planetarium solution that would represent a paradigm shift in how planetariums
can become destination spots to educate and entertain visitors. Since its surface can't be
observed directly from Earth, scientists turned to Spitzer's infrared eyes to
measure its size. They calculated the amount of reflected, visible light observed
by Hubble and found Tempel 1 reflects only four percent of the sunlight that
falls on it.spitzer.
