Websites

ABCs of Distance: https://www.astro.ucla.edu/~wright/distance.htm. Astronomer Ned Wright (UCLA) gives a concise primer on many different methods of obtaining distances. This site is at a higher level than our textbook, but is an excellent review for those with some background in astronomy.

American Association of Variable Star Observers (AAVSO): https://www.aavso.org/. This organization of amateur astronomers helps to keep track of variable stars; its site has some background material, observing instructions, and links.

Friedrich Wilhelm Bessel: https://messier.seds.org/xtra/Bios/bessel.html. A brief site about the first person to detect stellar parallax, with references and links.

Gaia Satellite: https://www.esa.int/Science_Exploration/Space_Science/Gaia. News from the Gaia mission, including images and a blog of the latest findings.

Hipparcos: https://www.cosmos.esa.int/web/hipparcos. Background, results, catalogs of data, and educational resources from the Hipparcos mission to observe parallaxes from space. Some sections are technical, but others are accessible to students.

John Goodricke: The Deaf Astronomer: https://www.bbc.com/news/magazine-20725639. A biographical article from the BBC.

Women in Astronomy: https://bit.ly/astronomywomen. A guide to readings and websites, with more about Henrietta Leavitt’s and other women’s contributions to astronomy and the obstacles they faced.
