Astronomers have recently found that accretion burst happens at different rates over time in our galaxy.
Accretion is the formation of planets and other bodies by the collection of material through gravity.
Sometimes the forming star swallows up a huge amount of matter, resulting in a burst of activities in the massive star. This is called an accretion burst event.
The first observation of accretion burst event was in 2016.
Maser Monitoring Organisation, established in 2017, observes this event using radio telescopes.
