This book presents the amateur with fine examples of astronomical sketches and step-by-step tutorials in each medium, including pencil, pen and ink, chalks and pastels, painting and computer graphics programs. This unique book can teach almost anyone to create beautiful sketches of celestial objects by following simple, illustrated, step-by-step instructions. Readers can select a chapter related to their preferred class of object, and rapidly learn techniques in several media. Each chapter contains useful information regarding equipment, techniques for preserving and archiving sketches, and suggestions for accurate record keeping.

Suitable for any amateur astronomer, this work includes an introduction to home astronomy as well as a fill-in logbook for charting your discoveries. It teaches how to navigate the night sky, what equipment you need, and what to look for and when.

Taking notes on astronomical observations is a valuable tool and time-honored tradition for professional and amateur astronomers alike. We hope that this journal serves you well in recording your astronomical observations and sharing your experiences with others. This 8x10" journal includes 100 blank observational logs to enhance your skygazing experience. Designed by Camp Galaxy, the elegant log format included here allows you to record details about the object or objects being observed and the site and conditions at the time of observation. Five full pages for notes and reflections are also included at the end of the journal. Paperback-bound with a charming and beautiful cover, this journal is sure to be a lasting record of your unique observations. This lovely astronomy log also makes a wonderful gift for the star gazer in your life.

There are solar eclipses and lunar ones too. Space vehicles passing overhead. Nighttime skies so bright they are awesome. Go out and look. Take your 'scope or binoculars - whatever, just go look. Use the Sky Gazing Journal to write down and draw what you see. If the movies Interstellar or Gravity inspired you, then get a Star Gazing Journal. Make notes about the Rosetta landing. Awesome stuff. Now you don't have to make astronomy observation notes on little scraps of paper or in funky notebooks. Record your sky viewing observations in an orderly way with this easy-to-use stargazing journal. Each page includes blank areas that allow you to sketch exactly what you're seeing in the night sky. You can also keep track of the date, time, lunar phase, longitude, latitude, sky conditions, and the equipment used. Make note of how many meteors you see during the Leonid and Perseid meteor showers. Follow a comet over the course of many nights. Or, just jot down how spectacular the night sky was on a certain date. You can even make note of the International Space Station (ISS) as it passes over your location. It's awesome to observe! Each time it passes, it's on a different trajectory. There are many celestial events to observe, in addition to the stars, constellations, and planets. With this stargazing journal, you'll be able to plan ahead and then record your observations. It's an astronomy journal you'll keep for years!

Third edition textbook for use on advanced courses on stellar physics.

Molecular line emissions offer researchers exciting opportunities to learn about the evolutionary state of the Milky Way and distant galaxies. This text provides a detailed introduction to molecular astrophysics and an array of useful techniques for observing astronomical phenomena at millimetre and submillimetre wavelengths. After discussing the theoretical underpinnings of molecular observation, the authors catalogue suitable molecular tracers for many types of astronomical regions in local and distant parts of the Universe, including cold gas reservoirs primed for the formation of new stars, regions of active star formation, giant photon-dominated regions and near active galactic nuclei. Further chapters demonstrate how to obtain useful astronomical information from raw telescope data while providing recommendations for appropriate observing strategies. Replete with maps, charts and references for further reading, this handbook will suit research astronomers and graduate students interested in broadening their skill to take advantage of the new facilities now coming online.

For the last twenty years astronomy has been developing dramatically. Until the nineteen-fifties, telescopes, spectrometers, and photographic plates consti tuted a relatively simple set of tools which had been refined to a high degree of perfection by the joint efforts of physicists and astronomers. Indeed these tools helped at the birth of modern astrophysics: the discovery of the expan sion of the Universe. Then came radioastronomy and the advent of electronics; the last thirty years have seen the application to astrophysics of a wealth of new experimental techniques, based on the most advanced fields of physics, and a constant interchange of ideas between physicists and astronomers. Last, but not least, modern computers have sharply reduced the burden of dealing with the information painfully extracted from the skies, whether from ever scarce photons, or from the gigantic data flows provided by satellites and large telescopes. The aim of this book is not to give an extensive overview of all the tech niques currently in use in astronomy, nor to provide detailed instructions for preparing or carrying out an astronomical project. Its purpose is methodologi cal: photons are still the main carriers of information between celestial sources and the observer. How we are to collect, sample, measure, and store this infor mation is the unifying theme of the book. Rather than the diversity of tech niques appropriate for each wavelength range, we emphasize the physical and mathematical bases which are common to all wavelength regimes.
