Vernal Equinox: Google marks the day with stop-motion animation doodle

Internet giant Google celebrates the Vernal Equinox or the first day of spring in the northern hemisphere with the day and night durations being equal. Thereafter, the days start becoming longer in the northern hemisphere of the earth.

The doodle on Google's homepage welcomes the springtime this year by depicting a lovely line of flowers of different bright colours that grow in size and bloom before a bumblebee lands in the middle to collect pollen in stop-motion animation format.

In stop-motion animation technique the picture frames are consist of physically manipulated object to make it appear to move on its own. In other words, the object is moved in small increments between individually photographed frames while being photographed sequentially. This creates an illusion of movement when the series of frames are played as a continuous sequence.

The word equinox is derived from the Latin aequus (equal) and nox (night). In the northern hemisphere, an observer sees daylight before the first glimpse of the Sun's disk above the horizon. According to scientists, on this day in March, the sub-solar point crosses the equator to move northward.

Since On the equinox, the center of the Sun spends a roughly equal amount of time above and below the horizon of the Earth, therefore, both the night and day is about the same length.

Coincidently, on Vernal Equinox this year includes a solar eclipse and a supermoon in some parts of the world.
