Jim Kaler's comprehensive guide to stellar spectra covers everything from absorption and emission lines to the Doppler effect and spectral classification, all richly illustrated with images of rainbows, nebulae, and spectrograms. Part of Kaler's broader STARS educational project hosted at the University of Illinois, this deep-dive reference explains how astronomers decode the physical and chemical nature of stars through the light they emit.

An interactive data visualization called 'The Population of Space' charts every human spaceflight from Yuri Gagarin in 1961 through 2014, grouping missions by launch vehicle and coloring them by historical era. Created in honor of the 45th anniversary of Apollo 11, it offers a fascinating way to explore how long humans have spent in space, which nations sent them, and how the shift from Soviet stations to the International Space Station shaped our continuous presence off-world.
https://exameter.neocities.org/
A personal site titled '105.7 Light Years' on Neocities, offering desktop and mobile versions of its content with accompanying photos. The light-year themed title and structure suggest an astronomy or space-related focus, though the site is currently partially broken.
https://radiojove.gsfc.nasa.gov/library/newsletters/2008Dec
The December 2008 issue of The JOVE Bulletin covers NASA's Radio JOVE Project, a program enabling students and educators to build simple radio telescopes and observe solar and planetary radio emissions. Highlights include field reports of Jupiter radio storm observations, a gallery of radio spectrograms, and news about Radio-SkyPipe 2 software for amateur radio astronomy.
