10 Amazing Desert Landscapes

Some of the most interesting landscapes in the world are in the most desolate, dry regions of the world. From magnificent sand dune fields and vast expanses of sun-reflecting salt to gargantuan rock formations. As deserts cover almost one third of the Earth’s land surface this list features only a tiny selection of these amazing desert landscapes.

Valle de la Luna is located in the Atacama Desert in Chile. This breathtaking desert landscape is the result of centuries of winds and floods on the sand and stone of the region. The large sand dunes and stone formations mimic the surface of the moon, giving the region its name, which translates to “Valley of the Moon”. The unique color of the landscape, caused by the way the salt formations reflect the sunlight, makes the Valle de la Luna a beautiful, changing spectrum of bright blue, green, yellow and red colors.

The Pinnacles Desert is in the Nambung National Park in Western Australia. Its unusual finger-like limestone formations among vast sand dunes create a strange, mystical appearance. With the movement of the sun, these formations cast eerie shadows across the desert. Surrounding wildflowers enhance the desert’s beauty from August to October.

McMurdo Dry Valleys

With an annual perception of only 200 mm (8 inches) along the coast an even less inland, Antarctica is considered the largest desert on Earth. Antarctica’s most extreme desert region is the McMurdo Dry Valleys. Even though the Valleys are nestled in an ice-covered continent, they have have been ice-free for thousands of years. The harsh katabatic winds blow through the desert at speeds of up to 320 km (200 miles) per hour with a force capable of evaporating all moisture. Consequently, the McMurdo Dry Valleys are considered to be the earth’s closest equivalent to the surface of Mars.

Death Valley

Death Valley is an imposing, diverse landscape that stretches across parts of Nevada and California. It is known as the lowest, driest, and hottest location in North America. Death Valley has recorded temperatures as high as 130 degrees. From snow-capped mountains to colorful sand dunes, the unique desert landscapes of Death Valley are like no other place in the United States. Places of interests include the scenic area of Zabriskie Point and the mysterious moving stones of Racetrack Playa.

Located along Egypt’s border with Israel , the Sinai Desert is a major tourist destination due to its religious history, and it’s scenic beauty. The rugged mountain contrasting with golden sand and blue skies offer the visitor spectacular views of the desert. The Sinai Desert branches out to join the beaches of the Red Sea, where the amazing diving waters are known world-wide.

Erg Chebbi

The Erg Chebbi dunes are located in the Sahara Desert in Morocco. The awe-inspiring dunes are as high as 150 meters tall, and one certainly feels small in their shadows. Excursions to the dunes normally start from the village of Merzouga which is located on the edge of the erg. Camel trekking is the most popular option although it isn’t the most comfortable way of traveling.

Sossusvlei
Sossusvlei
Sossusvlei is a enormous clay pan surrounded by gigantic, red sand dunes, and it is located in the Namib Desert of Namibia. The Tsauchab River flows through the desert, and its rare flooding waters the vegetation that survives in the clay soil. During sunrise and sunset, the colors of the sand dunes are constantly changing and provide an opportunity for photographers. The fierce desert winds continually alter the shape and texture of the dunes, providing an ever-changing desert landscape.

Nazca Desert

The Nazca Desert occupies a strip along the northern Pacific coast on a high arid plateau. The famous Nazca Lines are located between the towns of Nazca and Palpa. Created between 200 BC and 700 AD the figures range from simple lines to stylized spiders, monkeys, fish, llamas, lizards and human figures. The lines were created on such a large scale that it wasn’t until the 1920’s, when Peruvian airlines started to fly from Lima to Arequipa, that the lines were recognized as figures. The dry, windless, stable climate of the Nazca Desert has helped keep the lines uncovered to the present day.

Wadi Rum

Located in the Andes Mountains of Bolivia, Salar de Uyuni is the largest salt flat in the world. The expanse of salt creates an unending white landscape during the dry season, but the area is most breathtaking in the rainy season when it is covered in water. The reflection of the blue sky creates an even more surreal landscape although some people insist on seeing the salt.

What is the Interstellar Medium?

Simply put, the interstellar medium is the material which fills the space between the stars. Many people imagine outer space to be a complete vacuum, devoid of any material. Although the interstellar regions are more devoid of matter than any vacuum artificially created on earth, there is matter in space. These regions have very low densities and consist mainly of gas (99%) and dust. In total, approximately 15% of the visible matter in the Milky Way is composed of interstellar gas and dust.

The heliosphere is a bubble in space "blown" into the interstellar medium (the hydrogen and helium gas that permeates the galaxy) by the solar wind. Although electrically neutral atoms from interstellar space can penetrate this bubble, virtually all of the material in the heliosphere emanates from the Sun itself.

For the first ten billion kilometres of its radius, the solar wind travels at over a million kilometres per hour.As it begins to collide with the interstellar medium, it slows down before finally ceasing altogether.

The point where the solar wind slows down is the termination shock; the point where the interstellar medium and solar wind pressures balance is called the heliopause; the point where the interstellar medium, travelling in the opposite direction, slows down as it collides with the heliosphere is the bow shock.

WILDLIFE PROTECTION SOCIETY OF INDIA (WPSI)

Tiger in South IndiaImage via Wikipedia
The WILDLIFE PROTECTION SOCIETY OF INDIA (WPSI) was founded in 1994 by Belinda Wright, its Executive Director, who was an award-winning wildlife photographer and filmmaker till she took up the cause of conservation. From its inception,

WPSI's main aim has been to bring a new focus to the daunting task of tackling India's growing wildlife crisis. It does this by providing support and information to government authorities to combat poaching and the escalating illegal wildlife trade - particularly in wild tigers. It has now broadened its focus to deal with human-animal conflicts and provide support for research projects.
