A stunning photo captured by an astronaut aboard the International Space Station (ISS) and released by NASA reveals a towering cumulus congestus cloud in the background of the Arabian Peninsula.
An image taken while the ISS was orbiting over South Asia is a beautiful example of cloud formation in action.
The photograph shows the western coast of the Persian Gulf with the countries of the United Arab Emirates, Saudi Arabia, Qatar and Bahrain visible in exquisite detail.
Notable landmarks such as Doha and Ras Laffan in Qatar and Al Hufūf and the lush oasis of Al Hasa in Saudi Arabia are discernible along the coast, their urban and natural textures creating a striking contrast to the natural cloud formation.

A cumulus congestus cloud rises dramatically in the image, casting a dark shadow on the landscape below.
Cumulus clouds come in a wide variety of shapes and sizes, often thought of as the classic fluffy white clouds that stream across the sky.
“When viewed from above, sunlit cumulus congestus is brighter than other types of cumulus,” the International Cloud Atlas says on its website.
“The upper parts, with well-defined and heavily shadowed ridges and domes, have the shape of large flowers, huge chimneys or towers. Their summits, which may reach very different levels, sometimes emerge from a layer of haze or from a fairly continuous layer of cloud.”
These clouds form when warm, moist air rises rapidly in unstable atmospheric conditions.
The visible presence of smaller cumulus clouds near its base indicates the early stages of potential cumulonimbus development, which could bring intense precipitation or thunderstorms.

This formation, which aligns with the coast, suggests that offshore winds played a key role in its formation. As air heated above the Earth’s surface flows inland, it rises and condenses, triggering the process of cloud formation.
On visual appeal, sunglint appears over the waters of the Persian Gulf in the lower right corner of the image. This optical phenomenon occurs when sunlight is reflected directly back to the viewer, revealing the shimmering patterns and surface textures of the Persian Gulf.
The horizon at the top of the image separates Earth’s atmosphere from the vast blackness of space, a reminder of the unique position of the ISS, which at this point was about 355 miles above Earth.
The photo was taken on September 19, 2024 and listed by NASA Earth Observatory as the December 21 Image.
It was taken by a member of Expedition 71 on the ISS.
The cropped and enhanced image is part of NASA’s effort to provide high-quality Earth observations.
