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. Astronomical Doodles
Google doodles are little drawings and animations that incorporate the Google name into a presentation of a person or event of note. Here are five doodles with an astronomy theme, including asteroids, a lunar eclipse and how the speed of light was calculated by observing Jupiter and Io.

2. European Astrofest 2017
It was the 25th Astrofest and how things have changed since the first one! No one knew then if other stars had planets. Pluto was still a planet and its discoverer Clyde Tombaugh was still alive. The Rosetta mission was in the very early planning stages, and Cassini-Huygens hadn't been launched.

3. Space Missions - Quiz
Space missions have taken us to the Sun and the Moon, asteroids and comets, planets, dwarf planets and moons, and looked beyond the Solar System. There have been so many missions it's hard to keep them straight. Can you match these descriptions with the missions?

4. Lunar Eclipses
Imagine the horror: Something is eating the Moon, leaving its face covered in blood. This was how people once viewed lunar eclipses. Find out what actually causes a lunar eclipse, why the Moon may turn red during an eclipse, and where a lunar eclipse becomes a solar eclipse.

5. Cosmonauts - Birth of the Space Age
The starter's pistol for the space race was fired on October 4, 1957. It was in the form of a small highly-polished sphere that orbited the Earth every 98 minutes. This was the Soviet Union's Sputnik, Earth's first artificial satellite. It shook up the United States, and there was more to come.

6. Cosmic Valentines
Valentine's Day is no assurance that love is in the air. Hearts and flowers aren't guaranteed to come your way. You may or may not get one of the billion valentine cards that are sent each year. But heart shapes are everywhere and anyone can admire them. Here is a cosmic selection for everyone.

7. Gravitational Waves What Are They?
In February 2016 news of gravitational waves went round the world. But what are these waves sometimes described as ripples in spacetime? To find out let's go back over a century to a time when Albert Einstein was completing the work that would change our view of the Universe.

8. Do Red Dwarfs Live Forever
Looking up at a clear, dark sky, you can see thousands of stars. Yet without binoculars or a telescope, the most common type of star is invisible. These are the small, cool red dwarfs that fill the sky and live practically forever.

9. Rosetta the Comet Chaser
Rosetta, the European Space Agency (ESA) spacecraft, traveled for ten years and billions of miles in order to rendezvous with a comet, accompany it as it moved through the inner Solar System past the Sun, and deploy a lander.

10. Kuiper Belt
Pluto was once the last outpost of the Solar System. Now we realize that it's the gateway to the Kuiper Belt, a disk made up of rubble left over from the formation of the Solar System. The Kuiper Belt is big and it's cold and the Sun would just look like a bright star from there.
