November 14, 2008 - National Post, Canada
For the first time, Canadian and American astronomers have obtained photographic evidence of planets that orbit distant stars.
...
The Hubble, Keck and Gemini telescopes that produced these photos are not new, but Mr. Marois said a change in the searching method, rather than new technology, made the breakthrough.

Pictured: First images of planets outside our solar system as new era in astronomy dawns
November 14, 2008 - Daily Mail, UK
Scientists have taken the first snapshots of another solar system, ushering in a new era in astronomy.
The infrared images show a family of three giant worlds orbiting a young hot star in the constellation of Pegasus, 130 light years from Earth. A light year is the distance light travels in a year - 6trillion miles.
In another development also reported in Science, Nasa's Hubble Space Telescope photographed a single Jupiter-sized planet called Fomalhaut b orbiting a close neighbour of the Sun just 25 light years away.
...
Christian Marois of the Herzberg Institute for Astrophysics and his team used the Keck and Gemini telescopes in Hawaii to find the three planets near the star called HR 8799, which is just visible to the naked eye.

New planets swim into our ken
November 14, 2008 - Sydney Morning Herald
ASTRONOMERS have parted the curtains of space to take the first photographs of planets that orbit stars other than our sun.
...
Two teams took part in the milestone. The first, led by Berkeley researchers, used the Hubble space telescope to take a picture of a giant planet orbiting Fomalhaut, a star that is 25 light years from Earth.
...
The other effort relied on the giant Keck and Gemini telescopes in Hawaii to image three planets surrounding the young star HR8799, 130 light years away.

Astronomers Discover New Exoplanets
November 14, 2008 - NPR
Astronomers are getting their first real glimpses of planets in orbit around distant stars.
...
Meanwhile, an international team of astronomers say they've seen not just a single planet, but a small solar system around a star called HR 8799 (The name might sound like a personnel form, because astronomers sometimes can't decide whether to be scientific or romantic.)

First 'bona fide' direct images of exoplanets
November 13, 2008 - PhysicsWorld
Two teams comprising researchers from Canada, the US and the UK have taken what appear to be the first “bona fide” direct images of planets orbiting stars outside the Solar System, an achievement that has long been considered vital in the search for planets like our own.
Christian Marois of the Herzberg Institute of Astrophysics in Canada and colleagues have used the ground-based Gemini telescopes in Hawaii and Chile, and the Keck telescopes, also in Hawaii, to take infrared images of three giant planets that they claim are orbiting a star about 130 light-years away in the Pegasus constellation (Science Express 10.1126/science.1166585).

First images captured of alien solar system
November 13, 2008 - NewScientist
Astronomers have snapped what they say is the best photographic evidence yet of planets orbiting other stars. Two new planetary systems have been imaged in the Milky Way; one offers the first glimpse of a system with multiple planets.
...
Christian Marois of the Herzberg Institute of Astrophysics in Victoria, Canada, and colleagues found a system with three planets in an ongoing survey of 80 young stars surrounded by relatively large amounts of dust.
...
The planets, which formed some 60 million years ago, are still glowing with heat from their contraction. Their march across the sky with the star, as well as their counter-clockwise orbit around it, were measured in near-infrared images taken with the Keck and Gemini North telescopes in Hawaii.
