Jet from HH-47

This Hubble Space Telescope image reveals new secrets of star birth as recorded in a spectacular jet of gas the star has ejected.

Center Image

Resembling the vertebrae of an imaginary space alien, this one-half light-year long jet of gas has burst out of a dark cloud of gas and dust which hides the newly forming star located in the lower left corner of the image.

Upper Left Image

An enlargement of a portion of the jet near the star shows the complicated interactions that take place when the ejected gas collides with the interstellar medium.

Lower Right Image

A massive clump of jet material collides with upstream gas and creates a bow-shaped shock wave, like a boat speeding across a lake.
