Progress in Determining the Space Orientation of Starssion and observational procedure with which this theory can be tested. Presently available data is presented, and observing stars are outlined. The importance of this determination to the methods of detecting extrasolar planetary systems is further developed, and a few examples are given.

Systematic Aspects of Direct Extrasolar Planet Detectionckground of diffracted and scattered starlight. The very long exposure time required to achieve an adequate signal-to-noise ratio will make their detection infeasible. For a future telescope, a 16-fold increase in either the smoothness or the collecting area of the optics would reduce the exposure t

Water: An Absolute Requirement for Lifengs have two kinds of low-entropy materials, clean liquid water of low energy, and carbohydrate of high energy. .. Water is absolutely important for life not only as the place where the elementary bio-process proceed, but also as the low-energy and low-entropy material indispensable for entropy elimination from the concerned living system.
