The fifth Annual Yuri’s Night Lecture at Cornell: “Thousands of New Worlds” 7:30pm is a public lecture under the stars (and star gazing) that takes place tonight at Fuertes Observatory (bring a blanket if the weather cooperates). This event celebrates Yuri’s night (see below).

“Thousands of New Worlds” by Dr. Lisa Kaltenegger, Cornell Prof. of Astronomy/Director of the Carl Sagan Institute, April 14, 2017

The detection of exoplanets orbiting other stars has revolutionized our view of our place in the universe. First results suggest that it is teeming with a fascinating diversity of rocky planets including those in the Habitable Zone. The next generation of telescopes will be able to peer into the atmospheres of rocky planets and give us a glimpse into other worlds. Our own planet and its wide range of biota serves as a Rosetta stone for how we could detect habitability and signs of life on exoplanets. For the first time in human history we have developed the technology to detect potential habitable worlds.

Yuri’s Night is a global celebration of humanity’s past, present, and future in space. Yuri’s Night parties and events are held around the world every April in commemoration of Yuri Gagarin becoming the first human to venture into space on April 12, 1961, and the inaugural launch of the first Space Shuttle on April 12, 1981.

Yuri’s Night events combine space-themed partying with education and outreach. These events can range from an all-night mix of techno and technology at a NASA Center, to a movie showing and stargazing at your local college, to a gathering of friends at a bar or barbecue.

In 2011, the 50th anniversary of human spaceflight, over 100,000 people attended 567 officially-recognized events in 75 countries on all 7 continents, while tens of thousands more watched the 12-hour live Yuri’s Night Global Webcast and participated online in the virtual world of Second Life.
