A new study debunks a recent claim that astronomers may have detected a lunar-mass primordial black hole.
In a reanalysis of observations from the Dark Energy Camera (DECam), researchers found that the star nicknamed "Phoebe" was simply doing something ordinary that many stars do: changing its brightness naturally over time. The new findings have been reported in a paper posted to the arXiv preprint server on June 17.
