A powerful new technique is poised to revolutionize how astronomers observe black holes, by producing sharp, multicolored images that could reveal their dynamic evolution in real time.
By compensating for Earth's turbulent atmosphere, the technique — called frequency phase transfer (FPT) — enables scientists using the global Event Horizon Telescope (EHT) array to see finer details and fainter features of cosmic objects (like black holes) than ever before. This method also improves the frequency of observations by expanding the EHT's limited observation window, allowing scientists to potentially create time-lapse "movies" of black hole activity.
