After research positions at the Heidelberg-Königsstuhl State Observatory and University of Toronto, he received his habilitation at the University of Bonn in 1994.

Lesch is renowned for making complex scientific concepts accessible to the public. His research interests span theoretical astrophysics, cosmology, gravitational waves, and the philosophical implications of scientific discoveries. He has authored numerous books exploring the relationship between science, philosophy, and everyday life, focusing particularly on how cosmic phenomena connect to human existence.

His television career began in 1998 with 'Alpha Centauri' and 'The Physics of Albert Einstein' on BR-alpha. Since September 2008, he has presented ZDF's science magazine, which evolved from 'Abenteuer Forschung' to 'Leschs Kosmos' in 2014, and most recently to 'Terra X Harald Lesch' in 2024. In February 2016, he launched the YouTube channel 'Terra X Lesch & Co,' further expanding his science communication efforts.
