Two things:
1. The star is eclipsed by the Moon
2. In passing in front of a star by the Moon, the star is limned by the leading edge of the Moon and again by the trailing edge of the Moon.
The Matariki stars, part of the Pleiades star cluster, appear to "disappear" in late autumn as they become less visible in the night sky due to the changing position of the Earth in relation to the stars and the rising of the Sun. This phenomenon occurs as the stars are obscured by the Sun's light during the longer days of summer. Matariki, or the Māori New Year, is celebrated when the cluster reappears in the early morning sky, signaling a time for reflection and renewal.
Your shadow's position depends on the angle of the light source, primarily the sun. When the sun is low in the sky, such as during sunrise or sunset, your shadow is cast long in front of you. Conversely, when the sun is high overhead, your shadow falls directly beneath you or slightly behind you. This phenomenon occurs because shadows are formed in the direction opposite to the light source.
When sunlight is dispersed and reflected by water droplets, a rainbow forms. This phenomenon occurs due to the refraction of light as it enters and exits the droplets, splitting the light into its constituent colors. The resulting arc of colors is typically seen when the sun is behind the observer, and rain or mist is present in the opposite direction.
the time when the Moon sinks below the horizon
This phenomenon is called a "lunar sunrise." It occurs when sunlight illuminates the far side of the moon as seen from Earth.
The phenomenon is known as diffraction.
The spreading of waves into the region behind an obstacle is known as diffraction. This phenomenon occurs when waves encounter an obstacle or opening and bend around it, causing them to spread outwards into the shadow region behind the obstacle.
This occurs during telophase of mitosis.
Supernova.
The name of the phenomenon is refraction.
A biological phenomenon is a process or event that occurs within a living organism, involving physical and chemical aspects of the body. On the other hand, a psychological phenomenon refers to a mental or cognitive process that occurs in the mind, such as thoughts, emotions, or behaviors.
The change of state that occurs when a puddle disappears is evaporation. The liquid water in the puddle turns into water vapor and escapes into the air.
The process that occurs when light disappears in a medium and is converted to another form of energy is called absorption.
You must mean that Watson fainted for the first and last time in his life when Holmes reappears.

when shortage in the supply of products occurs, advertising often disappears into the background. eg. petroleum
The phenomenon of polarization occurs for transverse waves, such as light waves and electromagnetic waves.
