It's a ____1____ worthy of an action film - galaxies, violently torn apart, smashing into one another, leaving remnants of themselves behind billions of years later. That's the scene that ____2____ some of the oldest stars in our own Milky Way galaxy, according to work published in the journal Monthly Notices of the Royal Astronomical Society.
Researchers ran a huge computer simulation of the evolution of the universe starting shortly after the big bang, more than 13 billion years ago. It's the most detailed model ever produced, and allowed a close examination of the make-up of the Milky Way's stellar halo. The stellar halo is ____3____ that surrounds our familiar white swirl of stars. The halo is much larger and much older than the Milky Way itself.
And the simulations show that the ancient stars in the halo were formed from young, small galaxies that ____4____ and left behind fragments of themselves, ____5____ those stars actually being born in the Milky Way when it started forming 10 billion years ago. The researchers say the scene ____6____ the dramatic - and violent - clashes that were taking place long, long ago, in a galaxy not very far away.

plotline accounts for debris collided as opposed to depicts
這樣的情節(jié)都能拍成動作大片了：星系們相互撕扯著，驟然四分五裂，彼此猛烈碰撞，僅留殘余碎片在億萬年后的今天。而這一幕恰恰解釋了銀河系里面最古老的恒星是從何而來的，《皇家天文學(xué)會月刊》上的一篇文章如是說。 研究人員通過運行巨型計算機來模擬130多億年前宇宙大爆炸發(fā)生不久之后的宇宙演化過程，這是有史以來最為詳盡的宇宙模型，并對銀河系恒星暈的構(gòu)成進行了細致的觀測。恒星暈就是我們所熟知的恒星外圍環(huán)繞著的白色漩渦狀光暈，由恒星殘骸構(gòu)成。而這光暈比銀河系本身還要廣袤、古老。 計算機模擬表明，光暈中的古老恒星由年輕、幼小的星系相互撞擊所余留的碎片而形成，并非是100億年前銀河系初形成時誕生的恒星。研究人員說這一場景描繪了很久很久以前，離我們不遠處的一個星系內(nèi)部壯觀而暴烈的纏斗撞擊。
