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:

It 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.  This podcast is the audio version of a Future in Space Hangout sponsored by the American Astronautical Society.

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!

This 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.
