A grayscale image captured by the STEREO A spacecraft showcasing Comet McNaught. The comet's bright coma creates a horizontal stripe, while its dust tail stretches across a vast area (30 million kilometers). A fainter, neutral iron tail, a first-ever detection, is also visible. Bright Venus appears in the upper left corner.

A stunning grayscale image of Comet McNaught captured by the STEREO A spacecraft. The comet's bright coma dominates the lower portion, while its extensive dust tail stretches across a vast expanse (30 million km). A fainter, neutral iron tail, a rare discovery, is also visible. Bright Venus appears near the top left, causing a slight image artifact.

A stunning long-exposure photograph captures Comet NEOWISE (C/2020 F3) streaking across the night sky above Suchy Vrch, Czech Republic. The comet's bright coma and two distinct tails – a yellowish dust tail and a fainter bluish ion tail – are clearly visible against a backdrop of stars and a tranquil landscape. The image showcases the intricate details of the comet's tail, extending over 20 degrees from its head.
