How far away they are is a question that has confounded scientists for centuries.

Over the last few hundred years, many scientific careers – and considerable resources – have been devoted to measuring their positions and motions with ever increasing accuracy. And in the last two decades of the 20th century, the European Space Agency developed and launched the Hipparcos satellite, around which this account revolves, to carry out these exacting measurements from space. What has prompted these remarkable developments? Why have governments been persuaded to fund them?

What are scientists learning from astronomy's equivalent of the Human Genome Project? This book traces the subject's history, explains why such enormous efforts are considered worthwhile, and interweaves these with a first-hand insight into the Hipparcos project, and how big science is conducted at an international level. The involvement of amateur astronomers, and the Hipparcos contributions to climate research, ‘death stars' passing close to the Sun, and the search for extra-solar planets and even intelligent life itself, are some of the surprising facets of this unusual space mission.

In this book the author has brought together the experience of small telescope users to provide an insightful look into just what is possible. It is written for newcomers to astronomy and experts. Topics covered include: refractors, reflectors, advanced catadioptric telescopes, and a simple radio telescope. Almost everyone with an interest in practical astronomy will want this book.

Author by: Robert W. Argyle Language: en Publisher by: Springer Science & Business Media Format Available: PDF, ePub, Mobi Total Read: 71 Total Download: 220 File Size: 47,8 Mb Description: There are more binary stars visible in the night sky than there are single stars, and there are enormous numbers of wide, faint pairs under-observed or not observed at all - professional astronomers just don't have the available time to study them. This is where amateur astronomers can help. Bob Argyle, a professional astronomer at Cambridge University, shows where enthusiastic amateur observers can best direct their efforts. The book caters for the use of every level of equipment, from simple commercial telescopes to micrometers and CCD cameras. Amateur astronomers who have gone beyond 'sight-seeing” and want to make a genuine scientific contribution will find this a fascinating and rewarding field - and this book provides all the background and practical information that's needed.

Includes a free CDROM represents an informative snapshot of continually evolving catalogues, including; the United States Naval Observatory catalogues, the WDS, the Second Delta-m catalogue, the Fourth Interferometric catalogue and the Sixth orbital catalogue to be used in conjunction with the USNO website. Author by: R. Argyle Language: en Publisher by: Springer Science & Business Media Format Available: PDF, ePub, Mobi Total Read: 37 Total Download: 805 File Size: 41,8 Mb Description: The second edition of Observing and Measuring Visual Double Stars (2004) is the definitive book for those who are serious about this fascinating aspect of astronomy. It deals with equipment (you can start modestly with commercial or even home-made instruments), observing methods using binoculars upwards to advanced instrumentation and techniques, including speckle interferometry. The astronomy of double stars, including orbital calculation, is given its own section. This second edition of this popular book contains a significant amount of completely new material, inspired by the work done by observers – particularly in the USA – since the first edition was published. This includes the use of the Internet to carry out astrometry (precise astronomical measurement) using existing survey plates and films.

The new edition contains an excellent guide to sketching double stars, a topic not previously covered. In addition, there is information about how to image double stars of unequal brightness, always a difficult matter but now somewhat easier because of advances in hardware and image-processing software. Nearly all of the chapters and tables have been updated. The CD-ROM that accompanied the first edition of Observing and Measuring Visual Double Stars is replaced by access to the Springer Extras web site.
