7,500 Light-Years From Earth, A Cat’s Head Appears

A stunning new image from NASA showcases the Carina Nebula, revealing a cat's head emerging from the vast cloud of gas and dust. This eerie sight, dubbed the Cat's Head Nebula, has been newly recognized but is not a recent discovery. Located approximately 7,500 light-years away from Earth, this cosmic cat was shaped over millennia by the intense ultraviolet radiation and powerful winds of the nearby massive stars.

The distinctive eye of the cat is believed to be a newborn star, still veiled by a dust-covered pillar stretching beneath it. The Hubble Space Telescope image captures the nebula in visible light, displaying yellow ridges caused by gas ionized by ultraviolet radiation. Astronomers theorize that photoevaporation, or the dispersal of gas heated to such an extent that it effectively boils off, might be occurring here.

In the two James Webb Space Telescope images, the same scene is portrayed in near-infrared and mid-infrared wavelengths, light that is not visible to the human eye. The near-infrared image reveals starlight partially obscured by dust, providing a glimpse of the cat's transparent body and the background, while the orange dust filaments remain visible.

The mid-infrared image is the most ethereal, showcasing the ghostly appearance of the nebula, which resembles a spectral feline standing watch in space. The white outlines are created by the warmth of the dust and carbon-based molecules that comprise the Cat's Head Nebula. As with all images from these telescopes, the colors are chosen during the image-processing stage; the telescopes capture light readings in grayscale.
