| Description: | This nebula has been the subject of much investigation recently due to the discovery of a high mass protostar that has a diameter of about 10 of our Solar Systems. A protostar is a mass of gas and dust that is collapsing to form a star. Protostars are hard to study because they are born in obscured regions. Methanol masers are often used to penetrate these obscuring regions and provide information about this little understood process. | |
