I'd love to understand how those bright dots and lines (so, cosmic rays?) appear on these images.

- xioxox 7y agoThey're just high energy particles that interact with the CCD cameras typically used for astronomy. You get a bright point or particle track, as the particle interacts with the CCD producing electrons. This is worse for space telescopes, as there are more cosmic rays in space.
