Across the Universe is an interstellar radio message (IRM) consisting of the song "Across the Universe" by the Beatles that was transmitted on 4 February 2008, at 00:00 UTC by NASA in the direction of the star Polaris.
[1] This transmission was made using a 70-meter "DSS-63" dish in the NASA Deep Space Network's (DSN) Madrid Deep Space Communication Complex, located in Robledo, near Madrid, Spain.
The event marked the third time a song had ever been intentionally transmitted into deep space (the first being Russia's Teen Age Message in 2001, and the second being the 2003 Cosmic Call 2 message which included "Starman" by David Bowie and music from the Hungarian band KFT),[2][3] and was approved by Paul McCartney, Yoko Ono, and Apple Records.
The compressed digital format used makes the data more fragile to errors compared to TAM's analogue approach, not to mention aliens would not have knowledge on human audio compression algorithms.
Finally, the choice of Polaris also makes the message unlikely to reach any alien lifeform should they exist.
