Kristian Birkeland and his terrella experiment

Laboratory astrophysics is a branch of physics which attempts to "simulate celestial bodies in a terrestrial laboratory". Kang et al note that:

"Despite huge differences in time and space scales and other parameters between astronomical phenomena and laboratory environments, the idea of laboratory simulation is based on the fact that both systems are described generally by pure hydrodynamic or magnetohydrodynamic motions; thus, there exist similarities. For example, the plasma universe concept, which suggests that general laws of plasma physics hold from laboratory, magnetospheric, and heliospheric plasmas to interstellar and intergalactic plasmas, gives insight into cosmic plasma [2–4]"[1] [2]

Laboratory tools

A number of laboratory tools are used, including terrellas, pinches, dense plasma focus, electrical discharges, and lasers.[3] The field was pioneered by Kristian Birkeland whose terrellas modelled the aurora, used extensively by Hannes Alfvén, [4], and physicists such as Winston H. Bostick whose laboratory-generated plasmoids resembled galaxies.[5][6][7]
