Book Description
IAU Colloquium No. 71 had its immediate origins in a small gathering of people interested. in the optical and UV study of flare stars which took place during the 1979 Montreal General Assembly. We recognized that a fundamental change was taking place in the study of these objects. Space-borne instruments (especially lUE and Einstein) and a new genera tion of ground-based equipment were having a profound effect on the range of investigations it was possible to make. To extract maximum benefit from these new possibilities it would be necessary as never before to have good communication with colleagues in other disciplines, for instance,. with atomic and solar physicists. Similarly, studies of phenomena associated with the outer atmospheres of the late-type stars could now hope to give significant insights into certain aspects of solar activity. So, in view of the wide range of backgrounds of those participating, the meeting had an unusually high proportion of invited reviews while most of the contributed papers were presented as posters. It is gratifying that in the short time since the meeting a good deal of correspondence has been received from participants remarking on the success of this format. Once the decision had been taken in principle to hold the meeting, a very considerable amount of work fell on the two organizing committees, viz. the Scientific and Local Organizing Committees. The Scientific Organizing Committee was chaired by D.J. Mullan and consisted of A.D.

Book Description
Gliese 581 is a red dwarf star some 20.3 light years from Earth. Red dwarfs are among the most numerous stars in the galaxy, and they sport diverse planetary systems. At magnitude 10, Gliese 581 is visible to amateur observers but does not stand out. So what makes this star so important? It is that professional observers have confirmed that it has at least four planets orbiting it, and in 2009, Planet d was described in the letters of The Astrophysical Journal as “the first confirmed exoplanet that could support Earth-like life.” Under a Crimson Sun looks at the nature of red dwarf systems such as Gliese as potential homes for life. Realistically, what are prospects for life on these distant worlds? Could life evolve and survive there? How do these planetary surfaces and geology evolve? How would life on a red dwarf planet differ from life on Earth? And what are the implications for finding further habitable worlds in our galaxy? Stevenson provides readers with insight into the habitability of planets and how this changes as time progresses and the central star evolves. Explore with him in this engaging, fascinating book the possibilities for finding life, from bacteria to more complex and even intelligent organisms, on red dwarf system planets.

Book Description
Twenty years after Isaac Asimov praised Timothy Ferris's GALAXIES as the most beautiful book ever published, MAGNIFICENT UNIVERSE establishes a new standard of excellence in depicting space. No other book even comes close. Ken Croswell takes us across the known universe - from the planets of the Sun to the stars of the Galaxy to the galaxies of the Cosmos. This is, simply, the most beautiful astronomy book in existance. The exploration of space by telescope and space probe continues at an exhilarating pace. While many think that only the Hubble telescope has new photographs of the heavens to offer, MAGNIFICENT UNIVERSE draws not only on Hubble but on fifty different sources. With the latest, stunning astronomical vistas, this lavish book allows us to experience the universe as never before.

Book Description
Some 70 papers present the flare star problem from both a physical and evolutionary aspect, and represent an interaction between investigators working on flare stars in clusters and associations, and those working on the UV Ceti stars in solar vicinity. The variety of perspectives reveal a physical similarity among several non-stable phenomena, and suggest that the different manifestations of stellar activity result from the release of some unknown kind of energy in the outer layers of young stars. The papers deal not only with different aspects of flare stars, but also with such related objects as T Tauri stars, fluors, and Herbig-Haro objects.

Book Description
Looking up into the Heavens on a clear night under a dark sky, we can easily fool ourselves into thinking that the brightest stars we see are those closest to us. The reality could not be more different! In fact, 19 of the 25 closest stars to the Sun are invisible to our naked eye, and many are actually fo faint that even with the modest equipment owned by most amateur astronomers, they can be supremely difficult to find. Observing the Nearest Stars takes the reader on a one-year guided tour through the region of the Milky Way galaxy closest to our own solar system, concentrating on practical hints at observing this region for one's self. 63 color illustrations and detailed star charts guide the viewer to find for themselves every star within 12 light years of the sun and visible from the Continental United States.

Book Description
One does not need to travel to distant lands to go on a pilgrimage. In "Eyes to See", the reader is led on a year-long pilgrimage to those stars nearest to our own sun without leaving one's own back yard, only to discover unsuspected recesses within his own soul. Rather than a journey to T.S. Eliot's "vacant interstellar spaces", he discovers community, perspective, and purpose.
