The “pillars of creation” made iconic and famous by Hubble are revealed in greater depth in this new image taken by the James Webb Space Telescope. What exactly do we see in these structures inside the Great Eagle Nebula? What is it about?
Sooner or laterESAESA and NASANASA were going to delight us with an image of the famous “pillars of creation” taken by the new flagship of the James-Webb space telescopes. It was inevitable! These huge pillars gasgas have been photographed by Hubble several times (in 1995 and 2014, see article below) during its long career that began in 1990. This is one of the “iconic” images of the famous space telescope.

In addition, these “pillars of creation” are an integral part of the huge cloudcloud called the Eagle Nebula or M16M16 (Messier 16). What a beautiful nebula astronomersastronomers amateurs like to contemplate and photograph all summer long and which could also be called the Eagle’s Nest because there are countless stars broodbrood. Many are still in the early stages of their formation, while others are slightly older (a few hundred thousand years) and are warmer and more luminous. We can see them pointing nosenose at the ends turgorturgor which bristle these reliefs.
“Pillars of Creation” which are also a zone of destruction!
Astronomers call them “pillars of creation” because of the stars that are born in the folds of this important concentration of gas and cold dust, but one can also see “pillars of destruction”, or more precisely “pillars in the process of destruction”. These masses casecase are really washed away by jets ultravioletultraviolet powerful massive stars present in the nest. What we see is what remains and still resists stormstorm radiation from these stars, which were also born there, but surround them. As a result, the “pillars” break or crumble, like rocks under pressure waveswaves.
Unlike Hubble, which looks in the visible and infrared, the James Webb Telescope has a penetrating infrared view that allows it to see through, or nearly through, these dense masses of matter. They become translucent and open their own myriadsmyriads hidden treasures A real delight for researchers who, by studying these clouds, hope to better understand the birth and evolution of stars.

Among the countless images produced by the Hubble Space Telescope, one of the most popular is undoubtedly the one with which we discovered the interior of the Eagle Nebula (Messier 16) in 1995. There’s no way your eyes won’t catch her on the corner of a bookstore, on TV, on a magazine cover, in a movie or documentary, on a poster, poster, packaging, or even on a t-shirt… Very photogenic, she’s indeed been photographed several times. traveled the world and is an undeniable witness space cosmetics.
“Pillars of Destruction”
The picture, which has been dubbed the “pillars of creation” since its publication, invites us into the mystery of a cloud of gas and dust pushed by the powerful radiation of massive stars. The scene, which takes place about 6,500 light-years from Earth, instead shows “pillars of destruction,” as noted by researchers involved in this new Hubble composite image released Jan. 5.
Almost twenty years after the first visit, this new version allows us to discover in greater detail than ever before these symbolic structures in the heart of the Eagle Nebula, which extends in the Milky Way towards the constellation Serpent (Cauda snakes). In the transition period, “they (structures) are falling apart before our eyes” comments Paul Scowen, who made the 1995 observations with his former Arizona State University colleague Jeff Hester. “We photograph them at a unique and brief moment of their development. »

These turbulent massive stars, mostly out of focus, were born only a few tens of millions of years ago and are still curling up in their nest. They constantly storm from all sides and attack their bosom. Tighter, the tops of the three pillars continue to resist their blinding blast as best they can. ” [Ils] are ionized, a process by which electronselectrons break away from atoms and are heated by the radiation of these stars– describes Scowen and then eaten away by the mighty the windsthe winds stellar arrays of charged particles that literally “carcherize” the tops of these pillars”.
A situation and environment that can be compared to those that certainly existed elsewhere, in our youth sunsun and all other stars born around it more than 4.5 billion years ago. As evidenced by some inclusions rich in aluminum and calcium (Calcium, aluminum-rich inclusions), found, for example, in the Allende meteorite, a supernovasupernova preceded its genesis. This type of event is the prerogative of swarms of massive stars like the one that’s breaking apart now placentaplacenta the Eagle Nebula. That’s why this scene playing out near us reflects the conditions that once prevailed in the pre-solar nebula.
