Pillars of Creation is the name given to the photograph acquired by the James Webb Telescope of NASA. In vast clouds of gas and dust, new stars are forming.
The three-dimensional pillars resemble attractive rock formations, despite the fact that they are more permeable. In near-infrared light, these columns of frigid intergalactic gas and dust appear semitransparent at times.

On Wednesday, the National Aeronautics and Space Administration (NASA) shared photos with jaw-droppingly exquisite detail of the Pillars of Creation that were capture by the Near Infrared Camera (NIRCam) of the James Webb Space Telescope (JWST). The operation of the James Webb Space Telescope shares by NASA, the European Space Agency, and the Canadian Space Agency.
When a photograph of the Pillars of Creation was taken by NASA’s Hubble Space Telescope in 1995, it was at that point that they gained widespread notoriety. These pillars have the appearance of rock formations; however, they are actually three towers of gas and dust that are more porous than they appear. The Pillars of Creation can be seen within the Eagle Nebula, which is sometimes referred to as Messier 16. The Eagle Nebula was found in 1745 by the Swiss astronomer Jean-Philippe Loys de Chéseaux. It is situated in the constellation Serpens and is 6,500 light-years away from Earth.
Astronomers are now able to see more of the dust that is present in the region where stars are forming thanks to a new image taken by NASA’s James Webb Space Telescope in near-infrared light. When the dense, dusty brown pillars become less opaque, more red stars that are still in the process of forming can be see. Within the columns of gas and dust, knots that have accumulated enough mass to start collapsing under their own gravitational attraction, gradually heating up, and eventually giving birth to new stars.
Structure
NASA said that the pillars are similar to buttes that are found in the desert. They are essentially very dense clouds of molecular hydrogen gas and dust that have survived longer than their surroundings while hot newborn stars in the vicinity (which were first pictured at the top of the pillars with the Hubble Telescope and are visible even more clearly with the JWST) throw ultraviolet light in their direction. This light causes the pillars to glow with an ultraviolet light.
Photoevaporation is the term use to describe the process by which high-energy radiation such as ultraviolet light induces changes in the material that it strikes. Because of this occurrence, the pillars are slowly eroding, which reveals the presence of smaller globules of much denser gas buried within them. Evaporating gaseous globules is the name given to these particular globules (EGGs). Embryonic stars begin to form inside of some EGGs. However, once the EGGs are expose, the embryonic stars abruptly stop growing. Because they are no longer in connect to the greater reservoir of gas from which they were drawing mass. After some time, the stars will hatch from their eggs.
James Webb Space Telescope (JWST)
The James Webb Space Telescope embarked on its expedition across space exactly one year ago.
Jane Rigby, an astronomer at NASA and the Operations Project Scientist, states that the James Webb Space Telescope (JWST) ” launches on Christmas day, and then was a present that took six months to unwrap.”
Following an initial phase devoted to calibration, the telescope commenced with the collection of data. And astronomers stun by the initial findings.
“You know, it’s pandemic, we’re all working from home,” Rigby said. “I downloaded the data, and I’m like, sitting in my pajamas,” he said. “After retrieving the facts, I immediately began paging through them and going through them in great detail. And the scenery was breathtaking.”
Even though the telescope’s science mission has only been underway for a little over half a year, it has already revolutionized astronomy. The instruments of the telescope have enabled it to photograph planets, stars, and galaxies in the near and far distances that were not previously observable.
NPR posed this question to three astronomers working in distinct subfields of the field of astronomy. This is to get their perspectives on how the JWST is influencing research in their respective areas. They are unanimous in their assessment that JWST is a paradigm shifter. And they anticipate many more ground-breaking discoveries in the years to come.
The ESA, NASA, and CSA launched this telescope in December 2021.
It’s the successor to the Hubble Telescope and features the most powerful infrared telescope ever built.
This telescope will study galaxies, stars, plants, the big bang, and the evolution of our solar system.
Goal of James Webb Space Telescope
- One of the objectives is to perform a time travel of around 13.5 billion years. In order to investigate how the earliest galaxies and stars emerged from the obscurity of the early universe.
- Second, make a comparison between the earliest galaxies and the grand spirals that exist now. In order to gain an understanding of how galaxies come together over billions of years.
- Third, keep an eye out for the places where new star systems and planetary formations are emerging.
- The fourth goal is to investigate the atmospheres of extrasolar planets and search for the components of life in other parts of the universe.
Researchers will be able to improve their “models of star formation by identifying significantly more precise counts of freshly created stars, coupled with the quantities of gas and dust in the vicinity” with the assistance of the images obtained by the James Webb Space Telescope. Understanding how stars are form and how they emerge from clouds of dust and gas could be much easier thanks to this new information.
