The Beatles' peace anthem Across the Universe has been beamed into outer space by scientists at Nasa.

An avid fan persuaded the US space agency to do it to commemorate the 40th anniversary of the song's release.

Former Beatle Paul McCartney, who beamed his first intergalactic concert to the International Space Station in 2005, congratulated Nasa and asked them to pass on his regards to anyone else out there.

"Amazing! Well done, Nasa!" he said in a statement released by the space agency.

"Send my love to the aliens. All the best, Paul."
