- Among the more than 5,500 planets circling other stars, the first ones in the Habitable Zone could be like our own worlds.
- What does it take to find a new world?
- How to read the information encoded in light to characterize a new world
Ten Worlds That Shook Science
- What were the ten exoplanets that were the biggest surprises, and how did they shake our worldview? From worlds covered in lava oceans, to worlds orbiting stellar corpses, to the intriguing worlds next door that might just be like ours, we’ll dive into the ten worlds that shook science.
- Top Ten Things About New Worlds on our Cosmic Horizon: Since the first detection of a planet circling another star about 29 years ago, we have found another world on average every other day! This incredible rate of discovery has revealed some of the secrets of these new worlds—here are the top ten, from lonely wanderers in the cosmos to billions of possible worlds like ours.
Why We Live in a Golden Age of Space Exploration
- We live in a golden era of exploration. With more than 5,500 detected planets circling other stars, our view of the night sky is changing profoundly. We have started on a new epoch of exploration, and the worlds we have discovered so far are only the tip of the iceberg of what is to come, including the discovery whether we are alone or not.
- How do we find these new worlds? From wobbling stars to the slight dimming of a star, the light we catch in our telescopes carries the secret of the cosmos, if you know how to read it.
- The speed limit of light lets us explore the cosmic past and see our universe like when it was young, but that also means, that everything you see on the night sky has already happened. However, this gives you a personal connection to the cosmos, a star that sent out its light the year you were born, arriving tonight.
Solar Eclipses and the Secrets Eclipses Tell About New Worlds on Our Cosmic Horizon
A total solar eclipse will paint a spectacular picture on the sky, where Earth, the moon, and the sun highlight the fascinating dynamics of our cosmos. But eclipses not only reveal the movement of a planetary system but also allow us to explore new worlds and exoplanets circling other stars. Eclipses are revolutionizing our view of the cosmos.
Spaceship Earth (Celebrating Earth Day)
Earth Day, which is celebrated annually on April 22nd, is the largest civic event in the world, with over a billion people participating each year. When we build a spacecraft we meticulously need to make sure that the resources are perfectly recycled and the life support system is perfectly maintained. In this talk, we will walk through such a future spacecraft and then look out of the window and realize that Earth is our gigantic spaceship in the cosmos. A shift in thinking, about Earth as such a spaceship and the biosphere as the life support system, will help us protect our beautiful planet.
Where are the Aliens?: The Thousand Ways That Earth Has Blown Its Cover
- Searching for life in the cosmos demands the questions—where would we be the aliens? Which places in the cosmos have just the perfect spot to find us? And is there a time limit to spotting other worlds before they again disappear from our view? Here we answer both questions and the answers are surprising—disclaimer, you might feel watched…
- How we find new worlds
- How the speed limit of light allows us to decipher the history of the cosmos
- How to identify the stars that could see Earth as an alien world
Could Your Favorite Science Fiction World Be Real?
- From outrunning the sunrise on Crematoria in The Chronicles of Riddick movie, Water Worlds, to watching the sunset under two stars on Tatooine in Star Wars, science fiction is full of fantastic worlds. Could some of them be real? And are there even stranger worlds science fiction has not even thought about yet?
- Let’s talk about planets circling other stars that are even stranger worlds that science fiction has not even thought about yet.
- How do we find these worlds and how do we know anything about them?
Practical Tips for Everyone From a Unicorn/Woman in Science
How not making copies the first time you are in an engineering meeting, to being able to drink terrible coffee sometimes, just allows you to make a bit more space for your ideas in an environment that is not used to you speaking up.

“Professor Lisa Kaltenegger appeared with us for the 12th gathering of The Nantucket Project where she wowed the audience with her ideas and presentation. Over 500 people went on a wild ride to the cosmos, dreamed of possibilities both finite and infinite, and were brought back down to Earth with a healthy dose of humanity as we learned from and laughed with Lisa…It was exactly what was needed for the gathering – a chance to imagine together and feel our tiny place in the universe as both a spec of cosmic existence and one with colossal meaning to each other. She left us feeling inspired to meet some intergalactic neighbors one day, and to recall the importance of our own human neighbors at home too. She was fantastic!”
— David Kuhn, The Nantucket Project
