"Astronomy Domine" is a song by the British band Pink Floyd. The song, written and composed by original vocalist/guitarist Syd Barrett, was the first track featured on their debut album, The Piper at the Gates of Dawn (1967). The lead vocal was sung by Barrett and keyboard player Richard Wright. The video shows Metsähovi Radio Observatory astronomical observatory, which is affiliated with the Aalto University. Its main premises are in Metsähovi, Kylmälä, 35 km west of the campus of the Helsinki University of Technology. The voice in the beginning is from radio astronomer Bob Patterson. He is providing technical data about the observation of a pulsar on May 9th, 1968. The eerie sounds are Saturn's radio emissions captured by NASA's spacecraft Cassini. The radio waves are closely related to the auroras near the poles of the planet. The helicopter like noise is the sound of pulsar PSR B0833-45, the Vela Pulsar. It lies near the centre of the Vela supernova remnant, which is the debris of the explosion of a massive star about 10,000 years ago. The pulsar is the collapsed core of this star, rotating with a period of 89 milliseconds or about 11 times a second.
