2.  Currently pursuing a doctorate in clinical psychology
at the Pacifica Graduate Institute in Southern
California, Jordan Perzik sustains a lifelong interest in
astronomy. Jordan Perzik frequently attends lectures
offered by institutions such as the Los Angeles
Astronomical Society and the Griffith Observatory. A
pioneering institution, the Griffith Observatory is open
for free to the public and offers live Internet
broadcasts of major planetary events.
On January 23, 2015, the Griffith Observatory
broadcast the Jupiter triple-moon shadow transit. This
rare event involved three of Jupiter’s Galilean moons:
Europa, Callisto, and Io.

3.  These large satellites can typically be seen
on Earth through the use of telescopes and
high-powered binoculars, but the January
event was special in that the three moons’
shadows fell on the cloud tops of Jupiter
and created a spectacular view of both
the moons and their dark shadows. The
event, last witnessed in the United States in
late 2013, lasted for only 24 minutes. The
next time such an event will be viewable
from the United States will be nearly two
decades from now, in 2032.
