That's a big baby!
“Stars are born from clouds of gas and dust that collapse under their gravitational attraction. As the cloud collapses, a dense, hot core forms and begins gathering dust and gas, creating an object called a ‘protostar,'”“The dark vertical streak at the center of this image hides OH 339.88-1.26, which is an astrophysical maser,”. Maser is an acronym, much like “laser,” for microwave amplification by stimulated emission of radiation.
Tucked within the dust in the center of the latest image is the massive protostar G339.88-1.26. This very young star, which is still gathering mass from its parent molecular cloud, is already estimated to be about 20 times the mass of the Sun. That is right. Despite being 20 times more massive than the Sun, the baby star G339.99-1.26 is not an especially massive protostar. Consider the protostar G45.47+0.05. It is 30 to 50 times more massive than the Sun and shows evidence of further growth.
