He is a project scientist at the Event Horizon Telescope and played an important role in the creation of the first image of a black hole. In this episode we talk about what it means to be an astronomer on Hawaiʻi, both in terms of daily operations as well as concrete projects such as imaging a black hole. We also discuss the controversial impact that the telescopes have had on Maunakea and how the naming of the black hole at the centre of the galaxy M87 with a phrase from the Hawaiian language paid tribute to the Hawaiian legacy.


The episode was recorded as part of a research trip to Hawai'i that I made for a book about black holes. The book is now published as Facing Infinity: Black holes and our place on Earth (Atlantic Books, UK and The Experiment, US/Canada). It is available to order from facinginfinity.com.

My guest for this episode is Luis Calçada, who is a data visualisation artist at the European Southern Observatory, also known as ESO. This organisation builds and runs some of the most powerful telescopes in the world, and it’s Luis job to make sure that the data collected by these telescopes is presented in an visually appealing and educational way to the general public. We discuss how astronomical images are created, what an artistic illustration is and what the role astronomical visualisations play for our understand of the universe.

In this episode, I talk with Ann C. Thresher from Stanford University about the relationship between astronomy and colonialism, and the ethical dimensions of telescope sitings. Thresher is a leader of the Responsible siting group within the Next Generation Event Horizon Telescope, and is actively involved in reaching out to local communities in the early stages of new telescope projects.

But what has happened since then? What have the gravitational wave hunters learned about not only black holes, but also neutron stars and even the expansion of the universe? In this episode, associate professor Salvatore Vitale from MIT and the LIGO collaboration will answer these questions, and also describe what we can expect from the future of gravitational wave astronomy.
