Story summary

The Hubble Space Telescope was filmed transiting the sun on December 15, 2025, in Aguadilla, Puerto Rico, at about 17,000 mph.
The event lasted 1.01 seconds.
Astrophotographer Efrain Morales used a Lunt LS50THa solar scope and transit-prediction software to record the moment against sunspot AR4308.
