An archived recreation of Dr. Sten Odenwald's legendary 'Astronomy Cafe' website from circa 2001, once a destination where a professional astronomer answered thousands of public questions about space, the universe, and infrared astronomy. The site preserves a nostalgic snapshot of early web science outreach, featuring Dr. Odenwald's books, his 'Ask the Astronomer' feature, and philosophical explorations of concepts like 'nothing' and the Big Bang.

Winchell Chung (aka Nyrath the nearly wise) maintains this ambitious 3-D starmap project dedicated to the golden age of science fiction and real astronomical data. Inspired by E.E. 'Doc' Smith's classic space operas, the site blends scientific accuracy with a deep love of the stars to create interactive three-dimensional maps of nearby stellar neighborhoods.

Clark M. Thomas offers a detailed analysis of comet imaging techniques, comparing amateur astrophotographer Damian Peach's stunning wide-field ISON image against the professional Subaru telescope's shot of Comet Lovejoy. The article makes a compelling case for tracking background stars rather than the comet itself, arguing that the resulting sharp stellar fields and visible deep-sky objects produce the most visually rewarding comet photographs.
