This incredible image was captured over the Pacific Ocean by NASA astronaut Don Pettit, a renowned astrophotographer, while on an International Space Station mission. The trails on the left are made by stars that whizzed by during the long-exposure shot, joined by a fleet of flashing Starlink satellites. On the right is Earth’s glowing atmosphere and the yellow strip created by the soon-to-rise sun.

![Encounter Within One Second ? Zhang Yanguang This image captures the International Space Station (ISS) transiting across the solar disc. The solar background was captured separately with double-stacked etalon[an optical filter that isolates specific wavelengths, used to observe solar details], and reveals high-contrast chromospheric details. The imaging sequences were strategically combined during post-processing to preserve both the spacecraft?s crisp silhouette and the Sun?s intricate surface features.
