light trails

A landscape photograph from Hellhole Canyon Trail in Anza-Borrego Desert State Park, California, shows a cholla cactus beneath clouds lit up at sunrise, with a faint rainbow visible amid light rain. The image is being shared by outdoor and photography enthusiasts, who are praising the rare combination of desert scenery, morning light and rain in the Southern California park.

A trail runner described an enjoyable outing that became difficult on the final stretch, when sunset brought out wildlife and the dog, Penny, kept darting after new smells, making a steady pace nearly impossible. It is a light personal anecdote shared with running and dog-running communities.

A photographer shared a long-exposure shot of morning street traffic in a small town, with car headlights rendered as streaking light trails. The image, captioned 'The Fast and the Blurrious', blends urban street photography with the playful pun on the film franchise, and is drawing appreciative attention from photography and autos fans.

NASA's Voyager 1, the most distant human-made object, is currently about 25.76 billion km (16.01 billion miles) from Earth and is expected to reach a distance of one light-day — the distance light travels in a full day — in roughly 48 days. Its twin, Voyager 2, trails behind at about 21.55 billion km (13.39 billion miles). Space enthusiasts are marking the milestone as the spacecraft continues its mission launched in 1977.
