Our fourth lecture of the semester, celebrating the 90th birthday of Carl Sagan. Presented by Professor Shami Chatterjee of the Department of Astronomy. He will be presenting a quick tour of SETI, the quest for planets beyond our solar system, and the prospects for finding life and intelligence beyond the Earth with new telescopes and surveys.

Our third lecture of the semester, celebrating the 102nd anniversary of the Irving Porter Church Memorial Refractor Telescope. Presented by Bart Fried, founder of the Antique Telescope Society. He will be discussing the history of the telescope, and the many important people overlooked in the story.

The Cornell Astronomical Society's second lecture of the semester, presented by Professor Dong Lai of the Cornell Department of Astronomy. He will be discussing compact objects (white dwarfs, neutron stars and black holes), how we study them, and what they teach us.

The Cornell Astronomical Society's first lecture of the semester, presented by PhD student Francisco Martin Blanco of the Cornell Department of Astronomy. He discusses the fascinating ways binary systems of neutron stars and black holes offer us a new window into the universe through their gravitational waves!

On April 8th, 2024, the Cornell Astronomical Society charted 8 buses for 400 students to witness eclipse totality! Thank you to the Rochester Museum and Science Center for an unforgettable event!

In our third lecture of the semester, Maura Lally discusses primary exoplanet detection methods, including transits, radial velocities, and direct detections. She will go into more detail about transiting exoplanets and what we can learn about their atmospheres.

Our fourth lecture of the semester, presented by Professor Phil Nicholson. He will discuss the basics of lunar and solar eclipses, how and why they are governed by the ancient "Saros cycle,” the circumstances of April 8’s eclipse, and ways in which eclipses have uncovered solar physics and the history of the Earth-Moon system. There is no audio from about 15 minutes into the lecture to 30 minut...

Every year on March 14th (3.14), mathematicians, scientists, and STEM aficionados around the world take the time to celebrate the International Day of Mathematics, better known as Pi Day, and we at Fuertes are no different. This year, we marked the occasion with an informational presentation led by our own Dylan Jackaway '24, munched on some cranberry apple pie, and listened to several CAS memb...

The Irving Porter Church 12-inch refracting telescope in Fuertes Observatory has an objective lens designed, ground, and polished by the Brashear Company of Pittsburgh in 1920. Its original glass disks came as a gift from Yerkes Observatory in Wisconsin. Based on an assumption that its two lens elements are made of the same glasses that are in the 40-inch Yerkes refractor, a provisional study h...

Today, evidence of life can be seen all over the Earth, from the land and oceans to the atmosphere. These observations define what we look for when searching for life on other planets. But what about ancient life on Earth? Would the earlier life that roamed the Earth during the past 500 million years (from sponges to the first trees to dinosaurs) have been detectable to aliens from faraway exop...

The Cornell Astronomical Society's first lecture of the semester, presented by Professor James Cordes of the Cornell Department of Astronomy. The Voyager Spacecraft, launched in 1977, famously completed a grand tour of the planets of the solar system. About ten years ago, they left the solar system and are still sending back data. Professor Cordes will discuss this data, what we're learning fro...

On April 8th, 2024, a total solar eclipse will sweep across America. Here's some important safety information to view the last eclipse to cross the country until 2045! Thank you to Valerio Poggiali for his New York eclipse travel poster!

Cornell Astronomical Society President Gillis Lowry gives a lighthearted overview of Carl Sagan's life and legacy! There were technical difficulties throughout this talk, which causes a few slight jumpcuts during the recording. Apologizes for this. Thanks for sticking through-and thank you all for keeping Carl Sagan's legacy alive.

The Cornell Astronomical Society's third lecture of the semester, presented by Dr. Ligia Coelho of the Cornell Department of Astronomy. She discusses how biopigments are an important part of life on Earth and how spectroscopy involving these biopigments can be used to find extraterrestrial life among the cosmos.
