A few months ago, a collaboration called the Event Horizon Telescope presented the first direct image of a black hole; or more specifically, of the radiation created by accelerated particles at its event horizon. The EHT is a Very Large Baseline Interferometer, in which radio telescopes all over the world are computationally connected to obtain resolutions that are not possible with one telescope. In the episode I chat with Heino Falcke, the chair of the EHT science committee, about the science, the telescope, what it took to get it going, and image reconstruction.
On October 20, the BepiColombo started its flight to Mercury on an Ariane 5 from Kourou. I was at the launch press event at ESOC in Darmstadt to follow the launch and to record a couple of interviews. The episode consists of three major parts. The first part is an interview with Pablo Munoz about mission analysis and flight dynamics. The second part looks at the science with Joe Zender, Roberto Peron, Ajako Matsuoka and Joana Oliveira. And part three are multiple short takes with Paolo Ferri, Andreas Rudolph and Fabian Luedicke recorded in the middle of the night at ESOC.
SOFIA is an airborne observatory, a Boeing 747SP modified to carry a 2.7m infrared telescope in the back of the fuselage. In late October 2015, I had the opportunity to fly on SOFIA during science missions 248 and 249. This episode captures these two flights. The episode is a mix between interviews with scientists and aircrew, recordings from the intercom system and some narration by me. The list of guests can be seen on the episode page – it is too long for the abstract.
SOFIA is an airborne observatory, a Boeing 747SP modified to carry a 2.7m infrared telescope in the back of the fuselage. In the context of the preparation for my SOFIA flights, I visited the DSI in Stuttgart several times during this summer to record interviews with various DSI people about SOFIA. This episode covers these interviews, plus a recording of the visit of the instrument labs in Palmdale. The guests and topics are Alfred Krabbe, Head of the DSI, on the history and some of the science; Thomas Keilig, CEO of DSI, on the airplane and the modifications; Christian Fischer, Project Engineer of FIFI-LS, on the instrument and some of the science; Dörte Mehlert, Education and Public Outreach, on education and the flying teachers programme; and Zaheer Ali, head of the science and mission operations laboratory, on that lab.
In this episode we talk with Jochen Liske from the European Southern Observatory about the E-ELT Telescope for which construction is about to start. We discuss the engineering challenges of building a 40m mirror and the associated telescope, as well as the science that is planned to be addressed with the E-ELT once it is finished. We also discuss a number of issues around optical astronomy in general that were not covered in our episode about the LBT.
Joe Liske is also the host of both the HUBBLEcast and the ESOCast, two video podcasts about astronomy you may want to check out.
