and now for some final thoughts on
looking
up 400 years ago Galileo a mathematician
in Venice Italy built a telescope of his
own design and used it in a way that
hardly anybody else at the time thought
of instead of looking at birds or spying
on neighbors he looked up he looked up
at the Sun moon and stars then and there
began a 4 Century Legacy of discovery
that would permanently transform our
relationship to the
universe over these years we went from
thinking that Earth was the object of
creation positioned at the center of all
motion to discovering that Earth is but
one of many planets that the sun is one
of hundreds of billions of stars in the
Milky Way galaxy that the Milky Way
galaxy is but one of a 100 billion
galaxies in the
universe sounds depressing but you know
what else telescopes have shown us about
our place in the universe they've shown
us that we're not somehow separate from
the cosmos we're part of it the atoms of
our bodies were forged in the fires of
stars that burned billions of years ago
exploding these ingredients into space
for subsequent generations of stars to
use this Atomic and molecular kinship
connects the sun to every other star in
the galaxy galxy it connects Earth to
every other planet in orbit around them
and it connects us to any life that may
Thrive there so as we say in my field of
science it's always best to keep looking
up and that is the cosmic
perspective and now we'd like to hear
