Researchers at the SETI Institute have been monitoring a pulsar's flickering pattern for months, which has led to discoveries about the distortion of radio signals in space. The study of the pulsar's "twinkle" is revealing the hidden texture of space, although the exact nature and implications of the findings are not entirely clear. It is also unclear if the pulsar is related to other recent discoveries, such as an ultra-fast pulsar near the Milky Way's supermassive black hole or a potential solution to a century-old cosmic ray mystery.
