... Seeking a splendid escape to the beach or the cool breezes and green hills of the foothills and mountains of the northeast can offer a chance to take a longer look at the summer sky. ... StarQuest Memories. StarQuest was a blast this year! ... The observing at StarQuest, especially on Saturday night, was worthy of pulling an all-nighter, and several of us had our eyepieces and CCD cameras working all night along (including Brian Van Liew and Bob Vanderbei with their CCDs). ... Dark Skies! ...

Journal of the Amateur Astronomers Association of New York August 2007 Volume 55 Number 8, ISSN 0146-7662 EYEPIECE understand dark matter is to locate it, and observe its structure and function in the universe, and this is what Massey and his team set out to do. ... August's Planets. ... By splitting the half million background source galaxies it observed into discrete redshift bins, Massey's team could visualize a three-dimensional map of the dark matter surrounding them. ...

... Printed in the U.S.A. ON THE CONSTANCY OF THE PHOTON INDEX OF X-RAY SPECTRA OF 4U 1728-34 THROUGH ALL SPECTRAL STATES Elena Seifina1 and Lev Titarchuk2 1 2 ,3 ,4 Sternberg Astronomical Institute, Moscow State University, Universitetsky Prospect ... We find that the X-ray broadband energy spectra of 4U 1728-34 during all spectral states can be modeled by a combination of a thermal (blackbody-like) component, a Comptonized component (which we herein denote as COMPTB), and a Gaussian component. ...
