Geminid meteor shower 2026: the best shower of the year, with almost no Moon
The 2026 Geminids peak on December 13 to 14 under a thin crescent Moon that sets early, which makes this one of the best Geminid years in a while. When to look from your city, where the radiant is hour by hour, how many you might really see, and why these meteors come from an asteroid, worked out with the same sky model as Everdust's Tonight's Sky.

Double pendulums and chaos: why a hair's difference changes everything
A double pendulum is chaotic, so two swings started a hair apart soon have nothing in common, even though the physics is exactly the same. Here is why, what a Lyapunov exponent measures, why weather forecasts run out at about two weeks, and how to watch it happen.

How galaxy simulations work, explained with what you see
A galaxy simulation turns stars into particles, adds up the gravity on each one and steps time forward, with shortcuts that decide what you see. Tidal tails come from differences in gravity across a galaxy; real galaxies merge because dark matter drains their orbits; and gas and new stars are always approximated. Explained with frames from a live simulation, by the maker of one.

When will the Milky Way collide with Andromeda? What Hubble and Gaia say
Andromeda is 2.5 million light-years away and closing at about 110 kilometers a second. A 2012 Hubble study forecast a head-on collision in about 4 billion years; a 2025 re-analysis with Gaia data puts a merger within 10 billion years at roughly a coin toss. Here is what changed, and what a collision would do.
What a spinning black hole really looks like
A spinning black hole looks like a dark shadow ringed by a thin bright photon ring, with its glowing disk bent up over the top and under the bottom, one side far brighter than the other.

A free live space screensaver for Mac, and what to run on Apple TV
Everdust Screen Saver is a free Mac screen saver where galaxies collide, a black hole spins and starlings flock, all simulated live. Apple TV doesn't take third-party screen savers, so there Everdust's Ambient mode does the same job.
How a star is born
A star is born when a cold cloud of gas collapses under its own gravity, spins up into a disk and heats its center until hydrogen fuses. Here is how it happened to the Sun, step by step, with a live simulation you can watch.
What is a strange attractor?
A strange attractor is the shape a chaotic system settles onto, a path that never repeats and never escapes. The Lorenz butterfly is the famous one; here's what makes it strange, and a free visualizer to watch four of them live.
What is Everdust?
The short version, with the facts in one place: what Everdust is, what's in it, where it runs and what's free.
Why stars almost never collide when galaxies do
When two galaxies collide, almost none of their stars hit each other, because the gaps between stars are enormous. Gravity does the damage instead, and you can watch it happen in a free galaxy collision simulator.
