Antarctica is known as the southernmost continent, and it contains a geographic south pole with an area of 14,200,000 km. It is noted as the last region of the Earth in the recorded history to be discovered. The continent has largely been neglected for this hostile environment and lack of easily accessible resources and isolation. The continent provides avenues for scientific studies related to different fields. Thus, many countries have established research centres in Antarctica.
