Briefings

This APOD image from October 25, 2026, displays a computer simulation of dark matter filaments in black against a background of baryonic matter in orange. The simulation highlights how dark matter pervades the universe, though recent research suggests dark energy may now dominate the universe's expansion. The image was created by Tom Abel and Ralf Kaehler for NASA's APOD archive.

Key points

• The image shows dark matter filaments in black and baryonic matter in orange within a simulated universe.
• Dark energy is now considered the dominant source of gravity in the universe, replacing dark matter's traditional role.

Context

This image is part of the American Museum of Natural History's Hayden Planetarium Space Show, Dark Universe, and serves as a visual representation of dark matter's pervasive influence on cosmic structure.

Limitations

The evidence is a computer simulation rather than direct astronomical observation. The specific date is 2026, and the simulation's statistical match to real observations is noted but not quantified.
