Bipolar Outflow (Young Stellar Objects)

Imagem de um outflow bipolar a comprimentos de onda ópticos - par de blobs de emissão cujo visível tem origem num gás choqu'excitado interagindo com um vento bipolar escondido de alta velocidade gerado por uma protoestrela invisível de classe I localizada no cerne negro entre os dois lobos.

HST image of a bipolar outflow at optical wavelengths. The two blobs of emission are the Herbig–Haro objects 1 and 2. The visible emission originates in shock-excited gas interacting with a hidden high-velocity bipolar wind generated by an invisible class I protostar located in the dark cloud core between the two lobes.
