Now You See It, Now You Don’t! The Moon Is Hiding Jupiter This Morning
Quick Summary
Early this morning, the Moon passed directly in front of Jupiter, making the giant planet vanish from the sky for about an hour. This rare event is called a lunar occultation. Skywatchers across North America had the chance to see it happen live.
What Happened?
Jupiter is the largest planet in our solar system. It is so big that more than 1,300 Earths could fit inside it. Yet even a planet that enormous can disappear — if the Moon happens to get in the way.
That is exactly what happened in the predawn sky on Tuesday, October 6. A thin crescent Moon slowly drifted in front of Jupiter and blocked it from view. Scientists call this a lunar occultation, which comes from a Latin word meaning “to conceal.”
For lucky skywatchers in the eastern and central United States and southern Canada, Jupiter simply blinked out — gone, as if someone had unplugged a bright lamp. About an hour later, the planet popped back out from behind the Moon’s dark edge. Cities like New York, Chicago, and Toronto had good views, and even binoculars would have shown Jupiter’s four big moons crowding close to the lunar edge just before the planet disappeared.
This event was visible in parts of the Caribbean and Africa too. For people in the western United States, the Moon rose with Jupiter already behind it, so they caught only Jupiter reappearing — still quite a sight.
Astronomers say this is one of the best Jupiter occultations visible from North America since 2004. That is over 20 years ago! It is part of a series of eight such events that will happen between September 2026 and May 2027, so this is the second of eight chances to watch Jupiter play peek-a-boo with the Moon.
Why Does It Matter?
Occultations like this one remind us that the sky is always in motion. The Moon never stops moving. Every month it sweeps across the sky and passes near planets and star clusters. Usually the Moon just slides by. But every so often, it lines up just right and covers something behind it — giving us a front-row seat to the clockwork of our solar system.
Events like this one can even help scientists measure the exact size of distant objects by timing exactly how long they stay hidden.
Big Words
- Occultation — when one object in space passes in front of another, hiding it from view
- Crescent Moon — the thin, curved sliver of Moon you see when only a small part is lit by the Sun
- Galilean moons — Jupiter’s four largest moons, first spotted by the scientist Galileo in 1610
- Conjunction — when two objects in the sky appear very close together as seen from Earth
Fun Fact
Jupiter is so bright in the night sky that, after the Moon and Venus, it is often the third-brightest object you can see — brighter than any star!
Think About It
If you were an astronaut orbiting Jupiter when the Moon passed in front of it, what do you think you would see from your spaceship?
