A twinkling pulsar reveals invisible structures in space

Phys · · 765 words · By Nina Brinkmann

An international research team used the Effelsberg and FAST radio telescopes to observe the scintillation of pulsar PSR B1508+55. The study revealed ordered structures in the interstellar medium and demonstrated a novel observation technique that utilizes Earth's motion to achieve high resolution.
