n ambitious project to seek planets outside the solar system is being spearheaded by UK scientists.

The ground breaking SuperWASP initiative is being launched by a team of astronomers at an observatory in the Canary Islands on Friday.

The programme, which involves a network of cameras around the world, will measure the brightness of 50 million stars every night.

Lens effect reveals distant world

The most distant known planet has been detected orbiting a star some 17,000 light-years away, say astronomers.

It was found because, as seen from the Earth, it passed in front of a more distant star and its gravity amplified the background star's light.

This "gravitational lensing" effect was predicted by Albert Einstein in his General Theory of Relativity.

Nasa says that the way the background star's brightness changed revealed the existence of the planet circling it.

The gravitational field of a foreground star bends and focuses light from a background star, like a lens in a telescope, but only if the foreground and background star are precisely aligned.

Nice find. I remember when they were only looking towards VLAs and space based interferometry to find terrestrial sized planets. Now techniques are being developed with lesser telescopes that may be able to find them. it is only a matter of time before the first extra-solar terrestrial class planet is announced.
