Le immagini (uniche) del telescopio Webb svelano l’energia di una stella morente

Esa, Nasa e Csa diffondono gli scatti. Gas e polvere espulsi dalla nebulosa planetaria Ngc 1514 catturate grazie al medio infrarosso. È uno scenario cosmico che si è formato nel corso di almeno 4.000 anni

Planetary Nebula NGC 1514 (MIRI image) — The NASA/ESA/CSA James Webb Space Telescope has taken the most detailed image of planetary nebula NGC 1514 to date thanks to its unique mid-infrared observations. Webb shows its rings as “fuzzy,” intricate clumps of dust. It’s also easier to see holes punched through the bright pink central region. [Image description: What looks like a single large, bright star (but is two) shines with bright purple diffraction spikes at the center of a large, diffuse cylinder of gas and dust that is tipped to the right. At the center is a bright pink clumpy cloud that takes up about 25% of the view. There are two large rings seen at a roughly 60-degree angle that appear joined at top left and bottom right. The edges are denser, and form shallow V-shapes that go inward. The rings appear orange at top left and bottom right, and are blue at bottom and center right. There is diffuse orange material around the body. The black background of space is speckled with tiny stars and galaxies mostly in blues and yellows. Areas Webb did not observe are along the top edges, a thin vertical near the nebula at top left, and at the bottom left and right corners.]

Per la prima volta il telescopio spaziale James Webb di Nasa, Esa e Csa ha catturato l’immagine più dettagliata della nebulosa planetaria Ngc 1514 fino ad oggi, grazie alle sue osservazioni uniche nel medio infrarosso.
