Connecting radio telescopes in Arizona, Chile and Hawaii, astronomers have observed the area around a supermassive black hole with unprecedented sharpness - 2 million times finer than human vision. The observations mark a crucial step toward the scientific goal of the Event Horizon Telescope project: imaging the supermassive black hole at the center of our own galaxy and others.
Researchers are gearing up to take the first picture ever of a black hole. By stringing together radio telescopes across the globe, they are building an Earth-sized virtual telescope powerful enough to see all the way to the center of our Milky Way, where a supermassive black hole is believed to be devouring matter.
Sifting through observation data obtained of more than 2 million galaxies, a research team including UA astronomer Dennis Zaritsky has discovered phenomena telling of stars dying a violent death.
Arizona Radio Observatory's SMT is part of the 'virtual' telescope powerful enough to see a baseball on the surface of the moon.
Magnetized plasma trapped near the black hole is flinging protons into space, where extreme high-energy smashups create high-energy gamma rays.
Astronomers no longer suspect that our Milky Way harbors a central black hole -- they know it.
Berkeley Professor Donald C. Backer is being honored for his research contributions to the discovery of millisecond pulsars.
UA astronomer Jill Bechtold's new survey at X-ray wavelengths of 17 distant quasars including the three most distant quasars yet found supports theory that predicts that supermassive black holes powered the most ancient quasars we see.
Astronomers for the first time have seen matter devoured by a supermassive black hole at the center of our galaxy. Nature today published UA's Fulvio Melia's comments about the discovery, and Melia will talk on about it Sept. 10 for the Steward Public Evening Lecture series.
Working independently, two teams of astronomers have used the new 6.5-meter MMT telescope on Mount Hopkins, Ariz., to discover a massive black hole -- the first ever found in the galactic halo, thousands of light years above the Milky Way galactic plane.
