Astronomers have discovered an enormous stream of gas flowing toward a young system of three stars, potentially explaining why its planet-forming disks are strangely tilted. Using the Atacama Large Millimeter/submillimeter Array (ALMA), researchers observed a gas streamer stretching about one trillion miles, or 0.2 light-years, toward the young triple-star system GW Orionis. The findings, published […]

After nearly two decades of observations, astronomers have discovered that a distant blazar behaves in ways that leading theories struggle to explain. Instead of solving the mystery of these powerful cosmic objects, the unusually long study has raised new questions about what is happening around their supermassive black holes. Blazars are active galaxies with enormous […]
