الوصفPillars of Creation (NIRCam Image).jpg |
English: 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.
Newly formed stars are the scene-stealers in this Near-Infrared Camera (NIRCam) image. These are the bright red orbs that sometimes appear with eight diffraction spikes. When knots with sufficient mass form within the pillars, they begin to collapse under their own gravity, slowly heat up, and eventually begin shining brightly. Along the edges of the pillars are wavy lines that look like lava. These are ejections from stars that are still forming. Young stars periodically shoot out supersonic jets that can interact within clouds of material, like these thick pillars of gas and dust. This sometimes also results in bow shocks, which can form wavy patterns like a boat does as it moves through water. These young stars are estimated to be only a few hundred thousand years old, and will continue to form for millions of years. Although it may appear that near-infrared light has allowed Webb to “pierce through” the background to reveal great cosmic distances beyond the pillars, the interstellar medium stands in the way, like a drawn curtain. This is also the reason why there are almost no distant galaxies in this view. This translucent layer of gas blocks our view of the deeper universe. Plus, dust is lit up by the collective light from the packed “party” of stars that have burst free from the pillars. It’s like standing in a well-lit room looking out a window – the interior light reflects on the pane, obscuring the scene outside and, in turn, illuminating the activity at the party inside. Webb’s new view of the Pillars of Creation will help researchers revamp models of star formation. By identifying far more precise star populations, along with the quantities of gas and dust in the region, they will begin to build a clearer understanding of how stars form and burst out of these clouds over millions of years. The Pillars of Creation is a small region within the vast Eagle Nebula, which lies 6,500 light-years away. Webb’s NIRCam was built by a team at the University of Arizona and Lockheed Martin’s Advanced Technology Center.فارسی: ستونهای آفرینش با یک کالیدوسکوپ رنگی در تلسکوپ فضایی جیمز وب ناسا به نور نزدیک به نور فروسرخ تنظیم شدهاند. ستونها شبیه طاقها و منارههایی هستند که از منظرهای بیابانی بیرون آمدهاند، اما پر از گاز و غبار نیمهشفاف هستند و همیشه در حال تغییر هستند. این منطقهای است که در آن ستارگان جوان در حال شکلگیری هستند - یا به سختی از پیلههای غبار آلود خود در حالی که به شکلگیری ادامه میدهند ترکیدهاند.
ستارگان تازه شکل گرفته دزدان صحنه در این تصویر دوربین مادون قرمز نزدیک (NIRCam) هستند. اینها گویهای قرمز روشن هستند که گاهی اوقات با هشت سنبله پراش ظاهر میشوند. هنگامی که گرههایی با جرم کافی در ستونها ایجاد میشود، آنها تحت نیروی جاذبه خود شروع به فروپاشی میکنند، به آرامی گرم میشوند و در نهایت شروع به درخشش میکنند. در امتداد لبههای ستونها خطوط مواج وجود دارد که شبیه گدازه است. اینها پرتاب هایی از ستارههایی هستند که هنوز در حال شکلگیری هستند. ستارههای جوان به طور دورهای جتهای مافوق صوت را که میتوانند در درون ابرهای مواد، مانند این ستونهای ضخیم گاز و غبار، برهم کنش کنند، پرتاب میکنند. این گاهی اوقات منجر به ضربههای کمانی نیز میشود، که می تواند الگوهای موجی مانند یک قایق هنگام حرکت در آب ایجاد کند. تخمین زده میشود که این ستارههای جوان تنها چند صد هزار سال سن داشته باشند و تا میلیونها سال به شکلگیری ادامه خواهند داد. اگرچه ممکن است به نظر برسد که نور مادون قرمز نزدیک به وب اجازه داده است تا از پس زمینه عبور کند تا فواصل کیهانی زیادی را فراتر از ستون ها آشکار کند، اما محیط بین ستارهای مانند پردهای کشیده در راه ایستاده است. به همین دلیل است که تقریباً هیچ کهکشانی دور در این منظر وجود ندارد. این لایه شفاف گاز مانع دید ما از جهان عمیقتر میشود. به علاوه، گرد و غبار توسط نور جمعی از "پارتی" پر از ستارههایی که از ستونها ترکیدهاند روشن میشود. مانند ایستادن در اتاقی با نور کافی است که از پنجره به بیرون نگاه میکنید - نور داخلی بر روی شیشه منعکس میشود، صحنه بیرون را پنهان می کند و به نوبه خود، فعالیت در مهمانی داخل را روشن می کند. دیدگاه جدید وب از ستونهای آفرینش به محققان کمک می کند تا مدلهای تشکیل ستارهها را اصلاح کنند. با شناسایی جمعیتهای بسیار دقیق ستارگان، همراه با مقادیر گاز و غبار در منطقه، آنها شروع به ایجاد درک روشنتری از چگونگی شکلگیری و انفجار ستارهها از این ابرها در طی میلیونها سال خواهند کرد. ستونهای آفرینش ناحیه کوچکی در سحابی وسیع عقاب است که در فاصله ۶۵۰۰ سال نوری از ما قرار دارد. Webb’s NIRCam توسط تیمی در دانشگاه آریزونا و مرکز فناوری پیشرفته لاکهید مارتین ساخته شده است. |
