Meanwhile, a team led by Paul Kalas of the University of California has used a camera onboard the Hubble telescope to image a giant planet that appears to be orbiting Fomalhaut, a bright star that lies about 25 light-years away in the Piscis Austrinus constellation (Science Express10.1126/sci...

In this dissertation we report on the design, development, laboratory testing, and initial on-sky results of MagAO and VisAO, which include the first ground-based image of an exoplanet (beta Pictoris b) with a CCD. We also discuss some of the exciting science planned for this system now...
This false-color composite image traces the motion of the planet Fomalhaut b, a world captured by direct imaging. (Image credit: NASA, ESA, and P. Kalas (University of California, Berkeley and SETI Institute)) The hunt for planets around other stars is gaining speed. NASA's Kepler Space...

Here we use Gaia astrometry combined with 2MASS photometry to model the parallax and proper motion distributions of field stars around exoplanet host stars as a function of candidate magnitude. We develop a likelihood-based method that compares the positions of a candidate at multiple epochs with ...
The article focuses on research published in a 2015 issue of "Science" reporting that astronomers Bruce Macintosh and colleagues used the Gemini Planet Imager at the Gemini South Telescope located in Chile to directly image a planet orbiting the star 51 Eridani and mentions spectroscopic analysis ...
