Just last October 19, NASA revealed a new capture of the Pillars of Creationcourtesy of the space telescope james webb. Now, and after making the respective comparisons with the version taken by Hubble, the agency has shown the same formation againbut with one big difference: data from another instrument was used of the telescope, where a landscape is revealed”gloomy” and no stars.
In this new image, you have a view that the European Space Agency (ESA) has classified as “chilling”, where the stellar dust covers the entire scene and despite the fact that the infrared light captured by the telescope specializes in detailing where this dust is, the stars are not bright enough at these wavelengths to appear, which leads to the edges glowing, showing the activity they have.
In this region, says the ESA, thousands of stars have formed, and now with the use of the Mid-Infrared Instrument (MIRI), it can be seen that the brightness that would flood the image is missingas it happens in the first observation made.
This is because many newly formed stars are no longer surrounded by enough dust to be detected in mid-infrared light, and MIRI can only see the youngest ones that have not yet “shed” their dust layers, corresponding to a crimson color, at the moment of appreciating them. On the contrary, there are the blue stars, which can be captured in the scene, which, having shed most of their layers of gas and dust, you can see they are getting old.
Thanks to infrared light, it is possible to reveal gas and dust with “extreme detail”according to the ESA, because this also floods the background of the scene, where the densest areas correspond to the darkest shades of gray. In the upper part, within the red region, a “V” is formed, which simulates, says the agency, an owl with outstretched wings, where the dust is diffuse and colder.
Another detail is that background galaxies do not appear either, since the interstellar medium in the densest part of the Milky Way’s disk is overly bloated with gas and dust so that its light can penetrateand is captured by the telescope.
The new information that is revealed thanks to the Webb
This landscape was first photographed by Hubble in nineteen ninety five and again in 2014, in addition to having been the target of other world observatories, such as the ESA’s Herschel. Each time new details have been obtained about the region, that is full of stars.
In addition, thanks to the new observations, scientists can obtain more information about the region, understanding star formation betterbecause with each new wavelength of light and instrument, data on gas, dust and stars can be obtained, which allows fine-tuning the models on how stars form.
In this case, with the new MIRI image, we now have data in mid-infrared light at higher resolution than ever before, which will serve to analyze the dust measurements much more precisely, thus allowing create a more complete three-dimensional landscape of the distant region, located within the Eagle Nebulaabout 6,500 light-years away.
