Показать описание
An image of galaxy cluster Abell 370 taken by the Hubble space telescope is converted directly into sound. Time flows from left to right and the frequency of sound changes from bottom to top, so that objects near the bottom of the image are heard as the lowest tones. Compact galaxies create brief tones while elongated spiral galaxies produce longer notes that can change pitch. Listen for the two massive elliptical galaxies near the cluster's core and the bright foreground star at the bottom right. The cluster's enormous mass (mostly dark matter) warps spacetime so that it acts like a giant magnifying lens. This distorts the image of more distant galaxies creating arcs such as 'The Dragon' just below the large elliptical galaxy on the bottom left.
