1. Serpens – a Tour of the Celestial Snake
Snakes were revered in ancient Greece. They represented wisdom, healing and rebirth. The constellation Serpens was included in a star catalog in the 2nd century, but it's much older than that. Seen through telescopes, it's rich in deep sky objects. Here's a tour of some of the highlights.

2. Serpens and Ophiuchus - Ancient Tales
What is the link between two ancient constellations and modern medicine? According to one myth, how did Ophiuchus end up in the sky? Why would a healer be associated with a snake?

3. What Is a Nebula
Nebulae are titanic clouds of gas and dust – celestial gossamer in the spaces between the stars. They're stellar nurseries, stellar graveyards and dark constellations. Some of their mysteries have been penetrated by infrared telescopes, but the cloaking dust still keeps some secrets.

4. Triton – Neptune's Captured Moon
The Solar System's large moons tend towards the weird and wonderful, and Triton is no exception. It has ice volcanoes, a strange “cantaloupe terrain”, and crazy seasons. It's the only large moon to orbit in the wrong direction, so it didn't form near Neptune. But where did it come from?

5. Haumea – Facts for Kids
Out in the Kuiper Belt, beyond Neptune and even farther away than Pluto, lie products of an ancient collision – they include a dwarf planet and its two moons.

7. Mercury - 10 Facts for Kids
Mercury is close enough to the Sun for lead to melt during the day. Yet there is ice at the poles. Before we had space probes, Mercury was a mystery hidden in the Sun's glare, but all that's changed.

8. Pluto - Names and Places
New Horizons was nearing Pluto in 2015 and the mission team would need names for the surface features they discovered. So they appealed to the public. The names would be informal ones, but they hoped the International Astronomical Union (IAU) would make them official.

9. Ophiuchus – the Tour
Ophiuchus the Snake Bearer represents the healer Asclepius who was a god of healing in classical times. He was associated with snakes – symbols of wisdom and regeneration – and in the sky he's entwined with Serpens. Here's a selection of some of points of interest in his constellation.

10. Luna - Earth's Daughter
The Moon has always been our celestial companion, lighting the night, its changes serving as a calendar. What is it, where did it come from, why do we only see one side of it, what is our future together?
