The new Philip's 101 Objects To Spot In The Night Sky is a fun and practical guide to identifying and observing 101 of the most fascinating and exciting sights in the northern-hemisphere sky for young newcomers to astronomy, explaining what can be seen using the naked eye, binoculars or a telescope. In this book, author Robin Scagell shows the novice astronomer where to look in the sky to see a particular object, or group of objects or sights, which may be a planet, its rings or satellites, a series of lunar craters, a constellation, asteroids, meteors, a nebula, galaxy or star cluster, for example. He explains what you can expect to see with just the naked eye and describes the object in detail, giving observing tips for better viewing. A concise 'fact file' is provided for major objects, and readers can award themselves 'points' for their skill in finding the object in the first instance, with higher scores given for spotting some of its more elusive or hard-to-see features. Philip's 101 Objects To Spot In The Night Sky is illustrated in full colour throughout, with approximately 300 high-quality photographs, diagrams and star maps.
Philip's Month-by-Month Stargazing 2017 is a concise guide to the northern-hemisphere night sky, helping starwatchers to see the year's most fascinating events, whether observing with the naked eye, binoculars or a telescope. The authors have also included ideas for joining Citizen Science projects at the cutting edge of astronomical research. The guide is suitable for use between latitudes 40°N and 60°N, including Britain and Ireland, Europe as far south as Rome, and Canada and the northern USA as far south as Philadelphia. Each chapter (one for each month of the year) has a colour star map, created by Wil Tirion, showing the positions and phases of the Moon, the positions of the planets, and other useful information. Each month also includes a constellation described in detail; special events during the month, such as eclipses; a featured astronomical object, usually a deep-sky target; plus an astrophotograph, with details of how it was taken. The Solar System Almanac explains the movement of the planets, with particular attention paid to their positions in 2017. Solar and lunar eclipses, meteor showers and comets are also described. Exploring the Deep Sky provides a list of recommended deep-sky objects. The observer can use the monthly charts to discover which constellations are on view, and then use this information to plan deep-sky observing. The book concludes with an Equipment Review. Here Robin Scagell, author of Philip's Stargazing with a Telescope, provides a round-up of what's new in observing technology.
The first helium star was discovered in 1942, the first scientific meeting on the subject, however, took place in 1985. The meeting was hence long overdue for, in the meantime, a substantial amount of material had been accumulated by a rather small, but active scientific community. Hence, it appeared necessary to review the field in order to define the subject, assess its present status and discuss future developments. Hydrogen deficiency is a widespread phenomenon, occurring in a large variety of stellar and nonstellar objects. It can be readily detected in B stars as these exhibit both hydrogen and helium lines, if the elements are present in appreciable amounts. It becomes less manifest in cool stars, where the temperature is too low to excite helium and where one has to devise indirect methods for proving hydrogen deficiency. Clearly, it was not possible to discuss the whole complex of hydrogen deficiency, i.e. in both stars and diffuse matter, but rather to concentrate on the issue of helium stars.
Philip's Stargazing With Mark Thompson provides the perfect introduction to the fascinating hobby of astronomy for beginners, written by TV's favourite astronomer. With 30 years' experience in observational astronomy and helping hundreds of newcomers get started in their new hobby, Mark Thompson takes everything he has learned and leads his readers skilfully through their early stargazing experiences in this brand-new book - Philip's Stargazing With Mark Thompson. He provides a wealth of knowledge, with valuable hints and tips to aid beginners in their first steps in astronomy. Not only does Mark demonstrate great observational techniques and how to find the brighter objects in the sky, but he guides his readers through the important steps of choosing and using a telescope. This is a book that will not only act as a guide to the novice astronomer but, by drawing on Mark's own experiences, will be a companion to share in the wonders of the night sky.
The idea of holding a colloquium on Schmidt telescopes (techniques and science) originated from the observation that, in the last ten years and in spite of the remarkable developments and achievements in this field of astronomical research, there had been no specific opportunity for the experts to meet together, make the point on the state of the art, discuss and coordinate future plans. Therefore, Prof. L. Rosino, one of the pioneers in the use of wide-field telescopes, driven also by the wish of honouring the over four decades of activity of the Asiago Observatory, proposed to the Executive Committee of the International Astronomical Union to sponsor a colloquium on 'Astronomy with Schmidt type telescopes I to be held at Asiago at the end of the summer of 1983. Details about the composition of the Scientific Organizing Committee and the sponsoring organizations are given in Prof. Rosino's 'Welcome to the Participants • The granting of this proposal was the beginning of a ' number of headaches tor the members of the Local Organizing Committee, R. Barbon, F. Ciatti, P. Rafanelli and myself. If, organlzationwise, the colloquium was successful, this is truly due to the generous efforts of my colleagues of the SOC and to the efficient organization of the Linta Park, the hotel hosting the meeting.
Listing more than 500 sky targets, both near and far, in 187 challenges, this observing guide will test novice astronomers and advanced veterans alike. Its unique mix of Solar System and deep-sky targets will have observers hunting for the Apollo lunar landing sites, searching for satellites orbiting the outermost planets, and exploring hundreds of star clusters, nebulae, distant galaxies, and quasars. Each target object is accompanied by a rating indicating how difficult the object is to find, an in-depth visual description, an illustration showing how the object realistically looks, and a detailed finder chart to help you find each challenge quickly and effectively. The guide introduces objects often overlooked in other observing guides and features targets visible in a variety of conditions, from the inner city to the dark countryside. Challenges are provided for the naked eye, through binoculars and the largest backyard telescopes.
Featuring recent discoveries and state-of-the-art space photography, an atlas illustrates all that science has revealed about constellations, the evolution of stars and galaxies, and the planets in the solar system.
The XXth General Assembly of the International Astronomical Union was held in Baltimore, Maryland USA from August 02 to 11, 1988. The Inaugural Ceremony on August 02 was held in the presence of representatives of the United States Governn:ent, t~e S~ate of Maryland, the City of Baltimore and the host institution -the Johns Hopkins Umverslty- as well as of the National and Local Organising Committees. The scientific programme maintained the high standards of the Union and the scientific proceedings may be found either in this volume or in volume 8 of Highlights of Astronomy. The scientific programme was organised by the 40 Commission Presidents and coordinated by the General Secretary (1985-1988), Dr. J.-P. Swings. The local arrangements were effectively made through the National Organising Committee under the Chairmanship of Prof. F. Drake and the Local Organising Committee under the co-Chairmanship of Prof. A. Oavidsen and Dr. R. Giacconi. The smooth day to day operation of the meeting resulted from the incomparable dedication of Karen Weinstock and Harold Screen.
