The night sky often hides surprises for patient stargazers. In Saudi Arabia’s al-Ula, one such moment came recently. A bright meteor flashed across an hour-long exposure.

What was the intended capture?
Astronomers were photographing the Pleiades star cluster (M45). Long exposures were made to show faint nebulosity clearly. These images reveal bright stars and surrounding blue-reflecting dust.

Unwanted objects often spoil frames during extended exposures. Stuck pixels, cosmic ray hits and bright clouds interfere. Sometimes the Moon, airplane trails or faint satellites appear. Even insect trails or lens flares can complicate results.

What made this image different?
This time, a meteor unexpectedly streaked across the frame. The fast rock fragment produced a striking green glow. Scientists suggest metals in the meteor vapourised on entry.

Alongside the meteor, famous bright blue stars appeared. Less-known stars and fainter blue light were also visible. Surrounding dust in the cluster reflected starlight, adding depth.
