哈勃望远镜在IC2631中发现新形成的恒星
Stars are born from clouds of gas and dust that collapse under their own gravitational attraction. As the cloud collapses, a dense, hot core forms and begins gathering dust and gas, creating an object called a “protostar.” 恒星是由气体云和尘埃在自身引力作用下坍缩而形成。随着云团坍缩,会形成一个致密、炽热的核心,并开始聚集尘埃和气体,形成一个称为“原恒星”的物体。 This Hubble infrared image captures a protostar designated J16728...
