Brian May has just released "New Horizons," his first solo song since 1998. It's actually a joint project with NASA as the New Horizons probe reaches the edge of the solar system.
NASA launched the New Horizons probe in 2006, and on New Year's Day it will perform the most distant flypast in history when it encounters the space object Ultima Thule. Included in the song is the voice of the late Professor Stephen Hawking.
