While these two images may look dazzlingly different, they are actually pictures of the same cosmic object: NGC 1850. Although the same Hubble instrument took both images, different filters with different assigned colors were used to study particular wavelengths of light emanating from these objects. The image with blue nebulosity includes some near-infrared light along with visible light (what our human eyes can detect), whereas the image with red nebulosity (also a different "pointing" at the same object) covers a much broader range from the near-ultraviolet to the beginnings of the infrared spectrum. Ultraviolet observations are ideal for detecting the light from the hottest and youngest stars, as seen in this luminous, starry view.
