The universe is full of phenomenon that are beyond the imagination of humans. People travel to great distances just to get a glimpse of these spectacular sites. These natural processes are a site to behold.

NORTHERN and SOUTHERN LIGHTS

Aurora borealis and aurora australis, named after the Roman goddess of dawn, are glows in the sky over lower artic and antarctic regions. In the arctic region they are known as aurora borealis or the northern lights and in the antarctic region, known as aurora australis or Southern lights. This phenomenon is formed when the highly charged electrons from the solar winds collide with the earth’s atmosphere. Lights of green, blue, red or violent color are formed, depending upon which atom strikes the wind at which altitude. It appears like long curtains dancing in the sky. There are sometimes referred to as polar lights since, they occur near the north and south pole.

SUN HALOS

It is an optical phenomenon produced by light when it interacts with the ice crystals suspended in the air. It occurs with the light from sun and moon, where sun halos being a rare one, also known as 22 degree halo. The ice crystals act as prisms bending and reflectithe light. There is a saying “ring around the moon means rain soon” which is somewhat true since the sun halos are formed in cirrus clouds which indicate low pressure system and might bring rain or snow in a few days. Though it is advised to avoid looking directly at the sun through them as it might damage the eyes.

BIOLUMINESCENT SHORES

Bioluminescence is the production and emission of light by a living organism. Thanks to some creatures in water we can witness glowing stars like phenomenon near water shores. The sparkles can be of neon blue, green or red color. Some fish, squid, tiny crustaceans and algae produce bioluminescent lights to confuse predators or lure potential mates. We can witness this phenomenon where there is large amount of bioluminescent creatures, usually algae bloom of plankton. The sea glows when it is disturbed by a wave or splashes at night, in simple words planktons emit light when disturbed.

LIGHTNING

The imbalance between storm clouds and the ground causes an electrical discharge known as lightning. The colliding particles often cause the imbalance and the lower of clouds becomes negatively charged which is drawn by the positively charged particles like trees and earth itself. The lightning is too hot and can make the atmosphere around it 5 times hotter than the sun’s temperature. Hence, it is advised to remain indoors when there is storm outside as the lightning can stike anywhere.

BLOOD MOON

A total lunar eclipse is known as blood moon because of the red tint it acquires after full eclipse. This term is also used to describe the 4 total lunar eclipses in a row. It occurs when some of the sun light reaches the moon’s surface indirectly giving the moon a reddish, orange or yellow glow. Lunar tetrads (4 lunar eclipses) are a rare phenomenon and hence they may be of religious importance to some people.
