“This object was appearing and disappearing ... there’s nothing known in the sky that does that." A few sentences later... It's what's known to astronomers as a transient – an object in the night sky that turns on and off, such as a dying star.  |

“This object was appearing and disappearing ... there’s nothing known in the sky that does that." A few sentences later... It's what's known to astronomers as a transient – an object in the night sky that turns on and off, such as a dying star. A few sentences later... So-called "slow transients" appear over the course of several days and vanish after a few months. One example is a stellar explosion called a supernova. "Fast transients" – such as a type of neutron star called a pulsar – flash on and off within seconds or even milliseconds. The newly discovered object is unusual because it fits neither category, beaming its radio waves across the galaxy in bouts lasting roughly a minute.

I'm pretty certain this exact scenario has happened before it and turned out to be a neutron star with a wobble or something like that, maybe it was flipping, so only part of the time was detectable. It could also be in a binary system and the other object is eclipsing at times, maybe? Total guess on the latter. There is also a star that does this, comes and goes, and speculation is it will go nova in the near future. I'm sure someone will do a video on it with a week or two if it's interesting.
