Stellarium Web
Kids pull up tonight’s sky for any spot on Earth, switch on constellation art and fast-forward time to watch the stars wheel.
Stellarium Web is a planetarium inside a browser tab. It opens on the sky over your location at this moment, with stars, planets and the Moon in their real positions. Kids can turn on constellation lines and labels, then layer on the artwork so the hunter, the bears and the swan appear across the dark. A time control speeds the night along, rewinds to a birthday or leaps centuries ahead, and a location search hops to the far side of the planet for a sky they’ve never stood under. Tap a star or planet and its name, brightness and distance pop up. It looks especially handy as a warm-up before a backyard stargazing evening, and with so many controls on screen it may suit slightly older kids, or a grown-up sitting alongside.
