astronomical phenomena: solar and lunar eclipses,

meteor showers, and comets.

ANNOUNCING: The November 2, 2020 issue of Linn's Stamp News features a short article by Linn's editor Michael Baadke on the Astronomy Study Unit.

The Astronomy Study Unit now has a Facebook Group

The American Topical Association has a new website

and has released a new book: Albert Einstein on

Stamps: A Catalog, an in-depth exploration

of how one of the world's most famous scientists has

been depicted in modern postage stamps. Check the ATA site for details and ordering.

There are several web sites associated with astrophilately. Here are a few:


World's Oldest Astronomy Stamps

A great website listing stamps issued from before 1940 to 1956.


Astronomy and Cosmology on Stamps

An excellent compilation of the history of astronomy through stamps (from the University of Buffalo (NY) Libraries).


Collect Space Stamps

Mostly geared towards space stamps, but also lists many astronomy-themed stamps, particularly those associated with astronomical observations, such as the Hubble Space Telescope.


Un-Manned Space Philately

An amazing site of a catalog of stamps and launch covers related to scientific research, including solar research, astrophysics, and planetary exploration all organized by theme. The site is managed by Garry Toth and Dan Hilger, authors of the book Space Weather - A Philatelic Journey, available from the ATA.

Physicists and Physics on Stamps

Not fancy, but does list quite a number of physicist-themed stamp issues, many of whom are also astronomers and astrophysicists. A similar collection can be found here and here.


Weebau Space Stamp Catalog

Quite an extensive listing by topic and country of space and astronomy stamps.


Science on Stamps

Not exactly a website and not exactly devoted to astronomy, but this downloadable PDF of over 148 pages details an exhibit on science on stamps from the University of Buffalo libraries. Many descriptions of astrophysics, astronomy, and scientists associated with the discipline.


Astro Space Stamp Society

The Astro Space Stamp Society, based in the UK,  is dedicated to everyone who collects space stamps, postcards, covers, signed autographs from astronauts to astrophilatelic memorabilia or just enthusiasts on the Space hobby. The Astro Space Stamp Society publishes the magazine, Orbit.

Space Study Unit

The Space Study Unit of the American Topical Association, featuring many overlapping themes with the Astronomy Study Unit.


Chemistry and Physics Study Unit

Another study unit of the American Topical Association, which also features overlapping themes with the Astronomy Study Unit.


Astrophilately Book!

Calling all astrophiles! There is a fantastic book devoted to astronomy and astrophilately: Stamping Through Astronomy (2013) by Renato Dicati (ISBN 978-88-470-2828-9).
