Compass and Scale Image for Protostar IRAS 20324+4057
4,500 light-years (1,380 parsecs)
The image was created from Hubble data from proposal 10536: R. Sahai (Jet Propulsion Laboratory), M. Morris (UCLA), C.S. Contreras (CSIC/INTA), M. Claussen (Associated Universities, Inc.), and S. Salim (Indiana University).
The science teams include: N. Wright, J. Drake, M. Guarcello, and L. Hora (Harvard-Smithsonian Center for Astrophysics), J. Drew (University of Hertfordshire), R. Gutermuth (University of Massachusetts, Amherst), and K. Kraemer (Harvard-Smithsonian Center for Astrophysics/Boston College); and R. Sahai (Jet Propulsion Laboratory), M. Morris (UCLA), and M. Claussen (Associated Universities, Inc.).
ACS/WFC: F606W (V) and F814W (I)
Note: Hubble data of IRAS 20324+4057 have been combined with ground-based H-alpha observations taken in 2003 with the Isaac Newton Telescope (INT) to create the composite image.
This image is a composite of separate exposures acquired by the ACS instrument and the Isaac Newton Telescope. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:
Blue: F606W (V)
Orange: F814W (I)
