With Astronomy magazine editors David J. Eicher and Michael E. Bakich

Adler Planetarium • Field Museum • Fermilab • Yerkes ObservatoryBACKSTAGE PASS

WWW.ASTRONOMY.COM 49

Obviously, we cannot hope to cover institutions like Adler

Planetarium, the Field Museum, Fermilab, and Yerkes Observatory

in depth by dedicating a scant two pages to each site. However,

we do have a way for you to experience them at length — and in the

comfort of your own home.

Astronomy Backstage Pass:

Chicago is a three-hour informal

account of our visit to these

wonderful astronomy facilities

in the Chicago area. Along the

way, you’ll meet scientists,

lecturers, and curators; you’ll

see equipment, books, and

artifacts that are not on public

display; and not only will you

learn about the past of these

historic institutions, but what

their futures hold as well.

YOUR OWN PRIVATE TOUR

This copper cavity accelerates particles to high energy. A beam of particles
enters and travels in sync with an 805-megahertz wave, gaining speed and
energy. Fermilab has 30 strings of such cavities that can accelerate protons
to three-quarters the speed of light. MICHAEL E. BAKICH

is the main building of the

Fermi National Accelerator

Laboratory, founded in 1967.
