Maser Monitoring Organisation (M2O)

- Accretion burst event is incredibly rare. Till now, only three such events have been observed, out of all the billions of massive stars in the Milky Way.
- After the first detection of an accretion burst, in 2016, astronomers from around the world agreed in 2017 to coordinate their efforts to observe more.
- Reported bursts have to be validated and followed up with more observations, and this takes a joint, global effort – which led to the formation of the Maser Monitoring Organisation (M2O).
- In January 2019, astronomers at Ibaraki University in Japan noticed that one such massive protostar, G358-MM1, showed signs of new activity.
- The masers associated with the object brightened significantly over a short period of time.
- Follow-up observations with the Australian Long Baseline Array revealed something astronomers are witnessing for the first time – a blast of heat-wave coming from the source and travelling through the surroundings of the forming big star.
- Blasts can last for about two weeks to a few months.
- A maser (microwave amplification by stimulated emission of radiation) is the microwave (radio frequency) equivalent of a laser.
- Masers are observed using radio telescopes and most of them are observed at centimetre wavelength. They are very compact.
- A maser flare can be a sign of an extraordinary event such as the formation of a star.
