2. An aurora (Latin word mean “sunrise”) is
natural light display in the sky in the poles
(north and south) caused by the collision of
energetic charged particles with atoms in the
high altitude atmosphere

3. The aurora phenomenon occurs when the
sun produces solar wind. a fast-moving
stream of particles constantly flowing from
the Sun that bring out the Sun’s magnetic field
out into the space. The solar wind is typically
moving at 250 miles (400 kilometers) per
second, molds in into an elongated bubble or
cavity and flow past Earth’s magnetic field,
compressing sunward side and stretching its
night side far beyond the Moon’s orbit.

4. Because the collision between these
particles and atoms present in the earth’s
atmosphere, it releases the energy that
causes the formation of colorful auroras
at the poles of the earth, which looks like
a big circle around the pole.

5. Why Aurora is only found in the earth’s poles??
Because the north and South Pole magnetic
field is very strong compared to other regions.
So the phenomenon is more common in the
Polar Regions.

6. Aurora Coloured light in the night sky near the
Earth’s magnetic poles, called aurora borealis
(northern lights) in the northern hemisphere
and aurora australis (southern lights) in the
southern hemisphere.

7. However, sometimes the Aurora can also
appear at the top of the mountain in a
tropical climate, but this phenomenon is
extremely rare.
