Light pollution is a human-made alteration of outdoor light levels from those occurring naturally. It has harmful effects on streetlights, greenhouses, and satellites, among other sources. To combat this, the International Dark Sky Places program certifies communities, parks, and protected areas around the world that preserve and protect dark sites through responsible lighting policies. Some of the best places to see the stars without light pollution include the Atacama Desert in Chile, the Little Rann of Kutch in India, the Andaman and Nicobar Islands, the Blue Mountains in Australia, and the western United States, including Big Bend National Park and Great Sand Dunes National Park.

What You'll Learn
The Atacama Desert in Chile
Light pollution is the human-made alteration of outdoor light levels from those occurring naturally. It has harmful effects on streetlights, greenhouses, and satellites, among other sources. The night sky is a heritage and a connection to our human past, and addressing light pollution is about maintaining that connection.
The Atacama Desert is also home to the Vera C. Rubin Observatory, which hosts an 8.4-meter telescope. This observatory will take images of the Southern Hemisphere sky over ten years to understand dark matter and energy, take an inventory of the solar system, and map the Milky Way. The Rubin Observatory is operated by NOIRLab, a United States government-funded program that operates two other facilities in the Atacama.
The Chilean government has recognized the importance of protecting the night sky in the Atacama Desert and has implemented regulations on outdoor lighting that dictate the direction, brightness, and color spectrum of lights. These regulations aim to protect astronomy, biodiversity, and human health.
Despite these efforts, the Atacama Desert's dark skies are still under threat. A proposed green-energy facility in Chile could increase light pollution and affect some of the most powerful telescopes in the world. Additionally, a proposed 3,021-hectare complex by a US energy company could increase light pollution by 10%.

The Little Rann of Kutch in India
The Little Rann of Kutch is a remote location, seeing few visitors. Devjibhai Ka Kooba, opposite the Little Rann of Kutch desert, is the only accommodation in the vicinity, making the nights there exceptionally dark. The winter months, from November to February, offer cool temperatures and clear skies, perfect for stargazing. During this time, the Milky Way rises a couple of hours before dawn, creating a stunning sight for astrophotographers and stargazers alike.
The Little Rann of Kutch is also known for its otherworldly terrain, shaped by tectonic shifts and climatic extremes. The Jatavira region, with its dried-up riverbed, offers a glimpse into the area's ancient past as part of a dynamic river system. The rock formations and sedimentary patterns in this region provide a unique landscape for nightscape photography.
In addition to its natural beauty, the Rann of Kutch holds cultural significance. It has served as a setting for scenes in Salman Rushdie's novel "Midnight's Children," and several Indian films. The area has been inhabited by the Kutchi people, and its name derives from the Sanskrit/Vedic word "iriṇa," meaning salt flat or barren ground.
The Little Rann of Kutch is a nature enthusiast's paradise, offering uninterrupted sessions under the stars and a window into the region's ancient geological history. Its remote location and minimal light pollution make it an ideal destination for stargazing and astrophotography, especially during the winter months.

The Andaman and Nicobar Islands in India
The Andaman and Nicobar Islands, a union territory of India, is an ideal destination for stargazers seeking pristine skies unspoiled by light pollution. This idyllic archipelago comprises 572 islands, of which only 38 are inhabited, offering an abundance of serene and dark skies. The islands are divided into two main clusters: the northern Andaman Islands and the southern Nicobar Islands, separated by a vast 150 km (93 mi) wide channel.
The capital and largest city of the territory, Port Blair, is located approximately 1,190 km (740 mi) from Chennai and 1,255 km (780 mi) from Kolkata on the Indian mainland. Veer Savarkar International Airport, near Port Blair, provides convenient access to the islands with regular flights to major Indian cities. The airport operates as a civil enclave, sharing facilities with the Indian Navy. Additionally, there are 23 ports across the islands, including a major port at Port Blair and significant ports at Diglipur, Mayabunder, Rangat, and Hut Bay, among others.
The Andaman and Nicobar Islands offer a unique blend of natural beauty and cultural richness. The white sandy beaches and lush green forests provide a peaceful backdrop for stargazing, with the azure waters of the ocean merging seamlessly with the colours of the night sky. Genetic and cultural studies suggest that the indigenous Andamanese people have a long history of isolation, dating back more than 30,000 years. The islands also boast a diverse linguistic landscape, with Hindi and English as the official languages, and major spoken languages including Bengali, Tamil, and Telugu.
For those seeking a truly remote and tranquil stargazing experience, the North Sentinel Island is home to the Sentinelese people, an uncontacted tribe. Additionally, the Nubra Valley in Ladakh, known for its zero light pollution, offers a peaceful camping experience under a sky full of stars. The Andaman and Nicobar Islands provide a magical setting for stargazers, with its untouched nature, rich cultural heritage, and dark skies offering a glimpse of the Milky Way.

The Thar Desert in India
India's Thar Desert, also known as the Great Indian Desert, is a vast expanse of arid land covering approximately 200,000 square kilometres in the country's northwestern region. Despite being a harsh and inhospitable environment with extreme temperature fluctuations, it is a fascinating place to visit, offering a unique and diverse range of flora and fauna. The desert is home to species such as the Indian wild ass, desert fox, and the great Indian bustard.
One of the best ways to explore the Thar Desert is by taking a camel safari, the traditional mode of transportation in the area. Camel rides allow visitors to traverse the dunes, experience the desert's immensity, and take in the stunning landscape views. The Thar Desert also boasts several historical sites and monuments, including the renowned 12th-century Jaisalmer Fort, a UNESCO World Heritage Site constructed from yellow sandstone. This fort exemplifies the exquisite architecture of Rajasthan and houses several palaces, temples, and havelis.
The Thar Desert is an ideal location for stargazing due to its clear skies and minimal light pollution. Visitors can witness the beauty of stars and constellations and, if lucky, even spot shooting stars. For those seeking a unique accommodation experience, the MANVAR Thar Luxury Desert Camp in Jaisalmer offers a range of activities, including camel safaris and jeep excursions, providing a comprehensive desert adventure.
However, it is crucial to be well-prepared when visiting the Thar Desert due to its challenging conditions. Staying hydrated and avoiding exposure to the sun during the hottest parts of the day are essential for a safe and enjoyable experience. Additionally, India as a whole struggles with light pollution, and it is not widely recognised as a form of pollution. Nevertheless, the Thar Desert remains a relatively untouched location for stargazing and offers a chance to witness the night sky in all its glory.
