Practical examples of creating a star chart for a specific time and location

Real-life examples of creating a star chart for a specific time and location

Let’s skip the abstract talk and jump straight into real examples of creating a star chart for a specific time and location. Seeing how other students (or you-in-the-near-future) could set these up makes the whole process feel a lot less mysterious.

Think of each example as a mini story: where you are on Earth, what time it is, and what you want to highlight in the sky. You can borrow any of these setups directly for your own science fair project, or mix and match ideas.

Example of a summer backyard star chart: Phoenix, Arizona, July 15, 9:00 p.m.

Imagine you’re standing in a warm Phoenix backyard on July 15 at 9:00 p.m. local time. You want a star chart that shows exactly what you’ll see if you look up.

Here’s how you’d build this example of creating a star chart for a specific time and location:

You open a planetarium app or website (like Stellarium Web or Sky & Telescope’s Interactive Sky Chart). You enter:

• Location: Phoenix, Arizona, USA (about 33.4° N, 112.1° W)
• Date: July 15, 2025
• Time: 9:00 p.m.

You set the chart to show the whole sky, oriented for an observer facing south. Your chart will likely highlight:

• The bright star Vega high overhead
• The Summer Triangle (Vega, Deneb, Altair)
• The bright star Antares in the constellation Scorpius low in the south

You print the chart or redraw it by hand on poster board, labeling the constellations and cardinal directions (N, S, E, W). On your display, you explain why some stars are higher in the sky in summer and how Phoenix’s latitude affects which constellations are visible.

This is one of the best examples of a simple, clean, and very understandable star chart setup for beginners.

Example of a winter evening star chart: London, UK, January 5, 8:00 p.m.

Now let’s jump across the Atlantic. Another example of creating a star chart for a specific time and location could be a cold winter evening in London.

You set up your chart like this:

• Location: London, UK (about 51.5° N, 0.1° W)
• Date: January 5, 2025
• Time: 8:00 p.m.

This time, when you generate your chart, different constellations dominate the sky:

• Orion rising in the southeast
• Taurus with the bright star Aldebaran
• The bright stars Sirius (in Canis Major) and Procyon (in Canis Minor)

Your science fair board could compare this chart to the Phoenix summer chart. These examples of creating a star chart for a specific time and location show how changing latitude and season completely reshapes the sky.

You might add a short explanation of Earth’s tilt and orbit, using simple diagrams and references to educational sites like NASA’s Night Sky resources or the NASA STEM Engagement pages.

Example of a star chart for a meteor shower: Perseids from Denver, August 12, 11:30 p.m.

Meteor showers are popular science fair topics, and they make fantastic real examples of creating a star chart for a specific time and location.

Let’s say you want to observe the Perseid meteor shower, which usually peaks around August 11–13 each year. You choose:

• Location: Denver, Colorado, USA (about 39.7° N, 105.0° W)
• Date: August 12, 2025
• Time: 11:30 p.m.

You generate a chart focused on the northeastern sky, because that’s where the radiant of the Perseids (in the constellation Perseus) appears. Your chart will show:

• The constellation Perseus above the horizon
• Nearby constellations like Cassiopeia and Andromeda

On your board, you explain that meteors in a shower seem to come from a single point, called the radiant. Your chart labels this point clearly.

This is one of the best examples of turning a star chart into a real observing plan: you’re not just mapping the sky, you’re using the chart to decide where and when to look.

For current meteor shower dates and tips, you can reference the American Meteor Society, which regularly updates shower predictions.

Example of a star chart for a lunar eclipse: New York City, March 14, 2025, 10:00 p.m.

Lunar eclipses are easy to observe and great for school projects. Another example of creating a star chart for a specific time and location is to map the sky during a partial or total lunar eclipse.

Suppose a visible eclipse is predicted for New York City. You choose:

• Location: New York City, New York, USA (about 40.7° N, 74.0° W)
• Date: March 14, 2025 (hypothetical example — always check real dates)
• Time: 10:00 p.m., during mid-eclipse

You generate a chart centered on the southern sky, where the Moon will be during the event. Your chart will show:

• The Moon’s position among the stars
• Nearby bright stars and constellations, maybe Leo or Virgo, depending on the real date

In your science fair explanation, you show how the Moon’s path across the sky follows the ecliptic (the apparent path of the Sun). You can point classmates to reliable eclipse predictions from sources like NASA’s eclipse pages.

This is a powerful example of creating a star chart for a specific time and location because it connects your chart to a specific, dramatic event in the sky.

Example of comparing two years: Same place, same time, 2024 vs. 2025

Here’s a clever project idea that uses examples of creating a star chart for a specific time and location to explore how the sky changes over years.

Pick one location and time, such as:

• Location: Chicago, Illinois, USA (about 41.9° N, 87.6° W)
• Time: 9:00 p.m.
• Date 1: September 1, 2024
• Date 2: September 1, 2025

You generate two star charts with the exact same settings, just different years. When you compare them, you’ll notice:

• The constellations look almost the same
• The positions of the planets may change quite a bit

Your board can highlight how stars appear fixed over short time scales, while planets shift noticeably from year to year. These side-by-side charts are real examples of creating a star chart for a specific time and location that also teach about planetary motion.

You can support your explanation with beginner-friendly astronomy guides from sites like NOIRLab’s educational resources or university outreach pages such as Harvard’s Center for Astrophysics.

Classroom example: Students each create a personal birthday sky chart

Teachers love this one. In a middle school or high school classroom, each student creates a star chart for:

• Location: their hometown
• Date: their birthdate
• Time: a chosen hour, like 9:00 p.m.

These examples of creating a star chart for a specific time and location turn into a whole gallery of personalized sky maps. Students compare:

• Which constellations appeared on different birthdays
• How location affects what’s visible (for students who were born in different cities or countries)

For a science fair, you could adapt this idea by focusing on several family members’ birthdays in different places. That gives you multiple real examples on one board, all connected by a fun theme.

Example of a Southern Hemisphere star chart: Sydney, Australia, June 21, 9:00 p.m.

Many star chart guides accidentally ignore the Southern Hemisphere, but including it gives your project a nice global touch.

Set up this example of creating a star chart for a specific time and location:

• Location: Sydney, Australia (about 33.9° S, 151.2° E)
• Date: June 21, 2025 (around the winter solstice in the Southern Hemisphere)
• Time: 9:00 p.m.

When you generate the chart, you’ll see:

• The Southern Cross (Crux) in the southern sky
• Bright stars like Alpha Centauri

On your board, you can compare this chart with one from a Northern Hemisphere city at the same date and time. These examples of creating a star chart for a specific time and location show that people in different hemispheres live under very different star patterns.

How to build your own best examples of creating a star chart

Now that you’ve seen several examples of creating a star chart for a specific time and location, let’s talk about how to build your own in a way that looks polished and science-fair ready.

Think in three simple phases: choose, generate, and present.

1. Choose your theme and locations

First, decide on a theme that ties your charts together. Some of the best examples include:

• “Summer vs. winter skies at my home”
• “How the sky changes between 2024 and 2025”
• “Meteor shower maps: where to look and when”
• “Northern vs. Southern Hemisphere night skies”

Once you have a theme, pick 2–4 specific examples of creating a star chart for a specific time and location that fit your story. For instance, you might choose:

• Two dates (summer and winter) in your hometown
• One meteor shower night
• One chart from a city in the opposite hemisphere

2. Generate your star charts with free tools

There are several reliable planetarium tools that let you create accurate charts for any time and place. Popular options include:

• Stellarium Web Online Star Map (easy, free, runs in a browser)
• Sky & Telescope Interactive Sky Chart
• Mobile apps like SkySafari or Star Walk

The process is usually the same:

• Enter your location (by city or latitude/longitude)
• Set the date and time
• Choose your view (whole sky, facing south, etc.)
• Turn on constellation lines and labels if needed

Then you either print the chart or redraw it by hand. Hand-drawing takes longer, but it makes your project feel very personal and shows effort.

3. Present your charts like a story, not just a collection of maps

What makes the best examples of creating a star chart for a specific time and location stand out is the storytelling. Don’t just stick charts on a board and label them. For each chart, briefly answer:

• Where is the observer?
• When are they looking?
• What’s special about the sky at that moment?
• How does this chart compare to your other examples?

You can add:

• Short paragraphs under each chart
• Arrows pointing to important stars or constellations
• A simple timeline or map of Earth showing your different locations

If you want to be extra impressive, you can also include a section on how astronomers use star charts professionally, with references to organizations like NASA or NOIRLab.
