W33A
Appearance
W33A is a protostar located approximately 12,000 light-years away from Earth, in the constellation Sagittarius. As a star in the early stages of formation, the star has attracted the interest of astronomers, who obersved that while the star is accumulating material from surrounding clouds of gas and dust, it is simultaneously ejecting fast moving jets of particles from its north and south poles.[1]
