Thursday Listening Post
Put your headphones on: this is what space "sounds" like
Space is silent to our ears, but telescope data can be turned into sound. Three short listens for tonight, all from NASA and its observatories:
- The center of our galaxy. A region about 400 light-years across, 26,000 light-years away, played as an ensemble: Chandra, Hubble and Spitzer each play a different instrument. Listen at Chandra
- A whole gallery of cosmic sounds. Nebulae, galaxies and star clusters turned into music, one image at a time. Hubble sonifications
- What we sent the other way. In 1977 the two Voyager probes left carrying a golden record of Earth: greetings, music and everyday sounds, in case anyone out there ever listens. See what's on the Golden Record
Tap for the question we're left with
The Golden Record was made for listeners who might never come. If someone did send a record our way, would we know how to play it?
Tomorrow: come back for the next one.
