Search for Earth's Twin – book review
Years ago, if you weren't serious about being an astronomer, a good career-killer would have been hunting for exoplanets. It's different now. Stuart Clark tells the story from the first discovery of a planet orbiting another star to the current Search for Earth's Twin.

Mimas – Death Moon of Saturn
Mimas is named for a giant in Greek mythology, but Saturn's moon is no giant. It's less than 400 km (245 mi) across and the smallest body we know of that's rounded by gravity. The moon also has a bizarre resemblance to the Death Star in George Lukas's Star Wars films.

Sun and Moon and the Calendar
If you look at your calendar to find today's date, you can see the month, days of the week and maybe some appointments. But you're also looking at something that tracks Earth's journey around the Sun, reflects three thousand years of history and helps to hold our society together.

Dorado and Volans – Facts for Kids
Flying fish live in warm oceans, and so do the mahi mahi fish. Sailors in the southern seas saw the flying fish using their side fins like wings to glide through the air – sometimes chased by hungry mahi mahi. Dorado (Mahi mahi) pursues Volans (Flying fish) in the stars of the southern sky.

Moon Phases and Eclipses – Help for Teachers
Moon phases and eclipses are easily seen, but rather abstract to understand. The first section of this article lists the basic concepts with some links to diagrams. The sections that follow suggest resources for teachers, both lesson plans and short videos available online.

Science Fairs – Astronomy and Space Project Ideas
Interested in astronomy or space-related science projects? Forget the model of the Solar System – that's for young children. Here are a number of ideas from several sources which should be a help to students and educators.

Science Fairs – Help for Teachers
Not everyone wants to plan a science fair, but science teachers still need to teach science. Projects are part of learning – not only learning science, but also learning transferable skills. The resources cited in this article aren't just for the fair, they could help you in the classroom too.

Vulpecula - the Little Fox
Vulpecula isn't a well known constellation, and its stars are dim. Yet it's interesting. It contains both the first planetary nebula and the first pulsar ever discovered, a handful of exoplanets, and part of the biggest structure in the known Universe.

Searching for Exoplanets
A number of planets orbiting stars outside the Solar System have been directly imaged, but most of the 4000 known exoplanets haven't been. Very few have been discovered by direct imaging. How do astronomers find what they can't see?
