The air shot when the star 'gave birth'

The ALMA observatory observes the time when the giant air flow was fired, marking the birth of Orion KL Source 1.

A group of astronomers have discovered huge airflows released from Orion KL Source 1 , a star that is forming 1,400 light-years from Earth, according to Phys.

Images obtained from a large radio observatory cluster set in the Atacama desert (ALMA), Chile show air currents fired from the star during its formation."This result gives us important information about the flow of gas, " said Dr. Tomoya Hirota, the lead researcher.

Stars are born from large blocks of dust and gas in space, but astronomers do not understand how giant stars form from this method. An important issue is the rotation of the air mass. The initial cloud turned very slowly, then gradually accelerated as the size shrank due to gravity.

Stars formed from this process should have very high rotational speeds, but current observations show that they rotate much slower. One theory is that the masses of gas fired from the star will reduce the momentum and gradually slow down its speed.

ALMA's observation confirmed this hypothesis. The flow of gas is fired from the edge of the disk of dust and gas, instead of near the young star forming. Dr. Hirota said it would be necessary to study more celestial bodies before this hypothesis could be completed.
