Citizen astronomers stumbled upon not one but two rings of extragalactic radio signals crossing each other to form a near-perfect Venn diagram. What’s more, the researchers found two more powerful radio signals that offer valuable information about the dynamics of ORCs, first discovered six years ago. Many moving partsThe other two radio signals that the researchers found nearby also support this hypothesis. Professional scientists associated with the RAD@home Astronomy Collaboratory helped assess and confirm the validity of their findings. “The fact that citizen scientists uncovered them highlights the continued importance of human pattern recognition, even in the age of machine learning,” Dabhade added.
