Latest Paul Kalas Stories
According to newly released images from the Hubble Space Telescope, a vast debris belt circling around a nearby star is wider than scientists believe, and the unusual orbit of a planet traveling around that star could be to blame.
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.
These two bright debris disks of ice and dust appear to be the equivalent of our own solar system's Kuiper Belt, a ring of icy rocks outside the orbit of Neptune and the source of short-period comets.
Dusty disk around Fomalhaut makes ideal laboratory for studying planet formation.
The Hubble Space Telescope's most detailed visible-light image ever taken of a narrow, dusty ring around the nearby star Fomalhaut (HD 216956), offers the strongest evidence yet that an unruly and unseen planet may be gravitationally tugging on the ring. The center of the ring is a whopping 1.4 billion miles away from the star.
