You may also see any of these images by clicking on the individual images. The "postage stamps" are arranged in a 3 × 3 matrix in order of wavelength: x-ray, blue, visual, red, near infrared pseudocolor, 12µm, 60µm, mm radio maps, and VLA cm radio maps. If a region is blank, then we offer no image at that wavelength, either because we have none or, in some cases, because there is no additional information in that image. After selecting an image, others of the matrix may be selected from a "clickable" colorbar beneath the image.
This object was discovered by Reipurth (1985) in his survey of Nebulous objects in the Orion region. It was first discussed by Reipurth & Bally (1986) as the source of a powerful molecular outflow whose associated reflection nebulosity has only recently appeared in the blue lobe of the outflow. Polarization studies (Scarrott & Wolstencroft 1988) and near infrared imaging (Casali 1991) have demonstrated that the nebula is illuminated by the IRAS source. Recent longslit spectroscopic work (Strom & Strom 1993) has demonstrated that Re 50 is probably a heavily embedded FU Ori object (Hartmann, Kenyon & Hartigan 1993) currently in outburst.
This near infrared pseudocolor image was made by combining the images at J (blue), H (green) and K (red). The shortest wavelength image is mapped into blue and the longest into red, producing the image that you see.
