Night Sky Tonight (Dec. 21, 2025): Winter Solstice Stargazing, Ursid Meteor Shower Peak, Jupiter’s Glow — and Interstellar Comet 3I/ATLAS
The December solstice occurs Sunday, bringing the longest night of the year for the Northern Hemisphere. A thin crescent Moon will keep skies dark for the peak of the Ursid meteor shower overnight. Jupiter remains prominent, while comet 3I/ATLAS lingers after its closest approach to Earth two nights earlier. Stonehenge drew thousands for solstice sunrise celebrations.
