Lightning is one of the most experienced and most severe phenomena on Earth and might be a possible trigger for the creation of life. But how likely was lightning in the early days of Earth (approx. four billion years ago).

The purpose of this master project is to understand which conditions were necessary to incept lightning discharges on Earth in its beginning. Therefore we need to understand the inception and motion of electron avalanches and of streamers, conductive, microscopic plasma channels forming the early stages of macroscopic lightning, in the atmosphere of Early Earth.

The project consists of literature study about the atmospheric composition of Primordial Earth, introduction of electronic collisions in a gas mixture, performing numerical simulations and conclusively post-processing of simulation results. The main goal of the master project is to determine which conditions were necessary to favour the formation of lightning on the primordial Earth.

We at DTU Space, located in Lyngby, study various phenomena related to lightning ranging from the very early microscopic conditions to macroscopic manifestations. Recently, we have started to understand the first stages of extraterrestrial lightning on Titan and which conditions are needed for the inception of lightning.

Technical University of Denmark

For almost two centuries DTU, Technical University of Denmark, has been dedicated to fulfilling the vision of H.C. Ørsted – the father of electromagnetism – who founded the university in 1829 to develop and create value using the natural sciences and the technical sciences to benefit society.


Today, DTU is ranked as one of the foremost technical universities in Europe, continues to set new records in the number of publications, and persistently increases and develops our partnerships with industry, and assignments accomplished by DTU’s public sector consultancy.
