NASA has again shared a capture made and processed thanks to data collected by the James Webb Telescope, whose beauty and complexity is perhaps unprecedented. Sure the subject helped, but what we had seen so far of the same lens will have to be heavily scaled down because the new image it already promises to be something iconic and will be remembered for years to come.

James Webb has immortalized that area of ​​the cosmos that is universally known as “The Pillars of Creation”made famous by the historic photograph taken by the old Hubble telescope on April 1, 1995.

The area shows columns of interstellar gas and dust within the Eagle Nebula and has been used as one of the reference images for studying star formation for years, as many of the darker areas have been associated with possible protostars and regions. of intense activity of birth of these celestial bodies.

These three-dimensional pillars reminiscent of majestic rock formations, which in some areas appear more vacant and semi-transparent when viewed in near-infrared light. Yet in hindsight we could say that we have not yet seen anything, as Webb’s new vision of the Pillars of Creation will surely lead to a greater understanding of how stars form and explode from these dusty clouds, operations that described in this way seem almost as quick as the blink of an eye, but actually taking place over millions of years.

So let’s take a closer look at this incredible image, which we propose to you for a precise reference alongside the historical one created by Hubble. It is not necessary to specify which is that of the Webb judging by the different levels of detail, however we also propose on the right the one in high definition created by James Webb and shared by NASA.


Given the very high detail returned by the NIRCam (Near-Infrared Camera) of the James Webb it is really difficult to disentangle this image if you do not have some knowledge of what you are looking at, however it is good to know that the newest stars are represented by those bright red spheres and are found mainly in the outer portions of the pillars. It is thought that when formations with sufficient mass are created inside the gas and dust pillars, they begin to collapse under their own gravity, slowly warm up and eventually form new stars.

Wavy lines that look like lava can be seen along the edges of some pillars. It is about ejections of stars that are still forming inside the gas and dust, and as we have observed on other occasions, these periodically launch supersonic jets that collide with clouds of material contained within the pillars. Some of these stars may only be hundreds of thousands of years old, really nothing in astronomical terms.

This area is a simple clipping of the vast Eagle Nebula, which is 6,500 light-years away, and as we reported above, it was first photographed by Hubble in 1995 and revisited in 2014. We propose in closing a video tour released by NASA about this amazing capture while if you want to download the uncompressed and full resolution version you will need to reach this link. Good vision.

UPDATE: NEW MEDIUM INFRARED IMAGE


29/10

NASA published a new elaboration of the area of ​​the cosmos called Pillars of Creation, again based on data collected by the James Webb Space Telescope. It differs from the first as it is a view in the mid-infrared spectrum, captured by the Mid-Infrared Instrument (MIRI) unit and designed to give greater prominence to some details.

The image is almost creepy and suitable for Halloween, as NASA noted, as the areas of gas and dust appear even more gloomy and enveloping. Mid-infrared light is perfect for observing gas and dust in minute detail, so we find that the densest areas of dust are those with darker shades of gray. The upward red region, which forms a mysterious V, like an owl with outstretched wings, is where the dust has spread and is the most recent. We can see that no background galaxies appear in this capture: the interstellar medium in the densest part of the Milky Way’s disk is too bloated with gas and dust to allow their distant light to penetrate.
