Sky Explorer — Interactive Star Map & Night Sky Viewer
Look up with a little more curiosity.
Sky Explorer is an interactive night-sky viewer for exploring stars, constellations, the Milky Way and selected deep-sky objects. Set a location and time, look around the sky and zoom toward the Moon or a planet. Shared views help you show someone the same starting point for a discovery.
Open Sky Explorer ↗Free to start in your browser. The interactive tool uses JavaScript.

Try a small experiment.
- Check the observing location and date before interpreting what is above the horizon.
- Start with a wide sky view, then select a visible constellation, the Milky Way or a suggested object.
- Zoom toward the Moon or a planet. Read the labels and imagery source information as the type of view changes.
A couple of useful questions.
Why does my location change the sky?
Your latitude and longitude affect which directions are above your horizon and how the sky is oriented at a given time. A view prepared for another location may show objects you cannot see from yours.
Is a detailed object view what I would see with my eyes?
A map, a catalog marker and survey imagery serve different purposes. A detailed image may reveal structure far beyond naked-eye visibility. Use the view’s labels and sources to understand which representation is being shown.
Know what the tool represents.
Check the tool’s location, time and source notes. Catalog data, imagery and simplified rendering are aids to exploration; actual visibility also depends on weather, sky brightness, equipment and observing conditions.
