Radio Galaxy Transforms into Blazar, Astronomers Discover

Astronomers have observed a rare case of a galaxy shapeshifting, as a giant radio galaxy named PBC J2333.9-2343 has now been classified as a blazar. The galaxy's core has switched back on, and is now aiming its jet directly towards us. The blazar PBC J2333.9-2343 could give us a deeper understanding of how galaxies can transform, even on human timescales. The research team conducted an extremely thorough investigation, collecting observations in radio, infrared, optical, ultraviolet, X-ray, and gamma-ray wavelengths.
