In his upcoming Watson Lecture (March 10, 2021, 5 pm PT), Ken Farley, W. M. Keck Foundation Professor of Geochemistry at Caltech, and Mars 2020 Project Scientist for NASA/JPL, will describe how the Perseverance rover will be utilized to investigate rocks deposited billions of years ago at the bottom of a large lake (long since disappeared) in this search.
He will also look at how the rocks carefully collected by Perseverance during these explorations will provide the cargo for the first-ever effort to bring samples back to Earth from another planet.
This event will be live-streamed. RSVP and real-time attendance required to participate in audience Q&A session at the conclusion.
The two brown dwarfs, weighing about 38 and 34 times the mass of Jupiter, whip around each other every 12 days, and together orbit the M-dwarf star every 250 years.

In experiments in the John W. Lucas Wind Tunnel at Caltech, the team used the large cylinder shown here to create turbulence under high wind speeds and then studied FALCON’s response using the airfoil wing system outfitted with nine sensors and a load cell to measure lift. This slow-mo video, taken with smoke for visualization purposes, was obtained in a different wind tunnel at significantly lower flow speed than the actual experiments.

About the Series
The 2022–2023 season marks the centennial of The Earnest C. Watson Lecture Series, which has brought Caltech's most innovative scientific research to the public since the Friday Evening Demonstrations premiered in October of 1922. The series is named for Earnest C. Watson, a professor of physics at Caltech from 1919 until 1959. The Watson Lectures are geared toward a general audience, as part of the Institute's ongoing commitment to benefiting the local community through education and outreach. All Watson lectures are free and open to the public.
Many past Watson Lectures are available on YouTube.
For more information, please contact The Caltech Ticket Office by email at events@caltech.edu.
This year's program, hosted by Vice President for Student Affairs Kevin M. Gilmartin, included greetings from President Thomas F. Rosenbaum as well as students Sophie Elam and Liam O'Brien. The program also included a panel discussion with faculty members Dr. Jonas Peters, Dr. John Dabiri, Dr. Azita Emami, Dr. Dianne Newman and Dr. Mark Simons.

The bipolar jets drill their way through the surrounding intergalactic medium. Where the ends of the jets hit this medium, a hotspot forms, surrounded by a shock wave. The core of the jet system is the host galaxy containing the supermassive black hole. The backflow consists of material from the hotspot that has decelerated and flowed back toward the host galaxy.

Prior to Porphyrion's discovery, the largest confirmed jet system was Alcyoneus, also named after a giant in Greek mythology. Alcyoneus, which was discovered in 2022 by the same team that found Porphyrion, spans the equivalent of around 100 Milky Ways. For comparison, the well-known Centaurus A jets, the closest major jet system to Earth, spans 10 Milky Ways.
The latest finding suggests that these giant jet systems may have had a larger influence on the formation of galaxies in the young universe than previously believed. Porphyrion existed during an early epoch when the wispy filaments that connect and feed galaxies, known as the cosmic web, were closer together than they are now. That means enormous jets like Porphyrion reached across a greater portion of the cosmic web compared to jets in the local universe.

The robot was programmed to run repeated trials of various stroke mechanics which were then evaluated through machine learning. Eventually the robot, like an injured fish or insect, was able to achieve a successful alternative form of propulsion with its damaged flapper.

Throughout her life, Shelley has played important roles in both biology research and the development of the LGBTQ+ STEM community. She will give us a short history of her career and how it relates to the founding of NOGLSTP ( now Out to Innovate), taking pride in how far scientists and technical professionals have come since the early 1980s. We will also look at where the LGBTQ+ STEM community currently stands and how we can all play a part in helping the community.

Several systems like this one, in which the neutron stars are widely separated from their solar-type companions, have been found using data from the European Space Agency's Gaia mission. The orbital periods of these systems range between six months and three years. In this animation, we are positioned near the path of the compact neutron star as it whizzes past its companion in the distance.

The new computer simulation upends ideas about such disks that astronomers have held since the 1970s and paves the way for new discoveries about how black holes and galaxies grow and evolve.
The telescope itself had previously been disassembled and brought down the mountain.

w/remarks from S. Low
In this video, shot in 2017, Dr. Stone describes his career at Caltech and JPL, and the moment Voyager discovered active volcanoes on Jupiter's moon, Io.
"Usually it's the things that we don't anticipate which turn out to be the most important, it's just that we didn't know they were out there," Stone says.
As he prepares for his 50th consecutive Caltech commencement, Dr. Deutsch recalls the most memorable ceremonies, and traces a life in music and in mathematics at JPL, where he recently retired after a 42-year career.
