science
behind
a
rare
astronomical
event:
Venus
crossing
the
Sun?s
disk
for
about
seven
hours
on
June
8,
2004,
an
event
not

orbiting
stars
outside
our
Solar
System.

This product illustrates how scientists learn about the composition of an asteroid by studying energy and neutrons that emanate from it. The Dawn spacecraft contains three instruments -- the Gamma Ray and Neutro Detector (GRaND), the Visible Infrared Spectrometer, and the Framing Camera -- that will provide answers to questions about the formation and evolution of the early solar system.

This
product
uses
a
collection
of
Hubble
Space
Telescope
(HST)
images
of
galaxies
in
the
Coma
Cluster,
and
engages
students
in
an
inquiry-based
learning
activity
studying
the
evolution
of
galaxies
in
dense
clustered
environments.
Students
learn
the
basics
of
galaxy
classification
by
making
use
of
the
HST
images
to
discover
a
"morphology-density
effect,"
and
will
then
make
