Moon Phases
New moon nights are best for faint stars. Full moon nights wash out dim objects but make the moon itself spectacular.
No telescope needed
A month-by-month pocket guide to the planets, constellations, moon phases, and bright events you can see with just your eyes. Pick your month, step outside, and look up.

New moon nights are best for faint stars. Full moon nights wash out dim objects but make the moon itself spectacular.
Meteor showers and eclipses appear here when scheduled. Most months have at least one minor shower.
Planets don’t twinkle like stars. They look like steady, bright points of light. Here’s what’s up this month.
Groups of stars that form recognizable patterns. Use the brightness key below to know which ones stand out.
The International Space Station looks like a bright, steady light gliding across the sky. No blinking lights. No sound. It takes about 5-6 minutes to cross from horizon to horizon.
This is a representative pass for illustration. Real-time pass data requires a location lookup, which this offline guide cannot provide. Check NASA’s Spot the Station for your exact location.
Everything you need to enjoy the night sky without any equipment.
Pick your month at the top of the page. The panels below update to show what’s visible. Each planet card tells you when to look (evening or morning), which direction to face, and how bright it will appear. Constellation cards include the brightest star in that group and a simple shape description you can trace with your eyes.
The moon phase strip shows when the moon is new, half, or full. Plan your stargazing around new moon nights for the darkest skies. Save full moon nights for moon watching itself. The moon is stunning through nothing more than your own eyes.
Planet vs. star: Stars twinkle. Planets usually don’t. If the bright light in the sky stays steady and doesn’t flicker, it’s probably a planet. Also, planets always appear along a band across the sky called the ecliptic. If the bright object is off that band, it’s almost certainly a star.
Satellite vs. airplane: Satellites look like slow-moving steady dots. They don’t blink and they don’t change direction. Airplanes have blinking lights and move with a slight curve. The ISS is the brightest satellite and moves faster than most others.
Shooting star: A quick streak of light that lasts less than a second. These are tiny bits of space dust burning up in the atmosphere. You might see one or two per hour on a normal night. During a meteor shower, you might see dozens.
Kids love spotting things, so give them a mission. Ask them to find the brightest object in the sky. Challenge them to count how many stars they can see in a small patch of sky. Trace a constellation shape with your finger and have them copy it. Bring a blanket, hot chocolate, and a red-light headlamp so you can read this guide without ruining your night vision.
A simple pair of binoculars (7x50 or 10x50) opens up craters on the moon, Jupiter’s four largest moons, and star clusters. You don’t need anything expensive. Even cheap binoculars reveal a surprising amount.

A red-light headlamp preserves your night vision while you read a sky chart or find your way across a field. White light resets your dark adaptation and takes 20 minutes to recover from. Red light keeps your eyes ready to see faint stars.
