تصویری که اسرار کهکشان همسایه ما را فاش می‌کند

تصویری خیره کننده که توسط محققان دانشگاه ملی استرالیا در آژانس ملی علوم استرالیا ثبت شده است جزئیات جدیدی از نزدیک‌ترین همسایه‌ کهکشان راه‌شیری نشان می‌دهد.

به گزارش ایسنا و به نقل از فیز، دکتر “نیکولاس پینگل” (Nickolas Pingel) نویسنده اصلی این مقاله می‌گوید: این واضح‌ترین تصویر ثبت شده تاکنون از خروج هیدروژن از ابر ماژلانی کوچک است.

وی افزود: وضوح این تصویر بی‌سابقه است. ما می‌توانیم تمامی ساختارهای کوچک آن را برای اولین بار مشاهده کنیم. این گام مهمی در جهت درک نقش هیدروژن در تکامل کهکشان‌ها است.

برای مثال می‌توان حفره‌های میان این گاز را مشاهده کرد که نشان دهنده‌ی برهم‌کنش هیدروژن و ابرنواخترها است.

ابرنواختر زمانی رخ می‌دهد که پر جرم‌ترین ستاره‌های کهکشان با انفجاری به زندگی خود پایان می‌دهند.

در این تحقیقات تمرکز بر ابر ماژلانی کوچک بوده است این کهکشان نزدیک‌ترین همسایه اقماری کهکشان راه شیری است.

محققان از تلسکوپ‌ رادیویی ASKAP سازمان پژوهش‌های علمی و صنعتی همسود و نرم‌افزارهای پیشرفته برای ثبت و پردازش ۱۰۰ ساعت از داده‌ها استفاده کردند.

اکنون آن‌ها امیدوارند که این پروژه را یک گام جلوتر ببرند.

دکتر پینگل می‌گوید: سال آینده ما به جمع‌آوری داده‌های بیشتری می‌پردازیم و در نهایت قادریم آن‌ها را به یکدیگر متصل کنیم و نشان دهیم که چگونه این کهکشان به همسایگان نزدیک خود متصل می‌شود.
