About Meteor Shower Screensaver

A deep night sky scattered with stars, threaded by a faint galactic band. Every second or two, a meteor streaks diagonally across the canvas with a glowing tail that fades from bright cream at the head to deep amber, then to nothing. Each meteor's exact angle and starting point varies, so the sky never feels patterned. The spawn rate is calibrated to feel like a real shower at peak: enough that you'll always see one if you wait a few seconds, sparse enough that they remain individual events.

What the Meteor Shower Screensaver Does

A 200-star night sky with a luminous galactic band stretching across the canvas. Every 1-2 seconds, a meteor streaks diagonally with a bright cream head and a tail that fades to deep amber. Each meteor's angle, starting point, speed, and tail length vary to simulate the natural diversity of real meteors. The spawn rate is calibrated to feel like a real shower at peak — frequent enough that you always see one if you wait, sparse enough that they remain individual events. Everything renders client-side on HTML5 Canvas at 60fps with no external assets.

Sleep Aid and Bedside Display

The meteor shower is an effective sleep-aid background on a bedside monitor or tablet. The slow drift of stars provides a calming visual anchor, while the occasional bright meteor streak adds just enough interest to quiet a racing mind without being stimulating enough to prevent sleep onset. Reduce your display brightness for overnight use — the dark sky and star field keep the room dim while the meteor tails provide gentle, predictable visual events. The animation runs indefinitely without interaction.

Astronomy Education and Planetarium Displays

Educators use the meteor shower as a live visual aid when explaining meteoroid streams, radiant points, or the relationship between comets and meteor showers. The animated streaks make abstract orbital mechanics tangible for students. Planetariums, science museums, and nature centers run it on lobby screens and exhibit panels to create an engaging astronomical atmosphere. The 200-star field provides the depth and scale of a real night sky, and the galactic band adds the diffuse glow visible from truly dark locations.

Pro Tip: Dim the Room for Best Effect

The meteor shower is designed for dark environments. Lower room lights and reduce display brightness — the stars become more vivid, the galactic band more prominent, and the meteor tails more dramatic against the dark sky. The effect is closest to real stargazing when the room is fully dark and the screen is the only light source.

How to use it

  1. 01

    Go fullscreen

    Press F and dim the room lights for the best effect.

  2. 02

    Wait and watch

    Meteors spawn every 1-2 seconds on average. Some come in clusters, then a quiet beat, then more.

  3. 03

    Track the tails

    Each meteor's tail is brightest at the head and fades over its length.

Frequently asked

The shortest path between you and the answer.

How often do meteors appear?

Randomized intervals simulate a real shower. Sometimes two or three appear close together, sometimes there is a lull.

Are the stars astronomically accurate?

Procedurally placed for visual authenticity rather than mapping to specific constellations.

Is this tool free?

Yes. Every ScreenTools.co tool is free, with no account, no paywall, and no install.

Does it work on mobile?

Yes. Layouts adapt to phone and tablet screens. Mobile Safari restricts true fullscreen, but the page fills the viewport and you can add the page to your Home Screen for an app-like experience.

Does it work offline?

Once a tool's page has loaded once, the runtime is local. A few tools that fetch fonts or icons need the first hit online; after that, refresh works offline.

Does this collect my data?

No personal data leaves your browser. The site has lightweight, privacy-respecting analytics for aggregate counts (which tool was opened) and nothing else.
