Strange, repeating radio signal near the center of the Milky Way has scientists stumped

According to a new paper accepted for publication in The Astrophysical Journal and posted on the preprint server arXiv, the energy source is extremely finicky, appearing bright in the radio spectrum for weeks at a time and then completely vanishing within a day. This behavior doesn’t quite fit the profile of any known type of celestial body, the researchers wrote in their study, and thus may represent “a new class of objects being discovered through radio imaging.”
