That's no moon. It's not a space station, either.

NASA has discovered a planet 880 light years from earth that is being blasted by a "death" star, reports National Geographic.

The star, known as CoRoT-2a, is pounding the planet with x-rays at a rate of a hundred thousand times more than the earth receives from the sun, reports Discovery News.

Aged somewhere between 100 million to 300 million years old, the star appears to be too close to the planet, known as CoRoT-2b, which might be the cause of the x-ray attack, reports IB Times.

NASA further explains on the Chandra X-ray Observatory website:

This star is pummeling its companion planet -- not visible in this image -- with a barrage of X-rays a hundred thousand times more intense than the Earth receives from the Sun. Data from Chandra suggest that high-energy radiation from CoRoT-2a is evaporating about 5 million tons of matter from the nearby planet every second, giving insight into the difficult survival path for some planets.

X-ray radiation is a behavior usually seen in much younger stars. According to the press release, the planet's proximity may be causing the star to rotate faster, therefore increasing the amount of radiation released by the star.

The findings were published in the Journal of Astronomy and Astrophysics, which highlights new data from NASA's Chandra X-ray Observatory and the European Southern Observatory.

Keeping our planet out of harms way might mean earth has its lucky stars to thank, literally.

Image and illustration of nearby star CoRoT 2a with a planet in close orbit around it.

This graphic contains an image and illustration of a nearby star, named CoRoT-2a, which has a planet in close orbit around it. The separation between the star and planet is only about three percent of the distance between the Earth and the sun, causing some exotic effects not seen in our solar system.

The planet-hosting star is located in the center of the image. Data from NASA's Chandra X-ray Observatory are shown in purple, along with optical and infrared data from the Panchromatic Robotic Optical Monitoring and Polarimetry Telescopes, or PROMPT, and the Two Micron All Sky Survey, or 2MASS. CoRoT-2a is surrounded by a purple glow showing that it is an X-ray source.

This star is pummeling its companion planet -- not visible in this image -- with a barrage of X-rays 100,000 times more intense than the Earth receives from the sun. Data from Chandra suggest that high-energy radiation from CoRoT-2a is evaporating about five million tons of matter from the nearby planet every second, giving insight into the difficult survival path for some planets. The artist's representation shows the material, in blue, being stripped off the planet.

The Chandra observations provide evidence that CoRoT-2a is a very active star, with bright X-ray emission produced by powerful, turbulent magnetic fields. This magnetic activity is represented by the prominences and eruptions on the surface of the star in the illustration.

Such strong activity is usually found in much younger stars and may be caused by the proximity of the planet. The planet may be speeding up the star's rotation, causing its magnetic fields to remain active longer than expected. Support for this idea comes from observations of a likely companion star to CoRoT-2a that orbits at a distance about a thousand times greater than the distance between the Earth and the sun. This star is visible in the image as the faint, nearby star located below and to the right of CoRoT-2a. It is also shown as the bright background star in the illustration. This star is not detected in X-rays, perhaps because it does not have a close-in planet like CoRoT-2b to cause it to stay active.

The planet, CoRoT-2b, was discovered by the French Space Agency's Convection, Rotation and planetary Transits, or CoRoT, satellite in 2008. It is located about 880 light years from Earth and has a mass about three times that of Jupiter.

880光年外行星遭X射线轰击每秒蒸发500万吨
2011年09月17日 09:46:52 　来源： 新浪科技 【字号 大小】【留言】【打印】【关闭】

　　这张配图中左栏是真实的CoRoT-2a图像，右栏则是近距离观察想象图，可以看到围绕它运行的行星CoRoT-2b。真实图像采用多台观测设备数据合成，其中紫色是来自钱德拉望远镜的X射线波段数据，其余则是来自其他观测设备的可见光和红外波段视场叠加。在真实图像中我们不可能看到行星CoRoT-2b，因为它距离恒星的距离极近，其张角仅相当于太阳到地球距离的3%。钱德拉的数据显示它正遭受来自恒星的猛烈X射线轰炸，每秒有500多万吨物质被蒸发消失

　　北京时间9月15日消息，天文学家观测发现一颗近距离恒星正在不断发出强烈的X射线辐射轰击其旁侧的一颗行星，这种辐射的强度要比太阳对地球的辐射高上数十万倍。

　　美国宇航局钱德拉塞卡X射线空间望远镜以及欧洲南方天文台的甚大望远镜(VLT)获取的最新数据显示由于这种剧烈辐射，每秒大约有500万吨物质被从这颗行星表面蒸发掉。这一观测结果让我们得以一窥一部分行星艰难的生存状况。

　　这颗行星的编号为CoRoT-2b ，其质量约为木星的3倍(即大约1000倍地球质量)。它围绕中中央母恒星的公转轨道距离仅约相当于地球-月球距离的10倍。

　　这一星系(包括中央的恒星和围绕它的行星)编号为CoRoT-2，这样编号是因为它最早是法国航天局的“对流，自转和行星掩星”探测卫星(CoRoT)于2008年发现的。这是一颗相对距离较近的恒星体，距离太阳系大约880光年。按照规则，中央的恒星编号为CoRoT-2a，围绕它运行的行星编号为CoRoT-2b。

　　德国汉堡大学的塞巴斯蒂安·施罗特(Sebastian Schroeter)说：“这颗行星几乎被这颗恒星轰炸了。更诡异的是，这颗恒星的行为似乎受到了这颗它轰炸的行星的影响。”

　　根据X射线和可见光波段的观测数据，CoRoT-2系统的年龄估计在1亿~3亿年之间，这就意味着这颗恒星应当已经完全形成了。钱德拉望远镜的观测显示这是一颗非常活跃的恒星，其剧烈的动荡磁场不断爆发出明亮的X射线辐射。而一般认为这类剧烈活动是存在于更加年轻的恒星上的。

　　“由于这颗行星距离其中央的恒星很近，它可能加速了恒星自转，而这会帮助恒星磁场处于持续的活跃状态。”研究论文合著者，同样来自汉堡大学的斯蒂芬·蔡司勒(Stefan Czesla)说。“要不是因为这颗行星的缘故，这颗恒星应当早在数百万年前就已经告别了它狂暴的青少年时代了。”

　　支持这一观点的证据来自对一颗疑似恒星CoRoT-2a的伴星的恒星的观测数据，它距离恒星CoRoT-2a的距离相当于地球-太阳距离的1000倍。这颗伴星不发出X射线辐射，这或许是因为它没有像CoRoT-2a那样的行星围绕运行。

　　行星CoRoT-2b的另一个令人瞩目的特点是它似乎处于膨胀状态。施罗特说：“我们目前还没有办法完全弄清这种剧烈的X射线辐射对于一颗行星的影响，但是它可能正是造成我们在行星CoRoT-2b身上观察到的‘肿胀’的原因。目前我们仍然处于刚刚开始认识在这种极端环境下系外行星问题的阶段。”(晨风)

The universe can destroy any star without giving any mercy nor own any explanation to any party.

This CoRoT-2b is 1000 times larger than earth and it is being fried by X-ray slimming it to a weight lost of 5 million tons per second. That mean vaporising red dot within a min or something like that.
