印度科学家在距地球600光年的地方发现行星

HIGHLIGHTS亮点

The discovery was made by measuring the mass of the planet using the PARAS spectrograph integrated with 1.2m telescope in Mount Abu.

这一发现是通过阿布山1.2m带PARAS光谱仪测量的望远镜测量行星质量发现的。

With this discovery, India has joined a select league of countries which has discovered planets around stars.

由于这个发现，印度加入了一个联盟，这个联盟的成员是一些在恒星周围发现行星的国家。

CHENNAI: A team of scientists from the Physical Research Laboratory (PRL), Ahmedabad, discovered a sub-Saturn or super-Neptune size exoplanet, which is about 27 times the mass of Earth and six times the radius of Earth. The planet revolves around a Sun-like star, some 600 light years away from Earth.

金奈：位于艾哈迈达巴德的物理研究实验室的科学家团队发现了一个亚土星或超级海王星大小的外行星, 它的质量约是地球的27倍，半径是地球半径的六倍。这颗行星围绕着一颗太阳般的恒星, 距离地球大约600光年。

The discovery was made by measuring the mass of the planet using the indigenously designed ‘PRL Advance Radial-velocity Abu-Sky Search’ (PARAS) spectrograph integrated with 1.2m telescope at PRL’s Gurushikar Observatory in Mount Abu. With this discovery, India has joined a select league of countries which has discovered planets around stars.

该行星是通过测量地球的质量发现的，使用了印度物理研究实验室在阿布山古鲁希卡的天文台1.2m带PARAS（印度物理研究实验室先进的径向光谱仪）。由于这个发现，印度加入了一个联盟，这个联盟的成员是一些在恒星周围发现行星的国家。

In a post on the website of the Indian Space Research Organisation, scientists said the name of the host star is EPIC 211945201 or K2-236 and the planet will be known as EPIC 211945201b or K2-236b. The planet was found to go around the star in about 19.5 days.

在印度空间研究组织网站上的一篇文章中，科学家们说，宿主恒星的名字是211945201或K2-23，因此这颗行星将被称为史诗211945201B或K2-36B。该行星绕宿主恒星的周期为19.5天。

The surface temperature of the planet was found to be around 600 degrees Celsius, as it is very close to the host star. It is seven times nearer to its star, in comparison with Earth-Sun distance. This might make it uninhabitable.

该行星表面温度约为600摄氏度，因为它离宿主恒星非常近。与地球太阳之间的距离相比，它与恒星的距离是地日距离的七分之一，这可能造成它不太适合居住。

The discovery is of importance for understanding the formation mechanism of such super-Neptune or sub-Saturn kind of planets, that are too close to the host star, according to scientists.

科学家们说, 这一发现对于了解超级海王星或亚土星类行星的形成机制是非常重要的, 因为它们都离宿主恒星太近了。

Paras spectrograph made an independent measurement of the mass of the planet body, as it was necessary for discovery after data from Nasa’s K2 (Kepler2) photometry could not confirm the planetary nature of the system.

PARA光谱仪对行星体的质量进行了独立的测量, 这对此发现十分必要，因为在 Nasa 的 K2 (Kepler2) 光度计的数据无法证实该星系的行星性质。

Initially, it was Nasa’s K2 (Kepler2) photometry that found that the source was a planetary candidate as it was transiting, where the planet body comes between the star and the observer on Earth.

最初，当行星在恒星与地球间活动时，NASA的K2（KePLE2）测光法发现这可能是个行星。

It goes around the star and therefore blocks a tiny amount of star-light. By measuring the amount of light blocked by the planet body, the diameter or size of the planet can be measured. It was found to be 6 Earth radii. However, that data was not sufficient to confirm the planetary nature of the system.

它绕着恒星，因此阻挡了少量恒星的光芒。通过测算被行星阻挡的光的多少，行星的半径或它的大小能够计算出来。由此发现它的半径是地球的六倍。但是这不足以确定系统的行星性质。

PRL scientists, who observed the target for about 1.5 years with the spectrograph to probe the nature of the system, made calculations that suggested that the heavy elements like ice, silicates and iron content make 60%-70% of the total mass.

印度物理研究实验室的科学家们用光谱仪对目标进行了一年半的观测，来探测该系统的性质，计算结果表明重元素如冰、硅酸盐和铁含量占其总质量的60%～70。

This detection was important as it adds to a sparse catalogue of confirmed exoplanets with masses between 10 and 70 MEarth and radii between 4 and 8 REarth, whose masses and radii are measured to a precision of 50% or better.

这个发现十分重要，因为在地球质量10到70倍间以及地球半径4到8倍的太阳系外行星这个稀有的系列里又增加了一个。它们的测量精准达到50%甚至更高。

Only 23 such systems (including the present) are known to this date with such precise measurement of mass and radii.

目前有重量和半径精确测量结果的星系（包含这个）只有23个。

This all discovery is happening due to Modi.. There is no science, and if the scientist is able to achieve anything it only due to blessings of Baba Modi. Hence it should be named as Plant M! Modi Modi Modi Modi!!!

一切的发现都归功于莫迪。没有科学存在，如果科学家能够取得些成果，那只因为受到巴巴莫迪的保佑。所以，这颗行星应该命名为莫迪！莫迪！莫迪！！！！！

Now news channel will run a quiz to name the planet... Then there will be debate; whether it is planet or not; then they found in Modi government so other parties will fight against Modi. BJP will say that Modi has searched and will visit as foreign policy to that planet for claiming land...

新闻频道将搞关于行星命名的摸底……之后必有一番争论；它到底是不是一颗行星。因为是在莫迪政服领导下发现的，其它政党一定会攻击莫迪。人民政党表示，莫迪已经做了研究，按外交政策来说，一定会出访这颗行星，宣告其归属权……

The universe is a mystery and way beyond our imagination. Humans capability is very limited and we can explore beyond a certain level. There could be so many things in the space and even aliens on some other planet. No one knows why we are in this world and yet we destroy ourselves in the name of money, caste, status, politics etc., worse thing is we destroy nature too. We humans are not really fit to live in earth.

宇宙充满奥秘，超乎我们的想象。人类的能力有限，我们只可在一定程度上探索。宇宙空间有很多东西，甚至有外星人。没有人知道为什么我们会在地球上，并且以金钱，种姓，地位，政治等名义毁灭自己；更糟糕的是我们也破坏了自然。
