A Weakened Black Hole Allows its Galaxy to Awaken
Astronomers have found the first example of a galaxy cluster where large numbers of stars are being born at its core. The discovery revealed new details of how supermassive black holes affect their host galaxies.
Towering Balloon-like Features Discovered near Center of the Milky Way
An international team of astronomers has discovered one of the largest features ever observed in the center of the Milky Way – a pair of enormous radio-emitting bubbles that tower hundreds of light-years above and below the central region of our galaxy.
VLA Makes First Direct Image of Key Feature of Powerful Radio Galaxies
A dusty, doughnut-shaped feature long thought to be an essential part of the “engines” at the cores of active galaxies, is seen for the first time in one of the most powerful galaxies in the Universe.
