This episode covers the discovery (strictly speaking, “strong evidence”) for high-energy (astrophysical) neutrinos. The discovery was announced on 22 November 2013. In this episode we talk with DESY‘s Markus Ackermann about the the evidence for astrophysical neutrinos and why they are important. We also discuss how the the IceCube Neutrino Observatory works, which opened up this new field of astronomy. We conclude with a brief conversation about traveling to, and living at the south pole, where IceCube is located.
This episode covers the moon, and in particular, its creation. We talk to the two scientists who came up with the theory of the moon’s creation that is still prevalent today: Don Davis and Bill Hartmann In the episode we discuss in detail their theory that the moon has been created by an impact event into earth, as well as some of the history of this theory. We also discuss other space related topics such as water on the moon, human vs. robotic space flight, and flights to Mars.
This is the first of two episodes recorded at the Planetary Science Institute in Tucson, Arizona. This episode has two interviews. The first one, with Mark Sykes, the director of PSI, is about the PSI and planetary science in general. The second interview is with Beatrice Mueller about her research area, comets.
This epsiode covers my visit at the Large Binocular Telescope near Tucson, Arizona. The episode is mostly a conversation with the telescope’s director, Richard Green. We talk about optical astronomy in general and the LBT in particular. I also talk to a scientist who is currently observing at the telescope as well as a telescope operator.
This episode is a conversation with JPL‘s Anita Sengupta about Curiosity’s landing on Mars. We first discuss the landing process itself and then focus on various aspects of the landing, in particular, the parachute. Next we discuss the development and test of that parachute. We conclude the episode with a general discussion about Mars Science Lab, Curiosity and space flight in general.
This episode is about the Cassini Mission to Saturn. We talk with Nora Kelly Alonge, a Project Science System Engineer and Science Planning Engineer at NASA Jet Propulsion Laboratory. In the episode we cover the Cassini spacecraft’s structure and sensors (and its lander, Huygens), some of the relevant science, as well as the challenge of coordinating science and engineering requirements on the mission.
This episode is a conversation with Volker Springel about the Millenium Simulation, which at the time was the largest simulation of the growth of cosmic structure, including a detailed model for the formation of galaxies and supermassive black holes. In the episode we talk about the physical/cosmological background, the simulation process and approach as well as some details about the hard- and software.
This episode is a conversation with Dr. Carl Pilcher, the director of the NASA Astrobiology Insititute at NASA Ames Research Center. The conversation comes in two parts. Part one covers the conceptual basics of astrobiology and life: what is life, what are the preconditions for life to exist, how to recognize it, etc. Part two looks at the process of trying to find places in the universe that could host life, primarily astronomical observations and missions to other planets.
This episode is a discussion about radio astronomy and the ALMA observatory with ESO’s Robert Laing, the European instrument scientist for ALMA. The episode has three parts. The first part talks about the science of radio astronomy: current challenges and physical basics. The second part adresses how observing with radio astronomy actually works: the principles behind telescopes and how they are built and operated. Part three then looks at the ALMA observatory specifically, a new, large sub-millimeter radio interferometer currently built in the Atacama Desert in Chile.
