Hubble and the James Webb Space Telescope observed a small, active star-forming region in the Carina Nebula, about 7,500 light-years from Earth. The area, nicknamed the Cat’s Head Nebula, appears as a ghostly shape emerging from surrounding gas and dust. Its unusual silhouette draws attention to a larger process: young stars form within dense clouds, while radiation and energy from stars shape the material around them.
In Hubble’s visible-light view, a narrow, opaque pillar of dust resembles a seated cat, with its head turned to one side and a glowing red feature like an eye. A bright rim of gas outlines the dust, while nearby blue regions show ionized gas and scattered starlight; the background shifts through yellow and orange to red. The apparent eye may mark a young star embedded inside the dust. Together, the telescope observations offer different views of this turbulent stellar nursery and its intricate structures, showing how dust, glowing gas, and newborn stars are intertwined.

Long-term zinc creep in cable sockets caused the Arecibo telescope’s support cables to pull out, bringing down its platform in 2020. A National Academies report says Hurricane Maria preceded worsening cable damage and recommends closer monitoring of aging research facilities. (maketecheasier.com)
SpaceX has shifted from relying on government contracts to becoming an essential supplier, giving it more leverage over NASA. Signs of a partial split raise concerns about the agency’s growing dependence on the company. (arstechnica.com)
Mild cold exposure increased production of the metabolite BH2 in worms, with muscle tissue releasing it to support protein balance and tissue health as they age. The findings identify a molecular pathway that may help explain why cold extends lifespan in some animals. (sciencealert.com)
Melting ice in Norway is revealing Stone Age and Bronze Age hunting gear, including arrows up to 6,000 years old. Archaeologists found 48 prehistoric arrows this year, as warming exposes older artefacts once preserved beneath ancient ice. (sciencenorway.no)
NASA is seeking information from commercial companies on servicing Hubble, boosting its orbit, or guiding it into a controlled reentry. The telescope could begin reentering as early as 2032, and NASA says no replacement is expected before the 2040s. (theregister.com)
