A picture is worth a thousand words, or so University of California, Berkeley, astronomer Paul Kalas found out when he published a Hubble Space Telescope image of a Jupiter-sized planet orbiting the star Fomalhaut.

NASA's Hubble Space Telescope has taken the first visible-light snapshot of a planet circling another star.

Astronomers using the Hubble Space Telescope and W. M. Keck Observatory have found a lopsided debris disk around a young star known as HD 15115. As seen from Earth, the edge-on disk resembles a needle sticking out from the star.

New observations from NASA's Hubble Space Telescope have begun to fill gaps in the early stages of planet birth.

U.S. astronomers say the Hubble Space Telescope has confirmed what has been long predicted: planets form from debris disks around stars. More than 200 years ago, philosopher Emmanuel Kant first proposed that planets are born from disks of dust and gas that swirl around their home stars.
