Incredible images show a huge iceberg drifting dangerously close to the shore in Greenland this week. The towering structure has been edging closer to a harbour in Innaarsuit, where local authorities have issued warnings to the public. It is now near the Royal Greenland fish factory and the local food store, where people are being advised to take care when visiting.

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. Taken with a Takahashi Teegul 60 telescope, Coronado SolarMax 60 double stacked, Vixen polaris mount, Player One Astronomy Neptune-M camera, 500 mm f/8.3, 0.3-millisecond exposure Location: Xiamen, Fujian, China, 24 January 2025
