Astrophotographers capture night sky full of satellites as comet passes Earth
Images from the Teide Observatory reveal over 1,600 satellite trails from roughly 400 satellites, highlighting growing interference with astronomical observations, researchers said.
- Astrophotographers captured long-exposure images showing artificial satellites crossing Comet C/2025 A6 using 135mm full-frame imaging equipment at Teide Observatory, Tenerife.
- According to the Nature study this month, Earth could be orbited by half a million artificial satellites if US Federal Communications Commission filings result in launches, with Starlink now accounting for more than half of the roughly 13,000 satellites in low-Earth-orbit constellations.
- Repeated exposures over a little more than half an hour recorded more than 1,600 visible trails, representing around 400 individual satellites, while Lemmon's ion tail stretched more than 13 degrees.
- The Instituto de Astrofísica de Canarias said it left a `not cleaned` composite image to raise awareness about near-space contamination, and researchers hope the visuals will prompt reflection on astronomy and the night sky's natural beauty.
- A composite `uncleaned` image and time-lapse video show interference that turns a pristine celestial view into a web of luminous traces, with observers describing the night sky being crowded by satellites.
