Researchers Reveal High-Resolution Images of Black Hole

Photonics Spectra
Oct 1998
Scientists may be a little closer to understanding black holes, thanks in part to an imaging technique called IR speckle interferometry. Pioneered by Andrea Ghez of the University of California in Los Angeles, the technique involves using computers to analyze thousands of high-speed, high-resolution images. The images have a resolution that is 20 times superior to Earthbound imaging techniques, according to researchers.

Disappearing stars reveal black hole's presence.

Ghez detected the presence of a black hole in the center of the Milky Way by observing the behavior of 20 stars that exhibited a strong gravitational pull. Those stars spiraled around the black hole at speeds of 3 million mph. Ghez reported her work at the Central Parsecs Galactic Center Workshop '98 on Sept. 7 in Tucson, Ariz.
