Is it a bird? Is it a plane? No, it's the Hubble Space Telescope transiting the sun at around 17,000 mph (27,000 kph).

Astrophotographer Efrain Morales captured the dramatic footage on Dec. 15, 2025, from the city of Aguadilla in Puerto Rico. In the video, the Hubble Space Telescope appears as a tiny, defined silhouette gliding past the sunspot known as AR4308.
