The pillars of creation in a wonderful form

This is not a mysterious sight of tombs forgotten from time immemorial. They’re not even silly fingers pointing at us. Filled with gas and dust, these plumes “imprison” stars that were slowly forming thousands of years ago. The James Webb Space Telescope This evocative photo was taken by NASA/ESA/CSA surrounded by dust Pillars of Creation In the mid-infrared range – offers us a new perspective on a familiar landscape.

Because the middle infrared light creates a dark and soothing atmosphere in the device image Mary (Mid-infrared instrument) by web? Interstellar dust covers the scene. And while mid-infrared light allows for accurate detection of dust, stars at these wavelengths are not bright enough to be visible. Instead, looming plumes of gas and dust, leaden in color, flicker at the edges, letting the activity taking place within them seep through.

Thousands upon thousands of stars have formed in this region, and this becomes clear when one examines the last image of this object taken from Nircam (Near Infrared Camera) by Webb. In the photo of Meri, most of the stars seem to be absent. How is that? Many newly formed stars are no longer surrounded by enough dust to be detected in mid-infrared light. Therefore, Merry discovers only young stars who have not yet got rid of their dusty “mantle”. They are the scarlet balls on the edge of the columns. By contrast, the blue stars that dot the landscape are aging, which means they have rid themselves of most of their layers of gas and dust.

Mid-infrared is excellent for detecting gases and dust in great detail. This aspect is also visible in the background. The densest areas of dust take on the darkest shades of gray. The ascending red area, forming a peculiar “V”, resembles an owl with outstretched wings, as the dust spreads and becomes colder. It can be seen that no background galaxies appear: the interstellar medium in the densest region of the Milky Way’s disk is so full of gas and dust that it does not allow its distant light to penetrate.

How vast is this landscape? We follow the longer column and reach the bright red star that protrudes from the lower edge. Here: This star and its dust envelope are larger than the size of our entire solar system.

This scenario was first captured by the NASA/ESA Hubble Space Telescope in 1995 and again in 2014, but many other global observatories have also observed this region in depth, such as the telescope. Herschel From the European Space Agency. Each advanced tool provides researchers with fascinating new details about this star-studded region. With each new observation, astronomers and astronomers gain new information and, thanks to constant research, are able to more deeply understand the star formation zone. Each new wavelength and each new advanced instrument provides more accurate values ​​for gas, dust, and stars. The data collected feeds into models used by researchers to study star formation. Thanks to Meri’s new image, astronomers and astronomers now have higher-resolution data in mid-infrared light than in the past, and will be able to analyze dust measurements more accurately to process a more complete 3D view of this remote region.
