[LEFT] This is the Carina Nebula as imaged by ground-based telescopes at the Cerro Tololo Inter-american Observatory (CTIO) in La Serena, Chile. Narrow-band filters which allow emission from oxygen, hydrogen, and oxygen were used to create this multi-colored image. The white box outlines the Hubble Space Telescope/CTIO Carina Nebula mosaic, released in 2007. Image courtesy of N. Smith (University of California, Berkeley) and NOAO/AURA/NSF.
[TOP RIGHT] This is the Hubble Space Telescope/CTIO mosaic of a subsection of the Carina Nebula. CTIO emission filters were combined with Hubble Advanced Camera for Surveys (ACS) data taken with filters that isolate hydrogen emission. This higher-resolution ACS image was used as a luminosity layer and combined with the multi-filtered CTIO data. The white box outline indicates the Carina Nebula dust pillars.

[BOTTOM RIGHT] This is a photo of the Carina Nebula dust pillars imaged with Hubble's Advanced Camera for Surveys (ACS) detector using filters that allow emission from hydrogen (from 2005 data) and oxygen (2010 data). The recent oxygen observations were a "bonus" dataset that resulted when the ACS was used "in parallel" with the Wide Field Camera (WFC) as that detector imaged Herbig-Haro objects 901/902 in February 2010 for Hubble's 20th Anniversary image release.
