Olayinka Fagbemiro is with the Nigerian space agency and also heads Astronomers Without Borders in her nation. Emily Lakdawalla tells us about four exciting planetary science missions that are currently competing for selection by NASA. Bruce Betts tells us about the search for 100 earths as he also asks us to find a citizen of Middle Earth in space.

The Los Angeles Astronomical Society (LAAS) is one of the oldest and largest amateur astronomy clubs in the United States, and this year, it’s turning 100. To mark the occasion, the LAAS threw a centennial star party on the lawn of Griffith Observatory, featuring 100 telescopes, a dedication ceremony, and a community of passionate skywatchers who showed up rain and all.

In this episode, we sit down with Laura-May Abron, vice president of the Los Angeles Astronomical Society and chair of its Centennial Committee, to discuss what it took to put together the event. We drop into the centennial dedication ceremony to hear from LAAS President Keith Armstrong and Griffith Observatory Director Ed Krupp. We also spend time with some of the remarkable members who make this community what it is, including LAAS historian Louis Chilton, who has been a member for over 60 years, research scientist and LAAS member Bryce Bolin, self-taught optician and telescope builder Jeff Schroeder, and Geo Somoza, volunteer at The Planetary Society and one of the people who has dedicated his life to showing others the sky. Plus, Bruce Betts joins us for What's Up and a look at what you can spot in the night sky in June.

The Los Angeles Astronomical Society is one of the oldest and largest amateur astronomy clubs in the United States, and this year it’s turning one hundred. We were there at Griffith Observatory for the centennial celebration to find out what keeps a community of skywatchers going for a century.

NASA's Curiosity rover has been exploring Mars' Gale Crater for over a decade. A new analysis of samples collected there reveals something remarkable: more than 20 different organic molecules preserved in ancient rock, including the first detection of a nitrogen-bearing heterocycle on Mars, a type of molecule that's a precursor to compounds essential for life as we know it.

While these molecules aren't evidence of life, they tell us that the chemical building blocks for life were present in ancient Martian environments. In this episode, we talk with Amy Williams, an astrobiologist and associate professor at the University of Florida, about what this discovery means for our understanding of Mars' habitability. Then, Planetary Society Chief Scientist Bruce Betts joins us for What's Up, where we compare the results to samples collected from asteroid Bennu.

Amy Williams, astrobiologist and associate professor at the University of Florida, discusses a landmark experiment that revealed more than 20 organic molecules preserved in ancient Martian rock. We explore what this chemical discovery tells us about Mars' ancient habitability.

Author, poet, and science communicator Diane Ackerman is our guest. Her wonderful collection of poems, with one devoted to each of the worlds in our Solar System, was first published in 1976. Carl Sagan said she had produced, “...a stunning book of poetry in The Planets. The work is scientifically accurate and even a convenient introduction to modern ideas on the planets, but much more important, it is spectacularly good poetry, clear, lyrical, and soaring. . . One of the triumphs of Ackerman’s pastoral is the demonstration of how closely compatible planetary exploration and poetry, science and art really are.” “The Planets” is now available in a brand new edition, and is as sublime, entertaining, and enlightening as it was half a century ago.
