Noche de Estrellas

Welcome back, and welcome to another Noche de Estrellas; our bilingual public outreach night where we have science talks, planetarium shows, and roof-top telescope observing all in both Spanish and English.  This coming week, Cesar Laguna, a staff scientist from Lawrence Livermore National Labs, will be discussing his work on Adaptive Optics.  The planetarium shows will be given by Daniela Flores (Spanish) and Orlando Mayen (English), assisted by Gabriel Zarazua and Rebecca Gore.  Come join the fun and tell your friends and family!

Speaker: Cesar Laguna - Staff Scientist, Lawrence Livermore National Laboratory

"And Just Like That, It Was Gone"

If you look up at the night sky and spot a star, chances are you’ll see it twinkle. However, if you were an astronaut on the International Space Station (ISS) and looked at the same star there is no twinkle. This twinkle is a byproduct of atmospheric turbulence which is one of the biggest challenges for ground-based telescopes. For ground-based telescopes to obtain good and precise images they need to see through that atmospheric turbulence, they need to remove that twinkle. In this talk I will explain what atmospheric turbulence is and how we compensate for it using Adaptive Optics technologies.

"Y así, desapareció"

Si miras hacia arriba, hacia el cielo de la noche, y encuentras una estrella, probablemente vas a verla centellear. Pero, si eres un astronauta en la Estación Espacial Internacional (ISS) y miras a la misma estrella, no se ve centelleando. El centelleo es un efecto de turbulencia de la atmósfera, lo cual es uno de los problemas más grandes para los telescopios ubicados en la tierra. Para que los telescopios en la tierra que necesitan ver a través de esta atmósfera turbulenta, pero necesitan obtener imágenes buenas y precisas, primero hay que quitar ese centelleo. En esta plática, voy a explicar que es la turbulencia atmosférica y cómo la quitamos con tecnología de Ópticas Adaptativas.

El evento se impartirá en español e ingles
