![]() Not only do supernovae serve as the mechanism for the creation of these heavy elements, they also serve as the mechanism for their dispersal. Credit: Penn State Astronomy & Astrophysics The core is a series of nested spherical shells, with each shell fusing a different element from hydrogen to helium, to carbon, through the periodic table to iron. We are insignificant, a tiny transient structure, and if we are lucky, our presence is recorded by other tiny transient structures.Įlements up to iron are formed in stars more massive than our Sun.Īrtist’s illustration of the core of a massive star just prior to a type II supernova explosion. Our bodies are just tiny shapes of matter that exist for a very short time on a tiny insignificant planet, in a very large Universe that has been around for nearly 14 billion years. This matter is in the food that keeps us alive. We are all made up of matter that was once produced in massive stars that exploded. The professor’s astronomical studies have given him a sense of modesty. Housed in three locations in and around Berlin, Germany, the BBAW is the largest non-university humanities research institute in the region. The Berlin-Brandenburg Academy of Sciences and Humanities, abbreviated BBAW, is the official academic society for the natural sciences and humanities for the German states of Berlin and Brandenburg. Since 2009, she has regularly worked as an author and photographer for ZEIT magazine, in the column “What saved me”. She has received a number of awards for her photographic work, for example the Dr Erich Salomon Prize in 2001. She is particularly interested in creating portraits of milieus and people. Her comprehensive work is characterised above all by long-term photographic projects, often complemented by in-depth interviews. Herlinde Koelbl (born 31 October 1939) is a German photographic artist, author and documentary maker. ![]() The photographer, who took the photograph above left, asked the professor to write on his hand an important science question. I hope the Professor Loeb and my readers will forgive any mistakes and let me know what I got wrong. Even though I could stop the video and go back over things there are likely to be mistakes because I haven’t heard things correctly or not understood them. The following are notes from the on-line lecture. If so, we can learn a lot from others out there. We might be a form of life as primitive and common in the cosmos as ants are in a kitchen. Our civilization will mature once we find out who resides on our cosmic street by searching with our best telescopes for unusual electromagnetic flashes, industrial pollution of planetary atmospheres, artificial light or heat, artificial space debris or something completely unexpected. First tentative clues were claimed close to Earth: the weird interstellar object `Oumuamua and the cloud deck of Venus. He had been the longest serving Chair of Harvard’s Department of Astronomy (2011–2020), Founding Director of Harvard’s Black Hole Initiative (since 2016) and Director of the Institute for Theory and Computation (since 2007) within the Harvard-Smithsonian Center for search for extraterrestrial life is one of the most exciting frontiers in Astronomy.
