New kind of astronomical object and astrophotography

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - The tight cluster of stars surrounding a supermassive black hole after it has been violently kicked out of a galaxy represents a new kind of astronomical object and a fossil record of the kick. See article.
g Life - In living organisms, chiral compounds such as amino acids and sugars exist as single enantiomers. What is the origin of this exclusive preference? Japanese scientists believe that achiral molecules from space could provide the answer. See article.
g Cosmicus - Neil Armstrong's hometown is going all out for the 40th anniversary of the frst moon walk. See article.
g Learning - Just take a moment and guess: from how far away can a camera, whether point and shoot or SLR, still take good pictures of the intended subject? 1,000 feet? Go farther. A mile? No problem. How about light years? Yes, cameras can literally see light years away. While most photographers tend to focus (bad humor, I know) on terrestrial objects, a small group of photographers reach for and capture the stars on their camera's sensor. These people are astrophotographers, and you can be one of them, too. See article.
