May 2010: Exploring the galaxy-black hole connection
This month's issue of Astronomy magazine probes the likely relationship between massive galaxies and the enormous black holes at their cores, examines astronomers' latest efforts searching for life beyond Earth, reviews Vixen's AX103S refractor telescope, provides a beautiful poster displaying our Milky Way Galaxy in tremendous detail, and more.

|WAUKESHA, Wis. — As hard as it may be to fully understand family dynamics in humans, some cosmic families have proven even harder to comprehend. One such relationship is the possible one between large galaxies and the supermassive black holes that have turned out always to lurk in their centers. |
In "Exploring the galaxy-black hole connection," Contributing Editor Steve Nadis explains the history behind this unexpected link and several competing theories as to why it exists. Although astronomers have worked on this problem for almost 2 decades, no clear consensus has yet emerged.
"[University of Michigan astronomer Douglas] Richstone regards the current state of affairs as an 'interesting mess,' " Nadis writes. "Scientists are learning plenty of new things, and some of them might lead to an answer, [Richstone] says." Whatever the case, the tremendous amount scientists are learning about galactic dynamics ensures that the journey to find the answers will be as revealing as the answers themselves.
Pick up the May issue of Astronomy, on newsstands April 6, to learn the details of current theories that explain the connection and what they mean for galactic evolution.
"The new search for life in the universe"
As astrobiologist Christopher Chyba writes, "For thousands of years, people have wondered if there are other worlds like Earth that support living organisms." Even though we're still not certain of the answer, the Princeton professor explains just what made life on Earth successful and how we can use that knowledge to better search the cosmos for similar environments. Whether or not life exists elsewhere may be just as important as understanding why.
"Vixen's new refractor outperforms its specs"
Contributing Editor and Columnist Glenn Chaple's first foray into high-end observing leaves him "spoiled" for the razor-sharp, flawless, and sleek optics of this "Ferrari" of telescopes, Vixen's AX103S.
"Axel Mellinger's Milky Way mosaic"
Gaze upon our Milky Way Galaxy as never before with this bonus poster foldout displaying thousands of famed astrophotographer Axel Mellinger's images in a huge, seamless mosaic. The result is unique in both its scientific value and its esthetic beauty.
