Astronomers discovered a new cosmic object, named 'Punctum,' in the galaxy NGC 4945 using the ALMA radio telescope. This object emits extraordinary brightness, noted to be 10,000 to 100,000 times more luminous than typical magnetars. Observations suggest it persists over time, solidifying its status as more than a mere telescope anomaly or transient phenomenon. The object outshines even central black holes, and its luminance surpasses most known supernovae, making it a subject of significant interest within the astronomical community.
"Everything else disappeared," she told Giz, "even the bright central black hole, and only this little dot remained."
Punctum is astonishingly bright - 10,000 to 100,000 times more luminous than typical magnetars, around 100 times brighter than microquasars, and 10 to 100 times brighter than nearly every known supernova, with only the Crab Nebula surpassing it among star-related sources in our galaxy.
