We report observations of four energetic volcanic eruptions on Io: at Tupan Patera on UT 8 March 2003; Tung Yo Patera on UT 28 May 2004; Sui Jen Patera on UT 30 May 2004; and south of Babbar Patera on UT 31 May 2005. The Tung Yo, Sui Jen and south of Babbar Paterae eruptions are in locations where no activity had been seen before. Our observations ...

The James Webb Space Telescope (JWST) provides the opportunity for ground- breaking observations of asteroids. It covers wavelength regions that are unavailable from the ground and does so with unprecedented sensitivity. The main belt and Trojan asteroids are all observable at some point in the JWST lifetime. We present an overview of the capabilit...

Using the recently installed Gemini Planet Imager (GPI), we have taken the first H-band spectrum of the planetary companion to the nearby young star beta Pictoris. GPI is designed to image and provide low-resolution spectra of Jupiter sized, self-luminous planetary companions around young nearby stars. These observations were taken covering the H-b...

The Gemini Planet Imager (GPI) is a facility extreme-AO high-contrast instrument– optimized solely for study of faint companions–on the Gemini telescope. It combines a high- order MEMS AO system (1493 active actuators), an apodized pupil Lyot coronagraph, a high- accuracy IR post-coronagraph wavefront sensor, and a near-infrared integral field ...

The newly commissioned Gemini Planet Imager (GPI) combines extreme adaptive optics, an advanced coronagraph, precision wavefront control and a lenslet-based integral field spectrograph (IFS) to measure the spectra of young extrasolar giant planets between 0.9-2.5 μm. Each GPI detector image, when in spectral model, consists of~ 37,000 microspectra...
