The Event Horizon Telescope (EHT) collaboration has observed spirals of light escaping from the edge of the supermassive black hole at the center of our Milky Way Galaxy. The results were published in The Astrophysical Journal Letters.

Radio Observations of Compact Symmetric Objects Shed New Light on Black Hole Phenomenon
Compact Symmetric Objects (CSOs) harbor supermassive black holes that emit powerful jets traveling at near-light speeds in opposite directions. However, unlike their counterparts in other galaxies, these jets remain compact, not extending out to great distances as expected. For decades, scientists presumed that CSOs were youthful entities, with their jets destined to expand over time. New findings, published in three papers in The Astrophysical Journal, challenge this notion.
NRAO and SpaceX Coordinate to Protect Radio Astronomy
Supported by the National Science Foundation, NRAO and SpaceX are developing a system called Operational Data Sharing (ODS) that provides the current status (position in the sky and observing frequency) of two of its telescopes: the VLA in New Mexico and the Green Bank Telescope (GBT) in West Virginia.
Astronomers & Engineers Use a Grid of Computers at a National Scale to Study the Universe 300 Times Faster
Looking for a more efficient way to process a particularly large VLA data set, to produce one of the deepest radio images of the Hubble Ultra Deep Field (HUDF), made famous by the Hubble Telescope, NRAO staff decided to try a different approach.
