Naming the Extrasolar Planets
Naming the extrasolar planets W. Lyra Max Planck Institute for Astronomy, K¨onigstuhl 17, 69177, Heidelberg, Germany [email protected] Abstract and OGLE-TR-182 b, which does not help educators convey the message that these planets are quite similar to Jupiter. Extrasolar planets are not named and are referred to only In stark contrast, the sentence“planet Apollo is a gas giant by their assigned scientific designation. The reason given like Jupiter” is heavily - yet invisibly - coated with Coper- by the IAU to not name the planets is that it is consid- nicanism. ered impractical as planets are expected to be common.

The Night Sky December
The Night Sky December Equipment you will need Because of the darkness of our forest locations, you can see many wonders of the night skies with your naked eye, although your eyes will Boötes need a good 20 minutes to adjust to the darkness. Any bright lights, such as that from your torch, will set them back again. You can reduce this effect by putting a red filter on your torch. Equipment worth investing in includes: Lynx • Binoculars – cheaper and easier to carry than a telescope. Look for ones with glass lenses. • Camera – to capture that fantastic star scene forever • Tripod – essential for use with your camera • Telescope – worth investing in for the really committed stargazer • Google Skymaps – a superb free app, available for Android and Delphinius iPhone. You point your phone towards the sky and it shows you the constellations and identifies the stars using inbuilt GPS Lepus Getting started – your first 5 constellations to spot • Ursa Major (the Big Dipper) has been used by sailors since ancient times to locate the fixed-point Pole Star and navigate home • Leo (the lion) is it a lion, as the Greeks decided? Or is it K9 from Doctor Who? • Cassiopeia (the queen of Aethiopia) is one of the easiest constellations to locate and looks like a huge W, almost directly overhead • Cepheus (the king of Aethiopia) is one of 48 constellations Eridanus identified by 2nd century astronomer Ptolemy. Imagine a child’s drawing of a house, complete with roof • Orion (the hunter), with belt and sword, is perhaps the most famous constellation – and one of the few that actually bears some slight resemblance to its namesake Stargazing facts for kids • You can see the International Space Station without using binoculars, and you can track it moving across the sky • The sun is 300,000 times bigger than earth and 93 million miles Boötes Lynx Delphinus Lepus Eridanus away. -

Shepard 1 GUIDE TO THE STAR DECK Introduction As an introduction to astronomy, you cannot go wrong by first learning the night sky. You only need a dark night, your eyes, and a good guide. This set of cards is not designed to replace an atlas, but to engage your interest and teach you the patterns, myths, and relationships between constellations. They may be used as “field cards” that you take outside with you, or they may be played in a variety of card games. The cultural and historical story behind the constellations is a subject all its own, and there are numerous books on the subject for the curious. These cards show 52 of the modern 88 constellations as designated by the International Astronomical Union. Many of them have remained unchanged since antiquity, while others have been added in the past century or so. The majority of these constellations are Greek or Roman in origin and often have one or more myths associated with them. -

Centaurus was one of the 48 - - - constellations described in the 2nd century TE AHUA O TE RAKI I TENEI PO by astronomer Ptolemy, and it remains one Omega Centauri of the 88 modern constellations. Originally thought to be a single star, in 1677, this fuzzy spot was identified to High in the southeast, you will find two be a cluster that actually contains around bright stars that appear close together, 10 million individual stars. Pictured on called Alpha Centauri and Beta Centauri. the cover, Omega Centauri is a globular These stars mark the two front legs of the cluster: a collection of stars that orbits a centaur, and also act as the pointer stars galactic core. This is the largest of these in to help find the Southern Cross. the Milky Way, with light taking 150 years to travel from one edge to the other. Omega Centauri has a mass four million times that of our Sun, making it also the Image: Johannes Hevelius – Wikimedia Commons most massive cluster in our galaxy. The light coming from the millions of stars in the cluster has travelled for 15 800 years to reach us here on Earth. As this cluster is most easily seen from April to September, now is the time to start looking for it. Brighter than any other star cluster, Omega Centauri can currently be found high in the southeastern sky, along the back of the constellation Centaurus. -
