Amy's charity Bennett duet

A duet between Tony Bennett and the late Amy Winehouse is being released as a single to benefit a charity established by her father.

The classic pop standard Body and Soul that Winehouse recorded with Bennett in March is one of her last works. She died unexpectedly at age 27 on July 23, after a long battle with alcohol and drugs.

Proceeds from the single, will go to a foundation set up by Amy's dad, Mitch.

The Earth once had two moons, astronomers now think. But the smaller one smashed into the other 4.4 billion years ago in what is being called the "big splat".

The result was our planet was left with a single bulked-up and ever-so-slightly lopsided moon.

The astronomers came up with the scenario to explain why the moon's far side is so much more hilly than the one that is always facing Earth.

Experts said the idea makes sense, but they aren't completely convinced yet.

Three senior nuclear policy officials have been fired in Japan amid scandals suggesting the government had grown too cozy with the nuclear power industry.
