A Stable H2O Atmosphere on Europa’s Trailing Hemisphere From HST Images
Geophysical Research Letters, 2021 Previous studies of the global intensities of the oxygen emissions at 1,356 Å and 1,304 Å revealed molecular oxygen (O2) in Europa's atmosphere. Here we investigate the relative changes of the two oxygen emissions when Europa emerges from eclipse as well

PHANGS–JWST First Results: A Combined HST and JWST Analysis of the Nuclear Star Cluster in NGC 628
The Astrophysical Journal Letters, 2023 We combine archival Hubble Space Telescope and new James Webb Space Telescope imaging data covering the ultraviolet to mid-infrared regime to morphologically analyze the nuclear star cluster (NSC) of NGC 628, a grand-design spiral galaxy.

A 1.3% Distance to M33 from Hubble Space Telescope Cepheid Photometry
The Astrophysical Journal, 2023 We present a low-dispersion period–luminosity relation (PL) based on 154 Cepheids in Messier 33 (M33) with Hubble Space Telescope (HST) photometry from the PHATTER survey.

Attitude Control and Parameter Optimization: A Study on Hubble Space Telescope
Measurement Science Review, 2023 In this work, we build a satellite attitude Proportional-Integral-Derivative (PID) controlled system by using the Hubble Space Telescope (HST) parameters as a reference and tune its controller parameters using various tuning methods.

Expectations for Astrometry with the Hubble Space Telescope [PDF]
Symposium - International Astronomical Union, 1990 The Hubble Space Telescope, a large optical instrument having an aperture of 2.4 meters and a length of 8.8 meters has been developed by the U.S. National Aeronautics and Space Administration in cooperation with the European Space Agency. The Space Shuttle will be used to place the telescope in orbit.
