Light Years Away covers the wonderful things of our universe and the possibilities beyond our visible range. As the name suggests most of the subject matters of the book are of distant objects like our neighbouring stars, star clusters, nebulae, galaxies, galaxy clusters and superclusters. In the final chapters the possibilities beyond the observable limit and beyond our universe have been looked at carefully. But the facts of solar system and earth have not been ignored. The whole view of the creation has been presented in a lucid format. The basic questions that we encounter like, where is the end (boundary) of the universe, what can be the nature of the extra universal things, is light the fastest; why we are unable to explain the universe etc have been addressed in a scientific and logical but unsophisticated way. Of course some back ground in the subjects like physics and astronomy can help in the better understanding into the matter. But for any enthusiast of space and cosmos irrespective of the back ground and age Light Years Away will be a satisfactory text.

Astronomy and Astrophysics Abstracts, which has appeared in semi-annual volumes since 1969, is de voted to the recording, summarizing and indexing of astronomical publications throughout the world. It is prepared under the auspices of the International Astronomical Union (according to a resolution adopted at the 14th General Assembly in 1970). Astronomy and Astrophysics Abstracts aims to present a comprehensive documentation of literature in all fields of astronomy and astrophysics. Every effort will be made to ensure that the average time interval between the date of receipt of the original literature and publication of the abstracts will not exceed eight months. This time interval is near to that achieved by monthly abstracting journals, com pared to which our system of accumulating abstracts for about six months offers the advantage of greater convenience for the user. Volume 6 contains literature published in 1971 and received before March 15, 1972; some older liter ature which was received late and which is not recorded in earlier volumes is also included.
