1 Patti Truant Anderson: Polling and the Surprising Results Around What People Really Think About the Food System 24:55
Text “Do people even want to know about some of these issues? Because I think some of the meat production concerns, it's kind of like people would rather in some cases, I think some people might not really want to know all the nitty gritty. They don't want to know how the sausage is made. That poses an interesting question and challenge about how you communicate about some of these issues, when maybe there's a resistance among a subset of people who don't want to know more.” - Patti Truant Anderson Today’s episode is the final installment in our special four-part series where we take a deep dive into the food system with experts from the Johns Hopkins Center for a Livable Future. Our guest is Patti Truant Anderson, a senior program officer at the Center and a faculty associate in the Department of Health Policy and Management at the Johns Hopkins Bloomberg School of Public Health. Patti’s work focuses on public health risks, environmental challenges tied to food production, and how to communicate these critical issues more effectively. Patti and I explore how polling helps uncover public perceptions around food systems and why the country isn’t as polarized on these issues as we might think. We also talk about the challenge of engaging people who may resist learning about the harsh realities of our food system. This episode is not just about data—it’s about how we can foster a shared understanding and move forward, even in times of deep political division.

HabEx is one of four concept missions being considered for the next generation of space telescopes. HabEx will search for rocky worlds like Earth in orbit around other stars and it will have unique capabilities to detect atmospheres and even the components of those atmospheres. The idea is to look for biosignatures on planets for signs of life!

×Here's the first installment of Countdown to JWST, a podcast that will track the mission up to launch (hopefully) later this year. Let's light this candle!
Was there a first cause? Can there be a event that started everything? What would such an event look like? In this episode Tony and Charlotte discuss the scientific and philosophical understanding of the beginning of the universe and what an effect that does NOT have a cause must look like.
This episode kicks off what I hope will be a weekly posting for the DA Show. My wife Charlotte is a Catholic theologian and philosopher who has taught me much outside of my scientific realm. I have heartily enjoyed our conversations over the years and now I hope to share some of them with you.
Remember all the commotion about the BICEP2 mission back in 2014? Cosmologist had announced the observation of polarized "B-mode" waves that, if connected to the universal cosmic microwave background, would lend credence and observational support to the Inflationary Theory of Cosmology, this period just after the Big Bang when astronomers think the universe expanded exponentially and faster than light. The story made the front page of the New York Times and we were hearing about it everywhere. While I doubt that very many people understood what was being said, clearly something big was happening and so everyone paid attention. Dr. Brian Keating from USCD was a member of the BICEP2 team and talks about that time with me along with other really interesting goings-on in the world of science, including whether having something like the Nobel Prize is hurting science. Brian Keating's Book: "Losing the Nobel Prize: A Story of Cosmology, Ambition and the Peril of Science's Highest Honor" is available on the Deep Astronomy Amazon Page here: https://amzn.to/2JHl7W4…

1:02:27It turns out that NASA and others have been thinking about the inefficiencies of using chemical rockets to go to the Moon, Mars and the Outer Planets. One very attractive solution is Nuclear Thermal Propulsion, a technology that was begun in the 1960's and considered as a viable method of propelling Apollo astronauts to the Moon, but was abandoned in favor of chemical rockets. Fast forward to the twenty first century and we are back thinking about using this promising propulsion to get humans and space probes to the outer solar system quickly.

Let's talk about the potentially hazardous asteroid known as Apophis. In April, 2029 this 320 meter rock will get so close that it will pass under the orbit of geosynchronous satellites! Astronomers held a conference in late April of 2019 to discuss the science that can be done as it passes so close to the Earth.…
In this podcast: an essay on whether the effort that went into making the black hole image in the distant galaxy M87 by the Event Horizon Telescope was worth it; an interview with star mapper Wil Tirion and more!

1:00:47This podcast features science and technology from the Large Millimeter Telescope. Our guests Nat DeNigris and David Sanchez will be on hand to discuss this amazing facility being operated in Mexico. The Large Millimeter Telescope is the world's largest single-aperture telescope in its frequency range, built for observing radio waves in the wave lengths from approximately 0.85 to 4 mm. It has an active surface with a diameter of 50 metres and 1,960 square metres of collecting area.…

1:01:52We've known since Edwin Hubble's time that the universe has been expanding. What we've only recently learned (like, in the past 10 years or so) is that the universe is accelerating as it expands. Measuring this expansion rate has been problematic and while there are at least two different ways to make the measurement, they don't always agree. This episode features Ed Macauley from the University of Portsmouth UK, and a member of the Dark Energy Survey collaboration. He and his team have been using a calibrated version of the 'standard candle' method of determining the rate of universal expansion, also known as the Hubble Constant or H0 to get a better answer that agrees with other measurement techniques. You can read Ed's paper on Arxiv.org here: https://arxiv.org/pdf/1811.02376.pdf…
I'm not convinced that life is everywhere in the cosmos. It is entirely possible, based on what we know today, that we are the only life there is. Anywhere. This episode is a brief discussion of that idea.

Astronomy’s Future Will Be Built: New Capabilities to Assemble in Space the Largest Observatories. Scientific performance of telescopes depend strongly upon the observatory’s aperture, its capability to collect faint light. Eventually, the challenging goals of astronomers will require telescope mirrors larger than can be deployed in space without the capability to assemble them, either with astronauts or with robots, enabled by the decreasing cost of commercial launch vehicles. Join Tony Darnell as he discusses the promise, the challenges, and the capabilities being assessed to assemble the largest future space observatories with Drs. Nicholas Siegler (NASA JPL), Bradley Peterson (OSU/STScI) and Gordon Roesler (Robots in Space LLC). Come hear about a new NASA-chartered study that is looking into this potentially enabling capability. Future in Space Hangouts are endorsed by the American Astronomical Society and the American Astronautical Society.…

1:02:24For decades advocates of the exploration of the Moon have argued that this will make possible subsequent exploration of Mars. But is this really true? Recently several dozen experts critically examined whether astronaut exploration of the Moon could be used to feed forward to a human mission to the martian surface by the end of the 2030s. Their findings may surprise you. Join Tony Darnell and Alberto Conti as they discuss the findings of a recent Moon-to-Mars workshop with Clive Neal (Notre Dame), Steve Mackwell (USRA), and Joseph Cassady (Aeroject Rocketdyne).…
