A complex nebula fills the frame that is brightly colored, with red being prominent in the image center and blue being most prominent elsewhere. Stars also dot the image. Please see the explanation for more detailed information.
复杂的星云充满了整个画面，色彩鲜艳，红色在图像中心尤为突出，蓝色在其他地方最为明显。星光也点缀在图像中。有关更多详细信息，请参阅说明。
利用NASA钱德拉X射线天文台进行的一项新研究显示，从距离地球1140万光年的近邻星系NGC 253中心发出的强风的影响。这种星系风由温度高达数百万度的气体组成，这些气体以X射线的形式发光。每年都有相当于200万个地球质量的热气体从银河系中心吹出。
Infrared light surges out from the Dumbbell Nebula, also known as Messier 27, in this Aug. 10, 2011, image from NASA’s Spitzer Space Telescope. This nebula was discovered in 1764 by Charles Messier. It was the first in a class of objects, now known as planetary nebulae, to make it into Messier
This Jan. 10, 2013, composite image of the giant barred spiral galaxy NGC 6872 combines visible light images from the European Southern Observatory’s Very Large Telescope with far-ultraviolet data from NASA’s Galaxy Evolution Explorer (GALEX) and infrared data acquired by NASA’s Sp
由蒙特利尔大学的研究人员领导的一个团队发现了证据，表明围绕一颗红矮星运行的两颗系外行星是“水世界”，水在整个行星中占了很大一部分。这些行星位于天琴座218光年外的一个行星系中，不同于我们太阳系中发现的任何行星。
While observing the outer region of the Milky Way galaxy, our Spitzer Telescope captured this infrared image of a cloud of gas and dust that looks like the hollowed-out pumpkins we see every Halloween. Nicknamed the “Jack-o’-Lantern Nebula,” it was likely created by powerful outflows of radiation an
What looks like a red butterfly in space is in reality a nursery for hundreds of baby stars, revealed in this infrared image from NASA’s Spitzer Space Telescope. Officially named W40, the butterfly is a nebula – a giant cloud of gas and dust in space where new stars may form. The butterflyR
这幅插图描绘了两个小行星大小的天体碰撞的结果：围绕一颗年轻恒星的巨大碎片云。NASA的斯皮策号发现一块碎片云挡住了这颗恒星HD 166191，为科学家提供了发生碰撞的细节。 影像来源：NASA/JPL-Caltech 岩石天体之间的重大碰撞塑造了我们的太阳系。对类似碰撞的观察提供了有关这些事件在其他恒星周围发生频率的线索。 我们太阳系中的大多数岩石行星和卫星，包括地球和月球，都是由太阳系历史早期的大规模碰撞形成或塑造的。通过相互碰撞，岩石天体可以积累更多的物质，增大尺寸，或者它们可以分裂成多个较小的物体。 天文学家使用NASA现已退役的斯皮策太空望远镜，在过去发现了岩石行星正在形成的年轻恒星周
