What scenes are there in space, at which locations, and with what characteristics?

What can you see in space?

You may have heard countless times that the Great Wall of China is the only man-made object visible from space. But that's not the case: The Great Wall is invisible to the naked eye from space, at least in low-Earth orbit. So, what landscapes can be seen from space? The American "Mother Nature" website has collected the top ten giant visible objects in space for us. Let's experience these unique landscapes together.

The Himalayas

With 14 peaks more than 26,000 feet high and more than 100 peaks over 20,000 feet high, the Himalayas are undoubtedly impressive. Looking down at these giant snow-capped peaks from space will leave you in awe. In fact, it is these white peaks that make the mountain stand out from space. Located between the Tibetan Plateau and the Indian subcontinent, the Himalayas are easily identifiable. According to NASA, this photo was taken with a handheld large-format camera aboard the Space Shuttle Challenger and records the great Himalayas from the southwest.

The Great Barrier Reef

Located in the shallow waters off the eastern coast of Australia, it is the largest living structure in the world (made entirely of coral). At 1,600 miles long and covering a total area of ??13,000 square miles, it's no wonder this geographically unique Great Barrier Reef can be identified in satellite photography. With endless coral jungles and more than 1,500 species of fish, the Great Barrier Reef deserves a close look and appreciate its huge underwater landscape. Satellite photos show it stretching out parallel across northeastern Australia.

Dubai Artificial Island

Composed of numerous man-made sand islands two miles away from the mainland of Dubai, the Arab Emirate, the World Island (on the right) and the Palm Island are built in the shape of a world map and a palm tree. Visible from space, the terrains are made using sand harvested from the shallow waters of the Persian Gulf. Dubai even plans to build a replica of the solar system including the sun, stars and planets, calling it a "universe island" artificial terrain.

Cities in Lights

Other than the shapes of continents, the most easily identifiable geographical features in space are cities in lights. Only major cities with enough wattage can be seen from orbiting satellites, and a few can even be seen with the naked eye. In the eastern half of the United States, Western Europe and India, countless lights, bright or dark, together form a huge lighting area.

The Pyramids of Giza

You cannot clearly see the Egyptian pyramids with the naked eye from space, but astronauts on satellites and space stations love to look at them from a distance. With a zoom lens or high-resolution camera, the pyramid's shape is clearly visible in the air. Its desert landscape is also evident, and satellite images show that the pyramid is now partially surrounded by the modern city of Cairo (and adjacent to a large golf course).

Almeria Greenhouse, Spain

Ever wonder what 64,000 acres of plastic greenhouse buildings would look like in space? Almeria, Spain, lets you know it all. This historic city in Andalusia, in the far southeast of Spain, is the center of Spain's agricultural industry, with nearly three-quarters of its crops exported to other parts of Europe. The reflections of these side-by-side greenhouses are easily visible in daylight from space.

Grand Canyon

The Grand Canyon is breathtaking in appearance, there is no doubt about it. However, viewing its panoramic view in one go requires access to Earth orbit. Satellite images of the Grand Canyon and pictures taken by astronauts aboard the International Space Station show not only its unique shape, but also the area's natural and man-made features, including Lake Mead, the Colorado Plateau, and even Las Vegas.

Ganges Delta

220 miles wide, including Bangladesh South and parts of West Bengal, India, it is one of the most geographically distinct regions in the world. It is rich in wildlife and has disastrous floods almost every year. The interesting geographical features of the Ganges Delta are the most beautiful when viewed from orbiting satellites. The river has a lot of sediment in the Bay of Bengal and seems to have a light milky white color. In this photo taken by MODIS on NASA's Terra satellite, the Ganges flows into the Gulf southeast of the image.

The Amazon River and its tributaries

The Amazon River cuts through nearby dense forests and is long enough that it can be seen from space. Its two main tributaries, the Rio Negro and the Rio Solim?es, flow into this large river near Manaus. Their combined water transport network can be seen from space, especially during floods. . The Amazon rainforest appears as a vast dark area in South America on satellite images.

Phytoplankton

It is an unusual terrestrial feature that can be seen at random locations in space. It is composed of countless tiny organisms (single cells) and can be seen on artificial satellites orbiting the earth. Feathered vortices often occur close to coastlines and cover large areas of the ocean. Phytoplankton thrive in high-temperature areas, and when they come into contact with the delta's nutrient-rich water, the eddies grow larger. Swirls of calcium-rich phytoplankton appear milky white, others appear red.

They are an important source of nutrition for marine animals, including whales, but certain species (called red tides) are toxic and can cause disease in animals and humans.
