# How to Look Up Astronomical Events with Claude

Claude brings multi-step analytical reasoning to space exploration data, connecting NASA imagery with mission context and explaining the science behind astronomical phenomena at whatever knowledge level you need. Each query becomes a layered investigation where Claude traces relationships between current observations and broader research themes, identifies noteworthy near-Earth objects, and synthesizes data from multiple sources into a coherent picture of what is happening in our corner of the universe.

## Setup

claude mcp add toolrouter -- npx -y toolrouter-mcp

## Steps

1. Connect ToolRouter: claude mcp add toolrouter -- npx -y toolrouter-mcp
2. Ask Claude: "Get NASA imagery from the recent solar eclipse using space-data"
3. Claude returns the image with scientific context
4. Ask: "When is the next major eclipse visible from North America?"
5. Get detailed event information and viewing tips

## Example Prompt

```
Find NASA's Astronomy Picture of the Day from the last lunar eclipse. Explain what causes lunar eclipses and when the next one occurs.
```

## Tips

- Search specific dates around known astronomical events for the best coverage
- Ask Claude to compile a calendar of upcoming celestial events
- Combine with ISS tracking to plan a viewing session that includes the station flyover
