The Arp Atlas of Peculiar Galaxies
Jeff Kanipe and Dennis Webb
In addition to star clusters and nebulae, galaxies are one type of deep sky object amateur astronomers enjoy searching for and observing. It is amazing that even with modest telescopes, we can study many of these objects even though they lie at vast distances beyond our own Milky Way galaxy. In the 1930s astronomer Edwin Hubble devised a classification system for galaxies based on shape, be it elliptical, barred spiral, or elliptical spiral. As more galaxies came under scrutiny it became obvious that many simply do not fit into Hubble’s system. In 1966 astronomer Halton “Chip” Arp highlighted the predicament by publishing his Atlas of Peculiar Galaxies, listing 338 oddball galaxies with such curious features as heavy arms or detached segments. There are ellipticals hanging onto spirals for dear life, galaxies with jets, galaxies with repelling spiral arms, a true cosmic Ripley’s Believe It or Not!
This newer book, the Arp Atlas of Peculiar Galaxies by Jeff Kanipe and Dennis Webb, authors of Willman Bell’s Annals of the Deep Sky series, chronicles the history of Halton Arp and guides amateur astronomers through Arp’s 338 galaxies with sky charts, amateur images of each galaxy, and notes by experienced observers on the remarkable features of these faraway gems.
The Lamplighter Library will not be accessible during the renovation of our usual meeting venue, the star theatre, but in the meantime a selection of books will be available outside the IMAX theatre before and after each meeting!
Check out this book and hundreds of other books, at The Lamplighter Memorial Library, just off the entrance to the star theater.
