British astronaut Tim Peake has tweeted his first picture of his view from the International Space Station (ISS).

He has had a busy schedule since joining ISS last week including a strict fitness regime and carrying out experiments for scientists back on Earth.

In his first press conference since reaching the space station, Major Peake said the "blackness of space" was the thing that surprised him most.

"We always talk about seeing the view of planet earth and how beautiful it is so you come to expect that.

"What people don't mention that much is when you look the opposite direction and you see how dark space is - I mean it's the blackest black and you see how small the Earth is in that blackness. That was a real surprise to me."

Alongside posting the picture, Major Peake also retweeted a message from Paul McCartney.

McCartney is the latest musician to send a message congratulating Major Peake on the journey.

Earlier this week Elton Johnwished him luck.

Major Peake thanked the Beatles star and replied that all the crew on ISS are fans of the band.
