Tonight Is the Darkest Night of the Month — and That’s Great News for Stargazers!
Quick Summary
Tonight, September 11, is a New Moon. That means the Moon is completely hidden from view, leaving the sky as dark as it gets all month. It is one of the very best nights of the year to go outside, look up, and be amazed by the stars.
What Happened?
The Moon goes through a cycle every 29 and a half days — from a big glowing Full Moon to a completely invisible New Moon and back again. Right now, we are at the New Moon phase. The Moon reached that exact moment today at 3:27 in the morning, Greenwich Mean Time.
During a New Moon, our satellite is between the Earth and the Sun. The side facing us gets no sunlight at all. The Moon becomes invisible — like a light switch turning off in the night sky.
And when the Moon’s light is gone, stars that are usually washed out come blazing back. It is the difference between trying to read a book with a flashlight shining in your eyes versus reading in a calm, quiet room.
Here is what you might be able to see tonight if you can get away from city lights:
The Milky Way — Our home galaxy stretches across the sky like a faint, hazy river of light. This month is actually one of the very last chances to see the Milky Way’s bright centre from the Northern Hemisphere before it tilts away for the winter. After November, it will not be visible again until spring.
Galaxies and Nebulae — The Andromeda Galaxy, the closest big galaxy to our own, looks like a tiny fuzzy smudge with the naked eye. Under tonight’s dark sky, it is much easier to spot.
Star Clusters — Groups of hundreds or thousands of stars bunched together, like sparkling confetti frozen in space.
Planets — Several planets are visible in September skies. Keep an eye out for bright Venus low in the west after sunset, and watch for Jupiter rising later in the evening.
The best way to stargaze is to find a spot far from town lights, lie on your back on a blanket, and give your eyes about 20 to 30 minutes to adjust to the darkness. Your eyes actually have a superpower — they gradually open up their pupils to let in much more light, making faint stars appear.
Why Does It Matter?
Night sky events like this cost nothing to enjoy. They connect us to the same stars that ancient people looked at thousands of years ago. And for many kids, one look at the Milky Way on a dark night is all it takes to fall in love with science and space.
Astronomers and space agencies like NASA encourage everyone to get outside during dark-sky windows. The darker the sky, the more you see — and the more questions you start to ask.
Big Words
- New Moon — the phase of the Moon when it sits between Earth and the Sun, making its face completely dark and invisible from Earth.
- Milky Way — the name of our galaxy; from Earth, it looks like a glowing, hazy band of light stretched across the night sky.
- Galaxy — a huge collection of stars, gas, and dust held together by gravity; the Milky Way contains over 200 billion stars.
- Nebula — a giant cloud of gas and dust in space, often glowing in spectacular colours; many are places where new stars are being born.
- Pupil — the dark circular opening in the centre of your eye that lets light in; it gets bigger in darkness to help you see more.
Fun Fact
The Andromeda Galaxy is so far away that the light reaching your eyes tonight left that galaxy about 2.5 million years ago — long before humans even existed on Earth!
Think About It
If you could travel instantly to any star or galaxy in the night sky tonight, which one would you pick — and why?
