NICMOS Image of Jet Near HH 1

An infrared image obtained with the NICMOS camera onboard the Hubble Space Telescope at a wavelength of 1.6 um showing the region around the energy source of the HH 1 & 2 jet. The primary jet is clearly visible in [Fe II] emission all the way to the location of the embedded VLA source. An arc-shaped reflection nebula at lower left opens up towards a seconda ry HH flow. Hence, a companion to the VLA source must be located near the apex of the nebula. The two flow axes are indicated. The scale bar of 2" corresponds to ~ 920 AU at the distance to these jets.
