The stellar birth process often creates jets that shoot out from the newborn stars. The young stars in these pillars are probably only a few hundred thousand years old and won’t be finished forming for millions of years. When they’re hot and massive enough, fusion will ignite in their cores. They’re still accreting mass, and when they get enough, they’ll collapse under their own gravity and slowly heat up. The protostars as seen by NIRCam are the ones with multiple diffraction spikes. Credit: NASA, ESA, CSA, STScI Joseph DePasquale (STScI), Anton M. It acts like thick smoke or fog, preventing us from peering into the deeper universe, where countless galaxies exist. Dust blocks the view in Hubble’s image, but the interstellar medium plays a major role in Webb’s. Although Hubble highlights many more thick layers of dust and Webb shows more of the stars, neither shows us the deeper universe. Both views show us what is happening locally. Thanks to NIRCam, we can peer right through the gas and dust, lifting the veil on star birth.Ī compare and contrast of a 2014 Hubble Space Telescope view of the Pillars of Creation and the October 19, 2022, JWST image. That view revealed many of the protostars forming inside those cosmic stalagmites in space. Earlier in October, the science teams released a NIRCam (Near Infrared Camera) image of it. The latest steely gray view of the Pillars of Creation set against the glowing red and gray backdrop isn’t JWST’s first rodeo with this region of space. If it did, there’s little evidence of the shock wave hurting the stellar newborns or evaporating the rest of the cloud away. It found evidence of hot gases that suggested a supernova exploded in the area. Spitzer Space Telescope also studied this region of space. The Pillars of Creation have since been imaged again in 2014 by Hubble, as well as by the Chandra X-ray Observatory (which found no x-ray sources associated with the newborn stars). They’re in other stellar nurseries, giving astronomers a good idea of how star birth progresses in thick clouds of gas and dust. Those hungry stellar babies in their cocoons were dubbed “evaporating gaseous globules,” or EGGs. However, they couldn’t see INTO the clouds. When the first Hubble image appeared, astronomers could see the places where stars were born and are eating away at their gas clouds. The blue-looking stars are older ones that have burst free and eaten their birth clouds away.Įagle Nebula Pillars of Creation as seen by Hubble Space Telescope in 2005. They glow a mysterious red-almost like the eyes of jack-o-lanterns-at the tips of formations in the pillars. The red V-shaped region toward the top is where the dust clouds are thinner and cooler.Īt these wavelengths, MIRI is only able to “see” the young stars still embedded in their gas and dust cocoons. The densest areas of dust in the pillars show up as the darkest shades of grey. It reveals gas and dust in intricate detail. Why is this? Mid-infrared light is an important part of the spectrum for astronomers interested in studying clouds of dust. They almost look like cosmic gravestones instead of stellar birthplaces. In the latest image, the Pillars have a steely gray look about them. Thousands of stars are embedded in those pillars, but many are “invisible” to MIRI. This time, data from the MIRI mid-infrared instrument onboard JWST shows a haunting view of the Pillars of Creation. NASA’s James Webb Space Telescope (JWST) just keeps streaming the hits back to Earth.

The NASA/ESA/CSA James Webb Space Telescope’s mid-infrared view of the Pillars of Creation strikes a chilling and ghostly tone.
