New observations of the extended hydrogen exosphere of the extrasolar planet HD209458b (2008)
Ehrenreich, David, Etangs, Alain Lecavelier Des, Hébrard, Guillaume, Désert, Jean-Michel, Vidal-Madjar, Alfred, McConnell, John C., ...
Atomic hydrogen escaping from the planet HD209458b provides the largest observational signature ever detected for an extrasolar planet atmosphere. However, the Space Telescope Imaging Spectrograph...

Water vapour in the atmosphere of a transiting extrasolar planet (2007)
Tinetti, Giovanna, Vidal-Madjar, Alfred, Liang, Mao-Chang, Beaulieu, Jean-Philippe, Yung, Yuk, Carey, Sean, ...
Water is predicted to be among, if not the most abundant molecular species after hydrogen in the atmospheres of close-in extrasolar giant planets (hot-Jupiters) Several attempts have been made to...
Detection of the Tip of Red Giant Branc in NGC 5128 (2004)
Soria, Roberto, Mould, Jeremy R., Watson, Alan M., Gallagher, John S. III, Ballester, Gilda E., Burrows, Christopher J., ...
We present a color-magnitude diagram of more than 10,000 stars in the halo of galaxy NGC 5128 (Centaurus A), based on WFPC2 images through the V and I filters. The position of the red-giant branch...
Stellar Populations at the Center of IC 1613 (1999)
Cole, Andrew A., Tolstoy, Eline, Gallagher, John S., Hoessel, John G., Mould, Jeremy R., Holtzman, Jon A., ...
We have observed the center of the Local Group dwarf irregular galaxy IC 1613 with WFPC2 aboard the Hubble Space Telescope in the F439W, F555W, and F814W filters. We find a dominant old stellar...
WFPC2 Observations of Compact Star Cluster Nuclei in Low Luminosity Spiral Galaxies (1999)
Matthews, Lynn D., Gallagher, John S., Krist, John E., Watson, Alan M., Burrows, Christopher J., ...
We have used the Wide Field Planetary Camera 2 aboard the Hubble Space Telescope to image the compact star cluster nuclei of the nearby, late-type, low-luminosity spiral galaxies NGC 4395, NGC 4242,...
HST Far-Ultraviolet Imaging of Jupiter During the Impacts of Comet Shoemaker-Levy 9 (1995)
Clarke, John T, Prange, Renee, Ballester, Gilda E, Trauger, John, Evans, Robin, Rego, Daniel, ...
Hubble Space Telescope far-ultraviolet images of Jupiter during the Shoemaker-Levy 9 impacts show the impact regions darkening over the 2 to 3 hours after the impact, becoming darker and more...
Detection of the SO2 Atmosphere on Io with the Hubble Space Telescope (1994)
Ballester, Gilda E., Mcgrath, M. A., Strobel, D. F., Zhu, Xun, Feldman, Paul D., Moos, H. W.
Observations of the trailing hemisphere of Io made with the Faint Object Spectrograph of the Hubble Space Telescope in March 1992 have resulted in the first detection of atmospheric SO2 absorption...
Latitudinal Temperature Variations of Jovian H+3 (1994)
Ballester, Gilda E., Miller, Steven, Tennyson, Jonathan, Trafton, Laurence M., Geballe, Thomas R.
A spectral image of Jupiter centred on 3.45 [mu]m, taken on the night of April 2, 1992, using cooled grating spectrometer CGS4 on the United Kingdom Infrared Telescope, shows that features due to the...
