for F\u00e9licette<\/a> \u2014 the stray Parisian tuxedo cat who safely completed the world’s first (and only) suborbital feline flight, in 1963 \u2014 as it is for the gargantuan Cat’s Head Nebula, which is featured in stunning new images<\/a> from the Hubble and James Webb space telescopes.<\/p>\n

Rising from the cloudy Carina Nebula<\/a> some 7,500 light-years from Earth, the Cat’s Head Nebula is a column of star-sculpted gas and dust that vaguely resembles a feline sitting with its back to us, coyly turning its head to show off a single red eye. That eye is a young star that’s embedded deep within the dust and possibly transforming it before our eyes.<\/p>\n

<\/p>\n

Nebulas like these occur when the radiation from active young stars lights up and erodes the material around them. They are beautiful and easy to find; if this cosmic cat gets bored staring at us, it can just waltz over to the other side of the Carina Nebula and crawl into a similar globule of gas that looks exactly like a box with an open lid<\/a>. (Cats will be cats<\/a>, after all.)<\/p>\n

In honor of Halloween, the European Space Agency (ESA) shared three competing views of the Cat’s Head Nebula \u2014 one from the Hubble Space Telescope<\/a>, which captures optical light, and two from the infrared instruments aboard the James Webb Space Telescope<\/a> (JWST<\/a>). The three views, shown below, reveal different features of the nebula in different wavelengths of light, getting progressively spookier as more color drains out of the scene.Take a look at all three images \u2014 and cast your vote for the spookiest in the poll at the end.<\/p>\n

Observing the nebula in the same visible wavelength range that you could see through a strong backyard telescope<\/a>, Hubble highlights the dark pillar of dust that has survived the ultraviolet assault of nearby stars. The wispy edges at the right of the column show where starlight is evaporating the gas around it, slowly whittling it away to nothing.<\/p>\n

The glow of blue, yellow, orange and red light around the dust pillar mark where starlight is interacting with different gas molecules, including oxygen, hydrogen and sulfur, according to ESA. The process is similar to how different molecules in Earth’s atmosphere produce different-colored auroras<\/a> when excited by solar radiation \u2014 just on a much grander scale.<\/p>\n

JWST’s near-infrared view<\/p>\n

Switching to light human eyes cannot see, JWST’s Near-Infrared Camera cuts through the wispier outer layers of dust to show the densest material at the column’s center. Countless additional stars and galaxies appear in the field of view as their infrared glow penetrates the surrounding material.<\/p>\n

Here we see a more complex, turbulent column, showing how stellar radiation is carving up the inside of the cat’s head as well as its edges. JWST’s view also illuminates a disembodied, hand-like structure to the left of the cat, reaching out as if to pet its cosmic companion.<\/p>\n

JWST’s mid-infrared view<\/p>\n

The final view, taken with JWST’s Mid-Infrared Instrument, cuts to the ghostly core of the nebula, showing little more than smoky, bluish light. According to ESA, these are the emissions of molecules called polycyclic aromatic hydrocarbons<\/a> \u2014 typically colorless molecules of carbon and hydrogen related to combustion.<\/p>\n

While most starlight disappears in this view, a strange new bright spot emerges to the right of the cat’s head. This orange speck is a true mystery, according to ESA, and its relationship to the rest of the nebula is unknown.<\/p>\n
