Skyline Moon — For Classrooms
For Classrooms
Put the live Moon on your classroom screen. Free, every day, around the clock.
Skyline™ MOON UPDATE runs a 24/7 live Moon tracker on YouTube. It shows the Moon’s phase, how much of it is lit (illumination %), its age in days and its distance from Earth, computed in real time from NASA JPL’s public DE421 ephemeris and shown over NASA imagery. For moonrise and moonset times in your own town, use our free Your Moon lookup. There is nothing to sign up for and nothing to buy.
Live 24/7Open on YouTube ↗
Good to know before class. This is a live tracker, not a telescope camera: every number and map is calculated live from NASA JPL data. The top-right corner always shows the Moon’s % lit and phase name; the full Moon panel (exact illumination, age and distance) comes around about every 10 minutes, between panels on the planets and a world map. The stream plays background music, so you may want to mute it. This page embeds the video player only; YouTube’s live chat appears on YouTube itself, so preview it there before showing it to students. Moon pictures match the Northern Hemisphere view.
Three ways to use it in class
Bell-ringer
Have the stream on as students arrive. First question of the day: “What phase is the Moon, and how much is lit?” Two minutes, every day.
Follow up: is it waxing or waning, and how can you tell?
Daily moon journal
Students draw the Moon each day for two weeks, from the stream or from the real sky at home, and record the % lit.
By week two they can describe the pattern, then explain it.
Phase-prediction game
On Monday, everyone predicts Friday’s phase and % lit. On Friday, check the stream.
Closest guess wins. Students quickly learn the cycle is about 29.5 days.

Performance expectations quoted from nextgenscience.org.
- 1-ESS1-1
- “Use observations of the sun, moon, and stars to describe patterns that can be predicted.”My Moon Journal: daily observations of the Moon’s changing shape, then a prediction.
- 5-ESS1-2
- “Represent data in graphical displays to reveal patterns of daily changes in length and direction of shadows, day and night, and the seasonal appearance of some stars in the night sky.”Moon Phase Detective practices the same skill, graphing daily sky data to find a pattern. Moon phases themselves are not part of this performance expectation; they are formally modeled in middle school (MS-ESS1-1).
- MS-ESS1-1
- “Develop and use a model of the Earth-sun-moon system to describe the cyclic patterns of lunar phases, eclipses of the sun and moon, and seasons.”Why the Moon Has Phases: students use a Sun–Earth–Moon model and live illumination data to explain the cycle of lunar phases.
