It lies within the vast Carina Nebula, a diffuse star-forming region located about 7,500 light-years away from Earth. The small, select area both telescopes observed is nicknamed the Cat\u2019s Head Nebula because of its resemblance to a cat sitting with its back toward the viewer. The \u201chead\u201d of the cat is turned to the right, revealing a glowing eye.<\/p>\n<p class=\"wp-block-paragraph\">Though the Cat\u2019s Head Nebula is a temporary scene that will eventually disperse as stars form and evolve over time, the region is packed with information. Hubble and Webb\u2019s complementary views of the Cat\u2019s Head Nebula are helping astronomers learn more about the elusive, chaotic, and complex process known as star formation.\u00a0<\/p>\n<p><img width=\"611\" height=\"900\" src=\"https:\/\/www.newsbeep.com\/au\/wp-content\/uploads\/2026\/10\/STScI-01M4BZ6G5147CKYXY9C9SY3D9F.jpg\" class=\"attachment-card-md size-card-md\" alt=\"Visible-light image of the Cat\u2019s Head Nebula by the Hubble Space Telescope.

The cat\u2019s head is turned toward the right, revealing a red glowing eye. The top half of the background is bright blue. Approximately halfway down, cutting diagonally across the frame, the background color changes from blue to yellow, orange, and finally red near the bottom. The image is dotted with many small stars. Some larger stars with the telescope\u2019s characteristic four-point diffraction spikes are scattered in the background and foreground.\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" loading=\"lazy\" decoding=\"async\"  \/><\/p>\n<p>NASA\u2019s Hubble Space Telescope shows an opaque dust pillar edged by a luminous rim of gas.

As this stellar feedback erodes the surrounding gas and dust, denser material within the feline-shaped pillar resists erosion, at least for now.<\/p>\n<p class=\"wp-block-paragraph\">Hubble\u2019s visible-light view reveals an opaque, dark brown pillar of dust. The cat\u2019s glowing red eye may indicate a young star that is still partially embedded in dust. A ridge of hazy yellow seems to follow the edge of the filament\u2019s right side. This bright rim is consistent with gas illuminated and ionized by ultraviolet radiation from nearby massive stars, potentially driving a process known as photoevaporation.<\/p>\n<p class=\"wp-block-paragraph\">The diffuse material surrounding the pillar glows blue and cyan above, shifting to yellow, orange, and red toward the bottom. Hubble\u2019s filters capture light emitted by oxygen, hydrogen, and sulfur, along with starlight scattered by dust. These color variations reveal a complex mix of excited gas, dust, and stellar illumination.<\/p>\n<p><img width=\"343\" height=\"900\" src=\"https:\/\/www.newsbeep.com\/au\/wp-content\/uploads\/2026\/10\/STScI-01M4C0TRB0KSNTT73TRKDX7W29.jpg\" class=\"attachment-card-md size-card-md\" alt=\"Near-infrared image of the Cat\u2019s Head Nebula by the James Webb Space Telescope.

While the nebula\u2019s overall structure is similar to the visible-light Hubble image, the filament becomes more transparent, and its complex surface structure becomes discernable in near-infrared light seen by Webb. On the cat\u2019s left are ghostly wisps of dust and gas, delicate structures exposed to radiation from nearby massive stars.<\/p>\n<p class=\"wp-block-paragraph\">Webb\u2019s near-infrared view reveals a dense scattering of stars, shown in blue and yellow. Even in infrared light, some stars are still enshrouded in dust to various degrees. The cat\u2019s eye remains conspicuous. The telescope\u2019s high-resolution imagery even shows faint background galaxies, offering a partial view through our Milky Way galaxy and beyond.<\/p>\n<p><img width=\"900\" height=\"623\" src=\"https:\/\/www.newsbeep.com\/au\/wp-content\/uploads\/2026\/10\/STScI-01M4C1BGFARJ4S0MQHZHD0TPFT.jpg\" class=\"attachment-card-md size-card-md\" alt=\"Mid-infrared image of the Cat\u2019s Head Nebula by the James Webb Space Telescope.

Changes in local conditions and compositions lead to variations in color and brightness. Delicate globules and strands to the pillar\u2019s left are particularly evident in this mid-infrared view.<\/p>\n<p class=\"wp-block-paragraph\">To the right of the pillar, a bright light source is shown as yellow in the mid-infrared image. Likely an infant star embedded in dust, it lies against reddish emission from surrounding material. A narrow filament appears to cross the source, although the image alone cannot establish whether the two are physically related.<\/p>\n<p class=\"wp-block-paragraph\">The Hubble Space Telescope has been operating for more than three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA\u2019s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.<\/p>\n<p class=\"wp-block-paragraph\">The James Webb Space Telescope is the world\u2019s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).<\/p>\n","protected":false},"excerpt":{"rendered":"Like a spectral form rising out of a cold mist, NASA\u2019s Hubble and James Webb Space Telescopes have&hellip;\n","protected":false},"author":2,"featured_media":945428,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[17708,18364,64,63,30300,44337,30301,30302,128,285,1974],"class_list":["post-945427","post","type-post","status-publish","format-standard","has-post-thumbnail","category-space","tag-astrophysics","tag-astrophysics-division","tag-au","tag-australia","tag-goddard-space-flight-center","tag-hubble-space-telescope","tag-james-webb-space-telescope-jwst","tag-nebulae","tag-science","tag-space","tag-stars"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/945427","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=945427"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/945427\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/945428"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=945427"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=945427"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=945427"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
