Nebula. First photographed by the Hubble Space Telescope in 1995, they contain young stars in the process of formation.
