Phys.org / Slow changes in radio scintillation can nudge pulsar timing by billionths of a second

For 10 months, a SETI Institute-led team watched pulsar PSR J0332+5434 (also called B0329+54) to study how its radio signal "twinkles" as it passes through gas between the star and Earth. The team used the Allen Telescope ...
