ウェッブ宇宙望遠鏡は、創造の柱の信じられないほどの星がいっぱいの写真を撮ります

近赤外光は構成星の大きな星座を明らかにし、その多くはまだ塵に囲まれています

James Webb Space Telescope’s Near-Infrared Camera captured this glittering view of the Pillars of Creation – and it begs to be examined pixel by pixel. It is a stunning scene that may look both familiar and entirely new at the same time. It was first captured by NASA’s Hubble Space Telescope in 1995 and followed up in 2014, and many other telescopes have deeply gazed at this scene. However, this is the first time an observatory has delivered such detailed data in near-infrared light. Newly formed stars pop out in shades of pink, red, and crimson. Still-forming stars that remain hidden deep in dusty pillars resemble molten lava, and fully-formed blue and yellow stars sprinkle the scene.

Where are the galaxies that often “photobomb” Webb’s images? The pillars are located directly in front of our Milky Way galaxy’s disk, which blocks our view of the galaxies that lie behind it. It is also lit up by the collective light from the packed “party” of stars. With these new data, researchers will be able to update complex models of star formation with even more precise star counts and dust quantities. It is clear that we are about to learn a whole lot more about how stars form.

The Pillars of Creation are set off in a kaleidoscope of color in NASA’s James Webb Space Telescope’s near-infrared-light view. The pillars look like arches and spires rising out of a desert landscape, but are filled with semi-transparent gas and dust, and ever-changing. This is a region where young stars are forming – or have barely burst from their dusty cocoons as they continue to form. Credit: NASA, ESA, CSA, STScI; Joseph DePasquale (STScI), Anton M.

NASA’s Webb Takes Star-Filled Portrait of Pillars of Creation

In exquisite detail, NASA’s James Webb Space Telescope has captured a lush, intricate landscape – the iconic Pillars of Creation. This is a region where new stars are forming within dense clouds of gas and dust. The three-dimensional pillars resemble majestic rock formations, but are far more permeable. These columns are made up of cool interstellar gas and dust that appear – at times – semi-transparent in near-infrared light.

Webb’s new view of the Pillars of Creation, which were first made famous when imaged by NASA’s Hubble Space Telescope in 1995, will help astronomers revamp their models of star formation by identifying far more precise counts of newly formed stars, along with the quantities of gas and dust in the region. Over time, they will begin to build a clearer understanding of how stars form and burst out of these dusty clouds over millions of years.

Pillars of Creation (Hubble and Webb Images)

NASA’s Hubble Space Telescope made the Pillars of Creation famous with its first image in 1995, but revisited the scene in 2014 to reveal a sharper, wider view in visible light, shown above at left. A new, near-infrared-light view from NASA’s James Webb Space Telescope, at right, helps us peer through more of the dust in this star-forming region. The thick, dusty brown pillars are no longer as opaque and many more red stars that are still forming come into view. Credit: NASA, ESA, CSA, STScI; Joseph DePasquale (STScI), Anton M. Koekemoer (STScI), Alyssa Pagan (STScI).

Newly formed stars are the scene-stealers in this stunning image from Webb’s Near-Infrared Camera (NIRCam). These are the bright red orbs that typically have diffraction spikes and lie outside one of the dusty pillars. When knots with sufficient mass form within the pillars of gas and dust, they begin to collapse under their own gravity, slowly heat up, and eventually form new stars.

What about those wavy lines that look like lava at the edges of some pillars? These are ejections from stars that are still forming within the gas and dust. Young stars periodically shoot out supersonic jets that collide with clouds of material, like these thick pillars. This sometimes also results in bow shocks, which can form wavy patterns like a boat does as it moves through water. The crimson glow comes from the energetic hydrogen molecules that result from jets and shocks. This is evident in the second and third pillars from the top – the NIRCam image is practically pulsing with their activity. These young stars are estimated to be only a few hundred thousand years old.

近赤外光がウェブを雲に「浸透」させてプルームの背後にある大きな宇宙距離を明らかにしたように見えるかもしれませんが、このビューには銀河はありません。 代わりに、天の川の円盤の最も密度の高い部分にある星間物質として知られる透明なガスと塵の混合物が、最も内側の宇宙の視界を覆い隠しています。 (星間物質は、銀河の星の間に分散したガスと塵です。主に、水素原子、分子、および固体の塵粒子で構成されています。)

このシーンを最初に撮影したのは 1995年のハッブル そしてその 2014年改訂、しかし、他の多くの天文台がこの地域を深く見つめていました。 各高度なツールは、事実上星であふれているこの地域に関する新しい詳細を調査員に提供します。
