Welcome!
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!
