最古老的星体

We Found the Oldest Stars in the Universe and They’re Not What We Expected

大爆炸后的几百万年里 一些行星便形成了
Millions of years after the Big Bang, somestars formed.
它们可能是第一批把光带进宇宙的行星
These could’ve been the first stars that brought light into the universe.
这些行星恰恰是在“黑暗时代”后形成的
These stars formed right after the “ DARK AGES ” –
这个时期恰处于
which by the way is the time AFTER
大爆炸之后 出现光之前
the Big Bang but BEFORE there was any light,
此时宇宙充满了黑暗气体
where the universe was filled with just dark gas.
天文学家通过使用电波望远镜在澳大利亚西部
Astronomers found these very first stars by using a radio telescope
发现了第一批行星
out in Western Australia.
电波望远镜非常酷炫 因为它们可以探测到电波
Radio telescopes are cool because they are able to detect radio waves,
也就是宇宙中已知存在的最长波长 这意味着
which are the longest wavelength known to exist in our universe,
电波望远镜可以探测到
meaning it can detect stuff that ’ s traveled
离我们很远的物质
great distances to get to us.
根据宇宙微波背景辐射站探测到的变化
Based on changes detected in the Cosmic Microwave Background Radiation,
天文学家们可以 创造出能解释大爆炸后的180万年的模拟场景
astronomers were able to create models SUGGESTING that 180 million years
这些第一批行星
after the Big Bang, these first stars
就形成了
formed.
这给先前的研究增加了有力证据
This adds to previous research,
现在我们逐渐相信第一批行星
and now we are lead to believe that these first stars
也许是蓝行星
were probably BLUE stars,
根据行星的光谱分类
and based on the spectral classifications of stars we know
我们了解到蓝行星是炽热的 年轻的
that blue stars were hot, young,
寿命很短的一类行星
short-lived stars, that die naturally by a
它们的死亡是由于超新星爆照或者碰撞它的内核 从而形成黑洞
supernova explosion or a collapse of its core into a black hole.
通过使用Murchison Radio 天文气象台的设备
By using instruments at the Murchison RadioAstronomy Observatory, astronomers picked
天文学家们发现了早期宇宙沦陷的频率
up dips in the frequency received from the early universe,
这代表着行星形成的时刻
and THIS represents the moment
和它们与周围世界开始相互制约的瞬间
that stars first formed and began interacting with the matter around them.
这不仅可以让我们对早期宇宙有更好的认识
Not only can this lead us into a better understanding
还有它的
of our early universe, and its evolutionary
发展历程
stages…
但根据科学家们的理论
But according to the scientists,
这可能是暗物质将能量从氢气中吸走
this could possibly be the work of cold dark matter particles
并且将其冷却而形成的作品
pulling energy away from the hydrogen gasand cooling it down.
这都是些推测
This is all speculation of course,
因为我们仍然没有证实暗物质的存在
since we still don’t have confirmation of dark matter existing,
但是这个新发现对此有所帮助
BUT this new info could help it out.
所以让我们期待更多有关的研究结果吧
So let ’ s see what more research
因为了解早期宇宙就意味着 更进一步发现生命的意义
there is to come out of this finding… because understanding the early universe means getting closerto finding the meaning of life.
顺便问一下
Greetings peeps!
喜欢行星这类吗
Like learning about star stuff?
快来看这个视频关于星震的
Check out this video Trace did on starquakes!
最后一件事
One last thing…
这个研究收集到的数据
The data collected from this research came
都是来自大型电波望远镜的天线
from giant radio telescope antennas that are
它与你收音机的天线没有多大区别
not much different than those on your FM radio.
谢谢观看
Thanks for watching.
