Galaxy Map, created by Kevin Jardine, is a detailed scientific resource explaining how astronomers measure distances to objects within the Milky Way using parallax and related surveying techniques. The site covers exotic galactic objects like black holes, microquasars, and supernova remnants, with dedicated sections on hydrogen mapping, velocity mapping, and tools like VLBI and the Hipparcos and Gaia satellites.

The official University of Maryland archive for NASA's Deep Impact mission, which sent a spacecraft to collide with comet Tempel 1 in 2005 and later extended its mission as EPOXI to observe comet Hartley 2 and distant exoplanets. The site preserves science results, image and video galleries, team member profiles, and mission history through the spacecraft's final loss of contact in 2013.
https://arpgalaxy.com/
A comprehensive amateur astronomy resource dedicated to Halton C. Arp's Atlas of Peculiar Galaxies, cataloging all 338 peculiar and interacting galaxy entries with supporting data, imagery, and observing guidance. Built by and for amateur observers, the site bridges professional archival photography from the Palomar 200-inch telescope with modern amateur CCD imaging to show that anyone with a backyard telescope can observe these remarkable objects.

Skychart, also known as Cartes du Ciel, is a free open-source planetarium program that lets users draw detailed sky charts using star and nebula catalogs while also displaying the positions of planets, asteroids, and comets. This multilingual wiki serves as the official documentation and download hub for the software, supporting Linux, Windows, and macOS with both stable and beta releases.
