Hubble Telescope witnesses a new star being born in a stunning cosmic light show


The infant star FS Tau B is blasting out a powerful jet of matter that is slamming into sounding material.

The Hubble Space Telescope has imaged a powerful jet erupting from a natal envelope of gas and dust that represents a newly born star announcing itself to the cosmos. Once it has accumulated enough mass, the pressure at the heart of FS Tau B will be so great that hydrogen begins to undergo nuclear fusion to create helium in its stellar core. FS Tau B and similar protostars shine not because of nuclear fusion but because of the heat generated by the collapse of the dust cloud that birthed them and from the accretion of more material.
