Here are the top ten articles for the Astronomy Site! These rankings are live and get reset at the beginning of each month, so check back often to see what your fellow visitors are most interested in!

1. Star-gazing – Seeing in Dim Light
How can you see an object by not looking at it? Why do aurorae and deep-sky objects tend to look grey? How can an eyepatch and a red flashlight be useful to an astronomer? Why can a camera flash ruin a night's observing? Answers to all these questions are related to the way our eyes react to light.

2. Red Dwarfs - Ten Facts for Kids
If you go outside on a clear dark night, you might see a few thousand stars. But without a telescope, not a single one will be the most common type of star in the Universe. You won't see red dwarfs, the stars that will still be shining in the far distant future when all the others have died.

3. Does Sound Travel through Space
Can sound travel in space? The short answer is no, but it's not so simple. The Sun produces sound waves we can't hear. And then there's a black hole that astronomers have detected endlessly singing a B-flat over tens of thousands of light years.

4. Triton – Captive Moon of Neptune
The Solar System's big moons are weird and wonderful, and Triton is no exception. It has ice volcanoes. Its "cantaloupe terrain" is unique in the Solar System. It's unlike the other large moons. And it orbits in the wrong direction, so it didn't form near Neptune. But where did it come from?

5. Nebulae - Ten Facts for Kids
Nebulae are great clouds of gas and dust in the spaces between the stars. Some of them are made from dying stars. Others are the nurseries for new stars. Here are ten facts about these surprising objects.

6. Kuiper Belt - Facts for Kids
Pluto's not the last planet, it's the first Kuiper Belt Object. The Kuiper Belt is made up of millions of icy bits left over from the beginning of the Solar System. It starts at 30 AU - that's 30 times farther from the Sun than the Earth. From there it stretches for another 2 billion miles!

7. Life and Death of the Sun
In the distant future the Sun will be many times its present size and thousands of times brighter. It will seed the Galaxy with elements like carbon and oxygen–perhaps for life on a world yet unborn. Then it will collapse into a tiny dead sphere. For a time, a beautiful nebula will mark its place.

8. Oort Cloud - Facts for Kids
Where do comets come from? The Oort Cloud is home to a trillion comets at the edge of the Solar System, nearly half way to the next star. Sometimes they get kicked out and sometimes they come to visit the inner Solar System.

9. Maria Mitchell
Maria Mitchell was a true pioneer woman. She didn't brave a physical wilderness. Hers was the harder job of pioneering higher education for women. She was the first American woman to discover a comet, the first to be elected to scientific societies and the first woman professor of astronomy.

10. Halley's Comet for Kids
It visits every 75 years or so, appearing like a celestial ghost in our skies. In the past it has been a bad omen and scary object, but last time it came it was a big event around the world. What is it? Halley's Comet, the most famous comet of all.
