Question

Quizplus · Accepted Answer

The youngest stars in the Orion Nebula and other star-forming regions are surrounded by circumstellar disks and often have jets, which are streams of gas and dust being expelled from the star's magnetic poles. This is due to the fact that these stars are still in the process of forming and are actively accreting material from their surrounding disk, which also drives the formation of the jets.
