Antarctica, the southernmost continent, is one of the most mysterious and inhospitable places on Earth. It is covered by ice and is the coldest, driest, and windiest continent. But when was this frozen landmass first discovered by humans?
The existence of Antarctica was known to the ancient Greek philosophers, who theorized about the existence of a large landmass in the southern hemisphere to balance out the known lands in the north. However, it wasn’t until the late 18th century that explorers started to confirm the existence of this icy continent.
The first confirmed sighting of Antarctica is credited to the Russian explorer Fabian Gottlieb von Bellingshausen and his crew on January 27, 1820. They spotted an icy shoreline and mountains near the Antarctic Peninsula, making them the first humans to lay eyes on this frozen wilderness.
The Discovery of Antarctica
Antarctica, the southernmost continent on Earth, was not officially discovered until the 19th century. However, there are records indicating that various explorers may have sighted parts of the continent as early as the 16th century.
The first confirmed sighting of Antarctica is attributed to the Russian expedition led by Fabian Gottlieb von Bellingshausen and Mikhail Lazarev in 1820. They circumnavigated the icy landmass and claimed it for Russia.
Several years later, in 1838, the United States Exploring Expedition, led by Charles Wilkes, conducted a thorough survey of the area and proved that Antarctica was indeed a separate continent.
However, it wasn’t until the early 20th century that explorers and scientists began to make significant discoveries about Antarctica. The famous British explorer Robert Falcon Scott led the first Antarctic expedition in 1901-1904, followed by Ernest Shackleton’s iconic Endurance expedition in 1914-1917.
These early expeditions laid the foundation for further scientific research and exploration of Antarctica. Today, Antarctica is a major focus of international scientific cooperation, with numerous research stations and expeditions conducted by various countries.

The First Recorded Sighting
The first recorded sighting of Antarctica is attributed to the ancient Greeks. Although they did not explore or land on the continent, they did mention the existence of a landmass in the southern hemisphere. The philosopher Aristotle, writing in the 4th century BC, speculated about the existence of a great southern landmass, which he referred to as “Antarktikos”. However, it wasn’t until the 18th century that the first confirmed sightings of Antarctica were made by European explorers.
The first recorded sighting by an European explorer is credited to the Russian expedition led by Fabian Gottlieb von Bellingshausen and Mikhail Lazarev. In 1820, while on a circumnavigation of the globe, the expedition sighted the continent on January 28th. They observed the icy coastline of Antarctica, making note of its vast ice shelves and dramatic landscapes.
The discovery of Antarctica had far-reaching consequences. It sparked a race among explorers from different nations to be the first to reach the South Pole. It also led to the establishment of scientific research stations on the continent, where researchers study the unique climate and ecosystem of Antarctica.
James Cook’s Exploration
James Cook, a renowned British explorer, played a significant role in the exploration of Antarctica. He embarked on his first voyage to the South Atlantic and Pacific Oceans in 1768, with the primary goal of observing the transit of Venus. During this expedition, Cook circumnavigated New Zealand and made several important discoveries in the Pacific region.
Cook’s second voyage, which took place from 1772 to 1775, was dedicated to exploring the Southern Ocean and reaching the Antarctic Circle. His ship, the HMS Resolution, became the first to cross the Antarctic Circle in 1773. Cook and his crew continued to sail south, making multiple attempts to find land, but were ultimately unsuccessful in reaching Antarctica.
In 1779, Cook embarked on his third and final voyage, during which he made his closest approach to Antarctica. While exploring the Pacific region, Cook crossed the Antarctic Circle once again and sailed further south than any person had before. However, he was still unable to spot the continent itself.
Cook’s expeditions made significant contributions to the knowledge and charting of the Southern Ocean and surrounding regions. His accurate mapping of Pacific islands and determination of their longitudes greatly aided future explorers in their journeys. Although Cook did not directly discover Antarctica, his voyages laid the foundation for future explorations and scientific expeditions to the continent.
Antarctica in the 19th Century
The 19th century was a significant period in the exploration and discovery of Antarctica. Many expeditions were launched during this time, with explorers navigating treacherous seas and harsh conditions to uncover the mysteries of the southernmost continent.
One of the first notable expeditions to Antarctica in the 19th century was the British expedition led by James Clark Ross. In 1841, Ross sailed to the Antarctic region and navigated through the icy waters, mapping significant parts of the coast and discovering many of the islands surrounding the continent.
Another significant explorer of the time was Carsten Borchgrevink, who led the British Antarctic Expedition in 1898. This expedition marked the first documented landing on the continent, with Borchgrevink and his team spending a winter in Antarctica and conducting scientific research.
The 19th century also saw the famous expedition led by Robert Falcon Scott. In 1901, Scott’s expedition, known as the Discovery Expedition, set out for Antarctica with the goal of scientific research and exploration. The expedition established a winter station in Antarctica and made numerous discoveries, including the existence of the South Magnetic Pole.
Throughout the 19th century, many other explorers and scientists ventured to Antarctica, contributing to our knowledge of the continent. They faced extreme weather conditions, dangerous ice formations, and limited resources, yet their efforts laid the foundation for future explorations and scientific studies in Antarctica.
Race to the South Pole
One of the most thrilling and daring adventures in history was the race to the South Pole. Taking place in the early 20th century, this race involved two rival parties from different countries, each dreaming of being the first to reach the southernmost point on Earth.
The race began on the 1st of November, 1911, when Norwegian explorer Roald Amundsen and his team set out from their base camp. Amundsen’s preparations for the journey were meticulous, with careful planning and attention to detail. He had equipped his team with specially designed sleds and trained his dogs to endure the harsh conditions of Antarctica.
Amundsen’s main rival in the race was British explorer Robert Falcon Scott. Scott embarked on his journey to the South Pole a month later, on the 1st of December, 1911. Unlike Amundsen, Scott relied heavily on motorized sleds, which proved to be unreliable in the extreme cold of Antarctica.
The two parties faced numerous challenges on their treacherous journey. Bitter cold, blizzards, and dangerous crevasses tested their endurance and determination. As the race progressed, it became evident that Amundsen had a significant advantage. His meticulous planning paid off, and his team reached the South Pole on the 14th of December, 1911, becoming the first humans to set foot on this remote and inhospitable continent.
Unfortunately for Scott and his team, they reached the South Pole on the 17th of January, 1912, only to discover that Amundsen had beaten them by over a month. Tragically, Scott and his party perished on their return journey, succumbing to the harsh conditions and lack of supplies.
The race to the South Pole was a testament to the indomitable human spirit and a milestone in the exploration of Antarctica. It marked the beginning of a new era of polar exploration and continues to inspire adventurers to this day.
