[2] Hörst moved to the University of Colorado Boulder as a National Science Foundation Astronomy and Astrophysics Postdoctoral Fellow in 2011.
[9] In 2014, Hörst joined Johns Hopkins University[10] as an assistant professor where she specializes in the atmospheric chemistry of planets and their moons.
[11] In March 2018 Hörst's group demonstrated that they could simulate the atmosphere of alien worlds inside the laboratory, allowing them to analyse the composition of their haze.
[12] The study will aid in the analysis of data collected by the James Webb Space Telescope, which NASA expect to launch in 2021.
[14] Hörst won the American Astronomical Society (AAS), Laboratory Astrophysics Division (LAD) Early Career Award for 2020.
