An astronomical research team is planning a series of space-related events, including setting up an observatory, observing a solar eclipse, tracking a comet, and showcasing a planetarium event. The challenge is to visualize these events on a timeline while considering their dependencies and durations.
Each event has:
- A defined **duration** in days.
- A **dependency** on another task, meaning it cannot start before its prerequisite is completed.
- A planned **start and finish date** based on the current date.
The goal is to create a **Gantt chart** that visually represents these events, showing their scheduling and dependencies in an intuitive manner.

### **Solution Explanation**
1. **Define Events and Dependencies**
- Events like "Solar Eclipse" and "Mars Rover Landing" depend on "Observatory Setup."
- Their durations vary (e.g., a Solar Eclipse lasts 1 day, while a Planetarium Show lasts 3 days).
2. **Set Start and End Dates**
- The **current date** is used as the reference starting point.
- The **start date** for an event is determined based on its dependency (if any).
- The **end date** is calculated as:
> End Date = Start Date + Duration (in days)
3. **Create a Gantt Chart**
- The timeline is plotted with events as horizontal bars.
- The x-axis represents time, and the y-axis lists the events.
- Dependencies are reflected in the order of event placement.
4. **Visual Insights**
- The chart allows the team to see which events overlap.
- It helps in **resource planning** by ensuring no conflicts occur.
- Adjustments can be made if needed to avoid scheduling issues.
By using this approach, the team can efficiently manage the execution of space-related events while keeping track of dependencies.
