    James Webb Space Telescope reveals new surprises on galaxy organic molecules near black holes
    Maps of the central ∼6″ region of NGC 7469, which includes the AGN and the circumnuclear ring of star formation. Top-left panel: in color and black contours is the JWST/F770W PSF-subtracted image (which mainly traces the 7.7 μm PAH band). Black regions (s1, s2, s3, s4, s5, s6, and s7) correspond to selected circumnuclear zones of NGC 7469. Red and blue regions (o1, o2, o3, o4, o5, and o6) are in the outflow region. The green line represents the orientation of the nuclear molecular gas bar. The gray lines correspond to the approximate outflow region according to the [S IV]λ10.51 μm velocity map (see Appendix B). The white box represents the JWST/MRS ch1 FoV (3.2″ × 3.7″), which is practically identical to the Spitzer/IRS angular resolution...

    First Webb observations of Mars
    First Webb observations of Mars

    NASA’s James Webb Space Telescope captured its first images and spectra of Mars Sept. 5. The telescope, an international collaboration with ESA (European Space Agency) and CSA (Canadian Space Agency), provides a unique perspective with its infrared sensitivity on our neighboring planet, complementing data being collected by orbiters, rovers, and other telescopes.

    Webb’s unique observation post nearly a million miles away at the sun-Earth Lagrange point 2 (L2) provides a view of Mars’s observable disk (the portion of the sunlit side that is facing the telescope)...

    NASA’s James Webb Space Telescope has peered into the chaos of the Cartwheel Galaxy, revealing new details about star formation and the galaxy’s central black hole. Webb’s powerful infrared gaze produced a detailed image of the Cartwheel and two smaller companion galaxies against a backdrop of many other galaxies. The image provides a new view of how the Cartwheel Galaxy has changed over billions of years.

    The Cartwheel Galaxy, located about 500 million light-years away in the Sculptor constellation, is a rare sight...

    Can life Survive a Star’s Death? Webb Telescope can reveal the answer

    When stars like our sun die, all that remains is an exposed core—a white dwarf. A planet orbiting a white dwarf presents a promising opportunity to determine if life can survive the death of its star, according to Cornell University researchers.

    In a study published in the Astrophysical Journal Letters, they show how NASA’s upcoming James Webb Space Telescope could find signatures of life on Earth-like planets orbiting white dwarfs.
