Very cool. Does anyone know why some areas are somewhat blueish. And what about the very bright stars?

- wl 14y agoThe colors are a bit arbitrary. The sensor that takes these images only records intensity and not color. Different filters are placed over the sensor to record different wavelengths. Not all of these wavelengths are visible light. The colors are a mapping of these wavelengths to the visible spectrum.
- bitJericho 14y agoThe very bright stars are just very close, dozens of lightyears instead of hundreds or thousands.
