A star is born—and the James Webb Telescope captured it in stunning detail:
of the star-forming region, enhancing details and eliminating gaps in the original that were left by differences in the magnification capabilities between Hubble’s individual cameras. The result was a massive 33-megabyte file that is nonetheless dwarfed by Webb’s new version, which weighs in at an astonishing 163 megabytes.
The new Pillars of Creation image differs from the well-known Hubble versions not only due to its increased size and resolution, but also because it was imaged in infrared, rather than visual light, which helps pierce the nebula’s thick dust clouds. Hubble does have limited infrared capabilities, and has used them toin 2014, creating another interesting point of comparison with the new Webb image.
Our understanding of the Pillars of Creation has changed over the years. For a time, astronomers believed a supernova had actually destroyed the stellar landscape some 6,000 years ago. But as of 2018, the latest understanding is that the gaseous clouds are still there, continuing to slowly fade away with time as new stars form.
