有迹象表明，这可能是第一次被探测到一颗行星在银河系外穿过恒星的迹象 这可能是第一次探测到行星在银河系外穿过恒星的迹象。这个有趣的结果，利用NASA的钱德拉X射线天文台，打开了一个新的窗口，可以在比以往更远的距离搜索系外行星。 这颗可能的候选系外行星位于螺旋星系梅西耶51（M51）中，也因其独特的外形而被称为漩涡星系。 系外行星被定义为太阳系之外的行星。到目前为止，天文学家已经发现了银河系中所有其他已知的系外行星和系外行星候选行星，几乎所有这些行星都距离地球不到3000光年。M51中的一颗系外行星距离我们大约2800万光年，这意味着它的距离是银河系中的行星的数千倍。 系外行星被定义为太阳系之外的行星。到目前为止，天文学家已经在银河系中发现了所有其他已知的系外行星和系外行星候选者，它们几乎都离地球不到大约3000光...
This celestial lightsaber does not lie in a galaxy far, far away, but rather inside our home galaxy, the Milky Way. It’s inside a turbulent birthing ground for new stars known as the Orion B molecular cloud complex, located 1,350 light-years away. 这把天体光剑并不在遥远的星系中，而是在我们的家园银河系中。它位于一个名为猎户座B分子云复合体的新恒星的湍流诞生地内，距离我们1,350光年。 Image Credit: NASA/ESA 图片来源：NASA/ES...

The Hubble Space Telescope’s glamour shots of the universe nearly always have a discovery behind them. 哈勃太空望远镜拍摄的迷人的宇宙照片背后几乎都有一个发现。 In this image, a remote galaxy is greatly magnified and distorted by the effects of gravitationally warped space. After its public release, astronomers used the picture to measure the galaxy’s distance of 9.4 billion...
