Nebulas

What is a nebula?

A nebula is a vast cloud of gas and dust in space, often the birthplace of stars.

Types of nebulas

The main types of nebulas are emission, reflection, and dark nebulas.

Emission nebula

An emission nebula is a cloud of ionized gas that emits light of various colors.

Reflection nebula

A reflection nebula is a cloud of dust that reflects light from nearby stars.

Dark nebula

A dark nebula is a dense cloud of gas and dust that blocks light from objects behind it.

Famous nebula: Orion Nebula

The Orion Nebula is one of the brightest and most studied nebulas, located in the Orion constellation.

Hubble Space Telescope and nebulas

The Hubble Space Telescope has provided significant insights and stunning images of various nebulas.

Planetary nebula

A planetary nebula is formed when a star sheds its outer layers at the end of its life cycle.

Supernova remnants

Nebulas formed from the explosive remnants of a supernova are known as supernova remnants.

Role of nebulas in star formation

Nebulas provide the necessary material for star formation, collapsing under gravity to form new stars.
