Dark Globule and Stellar Jet in the Carina Nebula

The tadpole-looking feature in the center of this image is a nodule of cold hydrogen gas laced with dust. The image offers circumstantial evidence that a young star is being born inside the placental cloud. The diagonal feature may be caused by twin jets of gas blasting away from the hidden star. They are slamming into neighboring gas to create a pair of bow shocks on either side of the globule. The twisted "tail" on the back of the globule may be evidence for a wobbling jet of material being blasted from the suspected star.

This image is from a mosaic of the Carina Nebula assembled from 48 frames taken with the Hubble Space Telescope's Advanced Camera for Surveys.

About the data

This color image combines many exposures from Hubble Space Telescope's Advanced Camera for Surveys (ACS)* and NOAO/AURA/NSF Cerro-Tololo Interamerican Observatory's (CTIO) 4m Blanco Telescope and MOSAIC2 camera. The ACS data was from the HST proposal 10241 : N. Smith (University of California, Berkeley), J. Bally (University of Colorado at Boulder), N. Walborn (STScI), and J. Morse (NASA/GSFC). *A small area of the Hubble ACS image that was saturated around the brightest star in the field, Eta Carinae, was replaced with images from previous shorter exposures from Hubble's Wide Field Planetary Camera 2.

The CTIO observing team includes: N. Smith (University of California, Berkeley), J. Bally (University of Colorado at Boulder), and J. Walawender (Institute for Astronomy/University of Hawaii). *A small area of the Hubble ACS image that was saturated around the brightest star in the field, Eta Carinae, was replaced with images from previous shorter exposures from Hubble's Wide Field Planetary Camera 2.
