Question 3
3.1 Define the Milky Way Galaxy
The Milky Way Galaxy is a large spiral galaxy containing our solar system appearing
as a hazy band of light that we see from Earth at night. Stars (100 billion to 400
billion) so small and closely grouped together make up this hazy band as they can
not be individually identified by the naked eye.
3.2 Differentiate between equinox and solstice.
Equinox: Time when daylight and night-time are more or less the same in length, In
the Northern hemisphere this occurs twice a year in the spring and autumn. This is
when the plane of the Earth’s equator passes through the centre of the suns disc.
Spring equinox marks the beginning of the astronomical spring with longer days as
daylight will be longer than night-time. Autumn equinox marks the start of autumn as
nights become longer than days in terms of light.
Solstice: Occurs on the longest and shortest days in terms of sunlight and marks
the summer and winter seasons, this occurs when the sun reaches the highest or
lowest point in the sky around noon. The summer solstice occurs when the Northern
hemisphere is tilted towards the sun resulting in increased sunlight and therefore
warmer temperatures. The winter solstice will thus be when the sun is at its lowest
point resulting in lower temperatures as sunlight is decreased.
