Focus: The Gaia mission As Gaia - a new European Space Agency mission designed to measure the positions and motions of a billion stars - nears its launch date in November, Keith Cooper looks back at the achievements of its predecessor, Hipparcos, and the controversy over the distance to the Seven Sisters of the Pleiades. The European Space Agency's Gaia mission, launching later this year, will be the most sensitive astrometry mission ever, mapping the positions, motions and compositions of a billion stars, writes Stephen Clark. The Gaia spacecraft is going to investigate the histories of over a billion objects, from stars to quasars, writes Amanda Doyle. Features For imagers and non-imagers alike, Professor Greg Parker shows how you can produce your own beautiful deep sky mosaics using data captured by the professionals.

A nova peaking at magnitude four, Mark Armstrong and Keith Cooper set about describing what caused it to appear. Regulars It is all go in the Solar System writes Peter Grego as Comet ISON moves closer, Mars and Jupiter show improvement and Uranus reaches its best. The most distant object readily visible to the unaided eye is Messier 31, the enormous Andromeda Galaxy that presents a great target whether looking through the telescope, sketching or imaging. Ninian Boyle completes his examination of high-tech astronomy with a look at wireless telescope control. Atik's flagship CCD, the 11000, drinks up large swathes of sky on its giant Kodak chip, writes Olly Penrice. Skylight Telescopes of London, maker of bespoke classic refractors, have teamed up with TeleVue Optics of New York for their latest four-inch telescope, the AR101-15. Steve Ringwood was lucky enough to try one out. BUY ONLINE Free First Class delivery in the UK! DOWNLOAD The iPad and iPhone edition |
