Welcome!
Bringing the universe down to Earth…
Dennis L Mammana
Astronomer
For more than 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 this
website, and that you will follow and chat with me online!
