Later, it was determined that the phenomenon was actually the bright light of a supernova, or exploding star, reaching Earth.  <\/p>\n<p class=\"paragraph inline-placeholder\">      Having historical evidence of a stellar explosion event is rare, which is why there is so much interest in the nebula.  <\/p>\n<p class=\"paragraph inline-placeholder\">      Despite the fact that the relatively nearby Crab Nebula has long been observed, modern astronomers still have questions about the doomed star and the chemical makeup of the glowing cosmic cloud it created.  <\/p>\n<p class=\"paragraph inline-placeholder\">      The Crab Nebula has been studied by other space observatories like the Hubble Space Telescope. But Webb\u2019s ability to view the universe in infrared light, which is invisible to the human eye, was able to pierce through the otherwise obscuring dust of the nebula to pick out previously unseen features.  <\/p>\n<p class=\"paragraph inline-placeholder\">      Researchers used Webb\u2019s Near-Infrared Camera and Mid-Infrared Instrument to study the nebula with the aim of unveiling insights into its origins.  <\/p>\n<p class=\"paragraph inline-placeholder\">      \u201cWebb\u2019s sensitivity and spatial resolution allow us to accurately determine the composition of the ejected material, particularly the content of iron and nickel, which may reveal what type of explosion produced the Crab Nebula,\u201d said Tea Temim, research astronomer at Princeton University in New Jersey, in a statement.  <\/p>\n<div class=\"image-slider\">\n<div class=\"image-slider__container\">\n<div class=\"image-slider__image-container\">\n<div class=\"image-slider__image-before\"><\/div>\n<div class=\"image-slider__image-after\"><\/div>\n<\/div>\n<\/div>\n<div class=\"image-slider__caption\">\n<div class=\"image-slider__title\"><\/div>\n<div class=\"image-slider__credit\">\n<p class=\"image-slider__credit-text\">\n<\/p><\/div>\n<\/div>\n<\/div>\n<h3 class=\"subheader\">    Capturing aspects of the ever-expanding Crab Nebula<\/h3>\n<p class=\"paragraph inline-placeholder\">      Hubble captured the celestial object using an optical wavelength in 2005 (above left), while Webb\u2019s latest infrared image (above right) revealed more of its structural details and inner workings.  <\/p>\n<p class=\"paragraph inline-placeholder\">      Yellow-white and green filaments, made of dust grains, appear in the Webb image for the first time. The prominent smokelike material that dominates the nebula\u2019s interior is evidence of synchrotron radiation, or patterns created by charged particles moving around the lines of magnetic fields.  <\/p>\n<p class=\"paragraph inline-placeholder\">      This milky haze is produced by the nebula\u2019s power source, a pulsar, or a rapidly rotating neutron star. Neutron stars are the dense remnants that form after massive stars burn through their internal nuclear fuel and collapse. The pulsar\u2019s magnetic field accelerates charged particles to the point that they emit radiation as they zoom around the star\u2019s magnetic field lines.  <\/p>\n<p class=\"paragraph inline-placeholder\">      In the new image, rippling, circular wisps point to the nebula\u2019s pulsar heart, seen as a central bright white spot. Closer to the edges of the image are thin white lines that outline the pulsar\u2019s magnetic field, which provides the nebula with its shape. The nebula continues to expand over time as wind created by the spinning pulsar pushes the interior gas and dust outward.  <\/p>\n<p class=\"paragraph inline-placeholder\">      As astronomers continue to analyze the Webb data and compare it with data collected by other telescopes, they are also anticipating a fresh perspective on the nebula from Hubble within the next year. Together, the observations could help astronomers turn back time to unlock what happened before the star exploded.  <\/p>\n\n<div>This post appeared first on cnn.com<\/div>","protected":false},"excerpt":{"rendered":"<p>The James Webb Space Telescope has captured wispy new details of cosmic gas and dust within the Crab Nebula, revealing insights into what happens in the aftermath of a massive star explosion.
