☃️ It's time to choose the 2026 Carnegie Science holiday card!

We've narrowed dozens of entries down to three spectacular science images. Now, we need your vote to choose the winner!

Polls are open from now through October 6. View the finalists & vote👇

"Dark Matter: The Greatest Holiday Light Is Not Always the One We See" Description: This illustration represents an artistic depiction of dark matter as the invisible force that quietly shapes and holds the universe together, influencing galaxies, clusters, and the vast structure of the cosmos through its gravitational pull. In much the same way, according to the artist, the spirit of the holiday season is an unseen force that draws humanity together."Little Lights in the Night" This image shows immunofluorescence imaging of Xenia soft coral cells. Cell nuclei are shown in blue, actin filaments in red, microtubules in green, and symbiotic algae in gray through autofluorescence.
Floating in Ocean's (Winter) Wonderland A close-up photograph of a seahorse anchored by its prehensile tail to the stalk of aquatic vegetation, showcasing its natural camouflage and delicate morphology.
