A mysterious and breathtaking red glow recently appeared over the Atlantic Ocean, capturing the attention of pilots, scientists, and the public worldwide. High above the clouds, aircraft crews witnessed an enormous red illumination stretching across the horizon — a scene so strange it seemed straight out of a science fiction film.

Photos of the glowing sky quickly went viral, sparking countless theories ranging from UFO activity to natural atmospheric anomalies. But while the images looked otherworldly, experts say the cause is likely rooted in something far more familiar — deep-sea fishing vessels.
