Although transits of planets across the Sun are rare (only Mercury and Venus orbit the Sun closer than us, and so can transit the Sun's disc) amateur astronomers can observe, record and image other kinds of transit, which are very much more frequent.
The purpose of this book is to introduce the reader to the numerous safe methods of observing the Sun and solar eclipses, and to suggest objects and features to observe and observing programmes to follow.
Because today's amateur astronomical telescopes are both powerful and affordable, spectroscopy - once the province of professionals - is becoming more and more popular.
In 1996 Meade, the world's largest astronomical telescope manufacturer, introduced the ETX, a low-cost and genuinely portable instrument capable of results close to the theoretical limits of optical performance.
Amateur astronomy is becoming more and more popular, mostly because of the availability of relatively low-cost astronomical telescopes of superb quality - commercially-made Schmidt-Cassegrain and Maksutovs.
One of the wonderful aspects of the US Manned Spaceflight Program was the opportunity for people around the entire globe to participate in one of man's greatest adventures.
The 3-D Atlas of the Stars and Galaxies shows the stars and A star at twice that distance (and showing a parallax of one-half galaxies in three-dimensional space, with the third of a second of arc) is said to be at a distance of'two parsecs'; one dimension- distance- dire.
Interested students in the natural and engineering sciences, as well as high school graduates, instructors, teachers, and amateur astronomers, will find a valuable overview of the physics of stars in this book.
This third edition of Malcolm Longair's highly acclaimed textbook is an up-to-date text on astrophysical cosmology expounding the structure of classical cosmological models from a contemporary viewpoint.
This textbook provides students with a solid introduction to the techniques of approximation commonly used in data analysis across physics and astronomy.
