Bringing the universe down to Earth…
Dennis L Mammana
Astronomer
For
nearly
five
decades,
I’ve
been
privileged
to
share
the
wonder
and
mystery
of
the
universe
with
audiences
around
the
world―through
my
public
lectures
and
workshops,
my
popular
astronomy
writings,
celestial
photography,
unique
night
sky
tours
and
my
exciting
astronomy
enrichment
travel
programs
to
some
of
the
most
exotic
locations
on
our
planet.
I hope you enjoy exploring my website, and that you will follow and chat with me online!
