Ask yourself—what’s going to stop the government from deporting you to a prison in El Salvador? How would you prove it’s an error if you don’t have due process? If it can happen to anyone, it can happen to you. The people get it. Either everyone has due process—or nobody does.

Do you like pub trivia? How much do you know about astronomy? Take our astronomy-themed pub trivia from last month's Astronomy on Tap and test yourself. The linked video reveals the answers and explanations. Feel free to share your score below! youtube.com/watch?v=4KD8qw…

Galaxies are collections of gas, stars, and dark matter held together by gravity. But how do galaxies, like our own Milky Way, change over their lives? Join us for a 30-minute lecture about galaxies followed by guided stargazing with telescopes: outreach.astro.caltech.edu

How can exoplanet atmospheres teach us how planets form? Dr. Aurora Kesseli explains at our Astronomy on Tap earlier this week. Her presentation is now up on YouTube here: youtu.be/rhrON66wQSE

Come join us for a night of stargazing in Altadena!

Come take a tour through Astronomy on Tap! This was filmed during the intermission period at last week's Astronomy on Tap event, featuring music by Jason Achilles and Forrest Mitchell! outreach.astro.caltech.edu/aot

Join us in one week for our Altadena Stargazing Night at Gwinn Park! We were out there two nights ago and took these images, so you should expect that you'll get to see these beauties and more. More information on our website including directions: outreach.astro.caltech.edu

On May 25, we'll help host the Space Ride, a bike ride to 4 major astronomy sites in Pasadena (Caltech, Carnegie, NASA JPL, and Planetary Society). Each stop will have a short presentation about its role in astronomy, and science done there. More info: eventbrite.com/e/space-ride-t…

Interested in learning about galaxies? We had a Stargazing Lecture last week featuring Evan Nunez discussing the physics of galaxies. His 30-minute presentation is now up on our YouTube channel: youtube.com/watch?v=aEKfPU…

Space weather is the material and radiation emitted by our Sun, including solar flares and solar wind. How can space weather affect us on the Earth and astronauts in orbit. Join our next Stargazing Lecture to find out. Telescopes too! outreach.astro.caltech.edu

Eager to learn about how gravitational waves can "see" black holes when they merge together across the universe? Watch a short presentation from Dr. Gabriele Vajente, the Deputy Head Engineer at LIGO Laboratories: youtube.com/watch?v=3okciv…

What happens when two black holes collide? How do scientists use computer simulations to model black holes? Join us at our next Astronomy on Tap on June 23rd, featuring science talks, pub trivia, telescopes, and live music! outreach.astro.caltech.edu/aot

Last weekend, we helped host the first "Space Ride" a free group bike ride to highlight Pasadena's unique role in astronomy and space discoveries! We had 55 riders join us, cycling between Caltech, NASA JPL, The Planetary Society, and Carnegie Observatories over a few hours.

What is dark matter and how can we find it? Watch our recent Astronomy on Tap talk by Dr. Ana Bonaca from the Carnegie Observatories, who discusses her research to track down this elusive dark matter. Her presentation is now on our YouTube channel: youtube.com/watch?v=1cekoy…

How do scientists simulate black holes on supercomputers? Our Astronomy on Tap earlier this week featured a presentation by Dr. Sarah Habib all about it! Check out the link below to watch it: youtu.be/FFZ-Dss7Xbg

Why do scientists believe that dark matter actually exists despite not having found it yet? How do we identify stars that are about to die and what happens next? Join us Monday, July 14th at 7:30PM for our next Astronomy on Tap. outreach.astro.caltech.edu

How did our Solar System form, and how does it compare with other planetary systems around our galaxy? Last Friday, we hosted Adolfo Carvalho to discuss this topic at our Stargazing Lecture. His wonderful presentation is now up on our YouTube channel: youtube.com/watch?v=A0pFhj…

¡Esta noche!

Last weekend, we helped out at the Sequoia Dark Sky Festival in Sequoia National Park. Our group gave some public science presentations, operated telescopes at the star party, and hosted an Astrophysicists Q&A Panel to attendees at the festival. We hope to be back next year.

There is a proposed rule to allow the government to build roads through much of our national forest lands. TODAY IS THE FINAL DAY for us to comment on this government proposal and to oppose it. The Sierra Club provides an easy form to achieve this: act.sierraclub.org/actions/Nation…
