Brightest Ever Fast Radio Burst Allows Researchers To Identify Its Origin
An international team of astronomers have observed one of the brightest fast radio bursts (FRBs) ever detected—and pinpointed its location in a nearby galaxy (NGC 4141).
Satellite Internet Meets Space Science: A Groundbreaking Solution for Spectrum Sharing
Researchers from the U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO), in collaboration with SpaceX, have introduced the Operational Data Sharing (ODS) system, a self-reporting framework designed to foster coexistence between radio telescopes and non-geostationary orbit (NGSO) satellite constellations, such as SpaceX’s Starlink.
IMAGE RELEASE: Galaxies in the Perseus Cluster

For galaxies, as for people, living in a crowd is different from living alone. Recently, astronomers used the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) to learn how a crowded environment affects galaxies in the Perseus Cluster, a collection of thousands of galaxies some 240 million light-years from Earth.
Left: The giant galaxy NGC 1275, at the core of the cluster, is seen in new detail, including a newly-revealed wealth of complex, filamentary structure in its radio lobes.
Center: The galaxy NGC 1265 shows the effects of its motion through the tenuous material between the galaxies. Its radio jets are bent backward by that interaction, then merge into a single, broad “tail.” The tail then is further bent, possibly by motions within the intergalactic material.
Right: The jets of the galaxy IC 310 are bent backward, similarly to NGC 1265, but appear closer because of the viewing angle from Earth. That angle also allows astronomers to directly observe energetic gamma rays generated near the supermassive black hole at the galaxy’s core.
Such images can help astronomers better understand the complex environment of galaxy clusters, which are the largest gravitationally-bound structures in the universe, and which harbor a variety of still poorly-understood phenomena.
“These images show us previously-unseen structures and details and that helps our effort to determine the nature of these objects,” said Marie-Lou Gendron-Marsolais, an ESO/ALMA Fellow in Santiago, Chile. She and a number of international collaborators are announcing their results in the Monthly Notices of the Royal Astronomical Society.
