CAMBRIDGE, Mass. (UPI) — U.S. astronomers say they’ve taken the closest look ever at the giantin the center of our galaxy and at some of the highest resolution ever made.
By combining telescopes in Hawaii,and , the scientists said they were able to detect structure at a tiny angular scale of 37 micro-arcseconds — the equivalent of a baseball seen on the surface of the moon, 240,000 miles distant.
“This technique gives us an unmatched view of the region near the Milky Way’s,” said Sheperd Doeleman, a astronomer and first author of the study.
“No one has seen such a fine-grained view of thebefore,” said co-author Jonathan Weintroub of the . “We’ve observed nearly to the scale of the horizon — the region inside of which nothing, including light, can ever escape.”
The research is reported in the journal Nature.
