Most people who want to try stargazing have no idea where to start looking. Astronomy apps require you to already know what you're looking for, and generic sky guides don't account for your specific location, time zone, or the current season. The result is a lot of standing outside in the dark, looking up, and giving up.

The whats_visible skill returns a location-specific list of what is currently above the horizon — planets, bright stars, constellations, and notable deep-sky objects — with altitude, azimuth, and rising and setting times. Combined with moon_phase, you know whether the moonlight will wash out fainter objects before you even step outside.

Beginners looking for their first guided sky session, astronomy club members planning observation nights, and science teachers building outdoor classroom activities all use this to get the right starting point for a night of observation.

Claude turns raw sky data into a guided observing session — telling you which objects to start with for your equipment level, explaining what each object looks like and why it's interesting, and recommending the best hour of the evening to observe based on altitude and moonrise time. It makes a night of stargazing feel planned rather than aimless.

How to find out what's visible in the night sky tonight

Once connected (see setup above), use the Night Sky tool — the same steps work with Claude, ChatGPT, Microsoft Copilot, OpenClaw, and any MCP client:

  1. Ask: "What's visible in the night sky tonight from Edinburgh using night-sky?"
  2. Claude returns a list of visible planets, stars, and deep-sky objects with positions
  3. Also ask: "What is the moon phase tonight?"
  4. Request: "Which five objects should I start with using binoculars?"

Example prompt

Try this with the Night Sky tool
Tell me what's visible in the night sky tonight from Bristol. I have a pair of 10x50 binoculars. What should I look for, in what order, and where should I point?

Tips

  • Specify your equipment (naked eye, binoculars, telescope aperture) for tailored recommendations
  • Ask about the best observing window — high altitude objects are clearest, low ones are dimmed by atmosphere
  • Request a moon phase update to know if faint objects like galaxies will be visible or washed out
