Two years for James Webb, episode 3: Tel Aviv 360 podcast of Tel Aviv University (Hebrew only)
We are marking two years since the launch of the James Webb Space Telescope, undoubtedly one of the most impressive feats of engineering in human history. The telescope, launched at the end of 2021, is located one and a half million kilometers from Earth, equipped with unprecedented resolution and sensitivity that allow it to produce spectacular and detailed space photographs and reveal the universe as we have never seen it. The abilities of James Webb take us on a journey through time to the beginning of the universe. In its first two years, the telescope achieved enormous successes, with its main goals including: studying the way everything was created - including us - investigating the formation and development of the first galaxies and stars, and studying celestial phenomena such as black holes. In addition, Web helps to understand the properties and shapes of celestial bodies, analyze the atmospheres of distant planets, and perhaps even answer the great question of humanity: are we alone in the universe?
We will talk about all these topics, and more, in a four-part series of "Tel Aviv 360", with the participation of leading researchers from the School of Physics and Astronomy at Tel Aviv University. In the third episode, we will talk about Webb's first mission - the study of the early universe and the formation of stars and galaxies - with Professor Renan Barkana, an expert in these fields. During the conversation we will deal with fascinating topics such as young galaxies, newly formed stars, dark matter, black holes, and we will discuss the intriguing question: what came first - the galaxy or the black hole at its center? We will also examine how the James Webb Telescope challenges the accepted cosmological model. In addition, we will also deal with the ground-breaking research of Professor Barkana, in which he tries to observe the universe even earlier than the one that Webb is able to see, using radio waves. You are invited to listen to the special podcast of "Tel Aviv 360" hosted by Dror Foyer.
