The sunshade allows observations of planets outside the solar system

Like a hand covered in front of the eye to reduce the glare of the Sun, a giant sunshade with a flower-like shape extends its wings in space to allow direct observation of extrasolar planets through a glass Space prospect is being developed by US space researchers.

The sunshade model imagined by astronomer Webster Cash Until now, extrasolar planets have only been detected indirectly through the disturbances they cause when orbiting their star.

American astronomer Webster Cash of Boulder University in Colorado has found a way to reduce the sun's light so that it can observe the weak light of a planet that has life outside the solar system. He imagined a shield with a width of 30 to 50 meters spread wide in space and connected to a probe. About 40,000km from the telescope, while the telescope is also on orbit 1.5 million km away from Earth, this sun shield will create a dark area that allows the planets to be seen.

The sun visor looks like a sunflower: according to Cash, this is the best way to deflect light without making some rays obscure the planets.

The researcher presented this project to NASA so that it could work with the future James Space Web Space Telescope expected to launch in 2013.

The US Space Agency currently encourages less-expensive destiny that allows the discovery of planets that have life outside the solar system.
