Astronomy enthusiasts,
We have a couple of astronomy outreach events over the next month (including tonight!). As always, these events are free and open to all, no reservations necessary. For more information about these events, including directions, please visit our Caltech Astro Outreach website. Notably, recordings from past lectures and presentations are featured on our YouTube channel.
Friday, August 15 @ 7:30PM
Noche de las Estrellas
Join us for a Stargazing Lecture on the topic of black holes and gravitational waves entirely in Spanish, featuring a public lecture and guided stargazing with telescopes.
Únase a nosotros para una conferencia de observación de estrellas sobre el tema de los agujeros negros y las ondas gravitacionales completamente en español, que incluirá una conferencia pública y observación de estrellas guiada con telescopios.
Los agujeros negros son objetos astronómicos con una gravedad tan intensa que ni siquiera la luz puede escapar de ellos, y, por lo tanto, son invisibles. ¿Cómo es posible detectarlos y estudiarlos, entonces? Una forma es "mirar" los efectos que su gravedad produce sobre otros objetos luminosos, como gas o estrellas, y otra es "escuchar" las ondas gravitacionales que dos agujeros negros emiten al orbitar y colisionar entre sí. Las ondas gravitacionales son pequeñísimas deformaciones del espacio-tiempo, posibles de detectar desde hace una década, que nos permiten hacer astronomía sin la necesidad de observar luz. En esta charla voy a discutir qué son los agujeros negros y las ondas gravitacionales, cómo es posible detectarlas usando los instrumentos más sensibles del mundo, y qué nos han permitido aprender sobre cómo se forman y comportan estos fascinantes objetos.

Cosmic Fireworks: How Astronomers Explore the Changing Sky - Sam Rose
Cahill Center for Astrophysics, Caltech Campus
YouTube Livestream Link
What causes the cosmic flashes that we see in the sky? What will the Rubin Observatory observe when it begins operation in a few months? Join us for a 30-minute lecture about cosmic fireworks, followed by a panel Q&A consisting of several astrophysicists to answer your questions about astronomy and space science. Event will be held both in-person as well as live-streamed on YouTube Live.
"The Universe evolves over the course of billions of years—a timescale almost incomprehensible to humans. But there are some things in the night sky that change much faster. Spectacular explosions of massive stars dying, pulsing stars, and comets and asteroids drifting through our Solar System are all examples of changes in the sky that happen over the course of weeks, months, or years. These events which cause new sources of light to appear and disappear in the sky are called “astronomical transients.” In this talk, we will explore the history of astronomical transients: including observations of an exploding star by Chinese astronomers in 1054 CE, the search for comets over the centuries, and the first large-scale surveys of the sky using the Mt. Wilson and Palomar observatories. We will also cover the next-generation efforts to detect these events using Caltech's very own Zwicky Transient Facility (ZTF) and the brand new Vera Rubin Observatory, which will reveal millions of new asteroids and supernovae across the sky in the coming years."
