大家好 我是Mike Chang
Hey guys, this is Mike Chang.
浩瀚宇宙有着许多未解之谜
Among the many many mysteries of the universe
其中之一就是近期在红色的火星表面
is the one that concerns the discovery of a deep hole
发现的神秘深洞
in the surface of the red planet or Mars.
这个深洞是美国国家航空航天局
And this was something NASA’s multi-purpose spacecraft
多功能火星勘测轨道飞行器(MRO)
Mars Reconnaissance Orbiter MRO spotted
对火星南极进行拍照时发现的
while capturing snapshots of the planets South Pole.
仔细观察一下照片
Now take a look at this.
这种类型的巨大深坑
The fact that this enormous crater is the first
在过去的11年内也是首次被发现
one of its kind to show up in the last 11 years
火星勘测轨道飞行器(MRO)
that MRO has been exploring Mars,
自2006年3月抵达火星轨道后便一直在进行勘测
ever since it attained the Martian orbit in March of 2006
这使得深洞的发现让人更加困惑
it’s what makes this revelation such a baffling one.
以上是照片揭示的内容
So here’s what the photograph reveal.
火星勘测轨道飞行器装备了高分辨率成像科学实验相机(HiRISE camera)
MROs high-resolution imaging science experiment camera or HiRISE camera
拥有在300公里高度的轨道分辨1微弧
boasts a high resolution of 1 microradian
或是0.3米的火星地表分辨能力
or 0.3 meters at an altitude of 300 kilometers.
这意味着这台高科技相机
What that means is that the high-tech camera
允许研究人员获得具有丰富细节的图像
enables researchers to capture detailed images of objects.
类似从200-400公里的高度
Approximately 3 feet or a meter plus in dimension
看清尺寸约为3英尺或1米的物体
from an elevation of 200 to 400 kilometers.
这进一步表明了近期在火星上发现的这个“坑”
This further implies that the recently discovered pits on Mars
绝对不是一个“小坑”
is by no means a small one.
据推测 这个深坑巨大无比
In fact, it is estimated to be quite vast
可达到几百甚至几千英尺
with hundreds or even thousands of feet.
它覆盖范围如此之大 以至于研究者认为
So much so that it comes across is so big that researchers think that
它可能源于大规模的崩塌或巨大的冲击
it resulted from maybe a massive collapse or a humongous hit.
让我们再来观察一下火星的表面
Also just taking a look at the surface of Mars for a moment here.
火星表面呈现的是氧化铁的颜色
Mars exhibits an iron oxide on its surface,
其特点是在凹陷处有许多撞击坑
that’s characterized by the presence of several impact craters in depressions.
这与火星上山谷 沙漠和极地冰盖所呈现的有所不同
This is apart from the presence of valleys deserts and polar ice caps
火星的岩石表面归因于多种原因
the planets rocky surface is attributed to a plethora of reasons.
如持续的陨石撞击 坍塌的熔岩管
Such as continual meteorite impacts, collapsing lava tubes
早期喷溅的水流和火山活动
blowing water in the early days and volcanic activity.
然而 这些原因用于解释
However, none of these explanations really seems to hold ground.
为什么会在火星表面
When it comes to deciphering
形成这样一个奇怪的深洞时
as to what could have led to the creation of this
似乎都无法成立
strange deep hole in Martian surface.
另外我们可以看一下
Also taking a look at the composition
照片上深洞的构成
of the deep hole from the image taken by MRO.
可以看出近期发现的这个深洞
It appears that the newly discovered crater is
远比旁边的坑洞深很多
much much deeper than the other craters.
旁边的这类坑洞在火星上是非常常见的(火星是太阳系中第二小的行星)
They are commonly cited on the surface of our solar system’s second smallest planet.
研究者同时还在这个巨型的
Also researchers spotted a gleam of ice
熔化干冰深坑底部发现了冰存在痕迹
at the bottom of this vast pit of melting frozen carbon dioxide.
除了巨坑本身
In apart from the pit itself.
天文学家们还发现了在巨坑周围
Astronomers witnessed patches of frozen carbon dioxide
冰雪覆盖的区域上点缀着干冰斑点
dotting the ice-covered area around the hole.
这些圆形的斑点被认为是
These circular patches are thought to be the regions
干冰 即冰冻的二氧化碳
where dry ice or frozen carbon dioxide had its sublimed own way
在太阳照射到火星南极时进行升华形成的
under the heat of the summer sun at Mars’ south pole.
整个区域看起来像一块瑞士奶酪
Basically, this whole area is kind of looks like a Swiss cheese.
这就是为什么天文学家称之为瑞士奶酪地形
That’s why astronomers call it the Swiss cheese terrain.
所以说 火星表面虽然有大量的坑洞
So basically there are a lot of craters on Mars.
但是没有人能弄清楚
But no one really has a clue as to
这个巨大巨深的坑洞是如何形成的
how this this massive and deep of one was created.
但是 人们已经在努力缩小形成这种构造
But there are efforts right now to narrow down the possible causes
可能原因的范围
that could have led to this formation.
当然 外星人大战没有考虑在内
Of course, alien war would not be considered,
但是直到美国国家航空航天局给出一个令人信服的理论之前
but till such time NASA comes up with a convincing theory.
这个远深于平均凹陷处的深洞的起源
The origin of this deeper than the average depression
依然是一个猜谜游戏
will remain a guessing game for all.
所以你也可以来试试猜一下
So take your best guess what do you think caused us
是什么导致了深洞的存在
massive deep hole on the surface of Mars.
你可以写在下面评论处
Let me know your thoughts in the comments below.
非常感谢您的观看 下次再见
Thanks so much for watching, I’ll see you later.
