What are noesis and noema in Husserl’s phenomenology?

In Edmund Husserl’s phenomenology, the concepts of noesis and noema are essential to understanding the structure of intentional experience, which is the directedness of consciousness toward an object.1

• Noesis refers to the subjective aspect of an intentional experience; it is the act of consciousness itself, such as perceiving, imagining, or judging.12
• Noema refers to the objective aspect or the content within that intentional experience—the entity as it is intended or "meant" by the conscious act.31

Husserl’s goal in phenomenology was to discover the essential structures of these acts (noesis) and the corresponding objective entities (noema) that are constituted within them. By analyzing these components, phenomenology seeks to understand how meaning is founded and constituted within consciousness, treating these phenomena as absolute data accessible through pure, immanent intuition.1
