Sky & Telescope - October 2023 - 20

CITIZEN SCIENCE BIG LEAGUES by Madison Goldberg
T
he James Webb Space Telescope's first images captivated
the world last year, revealing the billowing folds
of a stellar nursery, a dazzling rendezvous of galaxies,
and other cosmic treasures in stunning detail (S&T:
Nov. 2022, p. 12). But a few hundred miles above the buzz
on Earth, another famous telescope continued to quietly go
about its business.
The Hubble Space Telescope, our trusty observer of deep
space, recently rounded out three decades in service, and it's
still snapping photos. Even as many of us turn our attention
to a younger observatory, scientists are working to make the
most of this old one.
One of the projects that has helped do that is " Gems of
the Galaxy Zoos. " Zoo Gems is an unusual project: Rather
than being a targeted proposal for a specific research study, it
pulled together an assorted list of galactic targets to plug the
holes in Hubble's schedule. Although it grew out of an online
citizen-science effort, Zoo Gems went beyond volunteers'
usual task of clicking through galaxies and sorting them by
shape. Instead, it drew on a decade's worth of curiosity and
conversation among " Zooites " to turn Hubble's gaze on some
of the universe's most mysterious inhabitants.
Cosmic Community
For astronomers, enlisting the public can bring huge practical
benefits. As ground-based telescopes churn out gargantuan
maps of the sky, for example, volunteers can help sift
through the data (S&T: Jan. 2023, p. 20).
The Galaxy Zoo project was born in 2007 to lend a hand
- or, as it grew, many thousands of hands. In its early days,
the online platform showed users deep-space images from
the Sloan Digital Sky Survey and posed some simple questions:
Is the galaxy in the image a spiral? Are its arms clockwise
or counterclockwise?
But it soon became clear that some Zooites wanted to
do more than just classify galaxies. " I might possibly have
believed the breadth of interest at the outset, " says William
Keel (University of Alabama), a member of Galaxy Zoo's science
team. " But the depth that some of the volunteers went
into, I don't know if I would have bought it to begin with. "
The platform's discussion forum buzzed with activity:
users pondering odd galaxies, asking questions, writing
space-themed limericks. Christine Macmillan, a retired plant
scientist and planetarium presenter, joined Galaxy Zoo in
2008 and eventually became a forum moderator. She dug
Unearthing Galactic
Astronomy enthusiasts and
scientists join forces to help
fill Hubble's free time.
