ALT A picture of sea ice extending to the horizon, taken from a low-flying aircraft. Where the ocean peeks through the ice is dark blue. Most of the ocean surface is covered in rough-looking white ice, thinner and thicker in some places. Interspersed with the sea ice icebergs. The icebergs have flat tops and sheer edges that rise above the sea ice. At this scope, perspective is hard to tell, but the icebergs rise far out of the water. In the center of the frame, an iceberg dominates. It is cut off to the left of the image, but the visible half looks almost perfectly rectangular, with smooth, straight edges and two precise right angles for corners.
NASA Data Sonification: Black Hole Remix
In this sonification of Perseus, the sound waves astronomers previously identified were extracted and made audible for the first time. The sound waves were extracted outward from the center.
