Ever since you read the name 'Twilight' automatically Stephnie Mayors cast and characters come to your minds.

The cullen family(vampires) and the love for edward from bella were the notable scenes which pop our minds.But the fact of the season is typically an enjoyable one which one wants to know the facts of this period.

Twilight is a period between dawn and sun rise or between Dusk and sunset.

Twilight on Earth is the illuminationof the lower atmosphere when the Sun itself is not directly visible because it is below thehorizon. Twilight is produced bysunlight scatteringin the upper atmosphere, illuminating the lower atmosphere so that Earth's surfaceis neither completely lit nor completely dark. The word twilight is also used to denote the periods of time when this illumination occurs.

There are Three types of Twilight.

Astronomers recognize three kinds of twilight.

  • During civil twilight the brightest planets, such as Venus, appear.

  • Nautical twilight ends when the horizon is no longer visible at sea, and astronomical twilight ends when there are no traces of sky glow left.

It's hard to distinguish astronomical twilight from true night, but if you're looking for nebulae or galaxies, it's better to wait until night has officially started.

After reading this article I hope the readers would definitely see Twilight and would experience the science behind it.

This time of day is important for a lot of reasons to many people – for example, astronomers, who are waiting for true darkness to fall so they can begin their observations. So some more strict definitions have evolved on the subject of twilight.
