Two enormous galaxies capture your attention in this spectacular image taken with the NASA/ESA Hubble Space Telescope using the Wide Field Camera 3 (WFC3). The galaxy on the left is a lenticular galaxy, named 2MASX J03193743+4137580. The side-on spiral galaxy on the right is more simply named UGC 26 […]
This image taken with the NASA/ESA Hubble Space Telescope depicts the open star cluster NGC 330, which lies around 180,000 light-years away inside the Small Magellanic Cloud. The cluster – which is in the constellation Tucana (the Toucan) – contains a multitude of stars, many of which are scattered
This 2004 image was produced by combining a dozen observations from the Chandra X-Ray Observatory made of a 130 light-year region in the center of the Milky Way. The colors represent low (red), medium (green) and high (blue) energy X-rays. Thanks to Chandra’s unique resolving power, astronomer
A cataclysmic cosmic collision takes center stage in this image taken with the NASA/ESA Hubble Space Telescope. The image features the interacting galaxy pair IC 1623, which lies around 275 million light-years away in the constellation Cetus (the Whale). The two galaxies are in the final stages of m
类星体是非常明亮、遥远、活跃的超大质量黑洞，质量是太阳的数百万到数十亿倍。它们通常位于星系的中心，以坠落的物质为食，并释放出奇妙的辐射洪流。类星体是宇宙中最亮的天体之一，类星体的光芒超过了其所在星系中所有恒星的总和，其喷流和风塑造了它所在的星系。 这是一个以明亮的类星体为中心的星系的艺术概念。类星体是一个非常明亮、遥远、活跃的超大质量黑洞，其质量是太阳的数百万到数十亿倍。类星体是宇宙中最亮的天体之一，类星体的光芒超过了其所在星系中所有恒星的总和。类星体以坠落的物质为食，释放出大量的风和辐射，塑造了它们所在的星系。利用韦伯的独特能力，科学家们将研究宇宙中最遥远、最明亮的6个类星体。 影像来源：N
晚上，七岁的米格尔喜欢和他的父亲塞萨尔·卢比奥(Cesar Rubio)谈论行星和恒星。“我试图培养这种能力，”卢比奥说，他是加州波莫纳的一名机械师，为采矿和发电设备制造零部件。 在这张艺术家的渲染图中，两颗气态行星围绕着明亮的恒星HD 152843运行。这些行星是通过公民科学项目行星猎人TESS与专业科学家合作发现的。 图片来源：NASA/Scott Wiessinger 现在，这个男孩可以声称他的父亲也帮助发现了行星。塞萨尔·卢比奥是行星猎人TESS的数千名志愿者之一。行星猎人TESS是一个由NASA资助的公民科学项目，旨在寻找太阳系以外的行星或系外行星的证据。公民科学是公众与科学家合作的
One definition for goulash, according to the Merriam-Webster dictionary, is a mixture of heterogeneous elements, or jumble. This 2017 image of galaxy Arp 299 is just that. Arp 299 is a system located about 140 million light-years from Earth, containing two galaxies that are merging, which has create
Astronomers continue to develop computer simulations to help future observatories better home in on black holes, the most elusive inhabitants of the universe. Though black holes likely exist abundantly in the universe, they are notoriously hard to see. Scientists did not capture the first radio imag
This image shows the spiral galaxy NGC 5037, in the constellation of Virgo. First documented by William Herschel in 1785, the galaxy lies about 150 million light-years away from Earth. Despite this distance, we can see the delicate structures of gas and dust within the galaxy in extraordinary detail
过热的气体和磁场在银河系的中心编织着能量的织锦。这幅新的宇宙杰作的新图像是由美国宇航局钱德拉x射线天文台和南非的MeerKAT射电望远镜的巨大数据拼接而成的。 银河系中心的新全景图是建立在之前钱德拉和其他望远镜的观测基础上的。与以前的成像活动相比，这个最新版本将钱德拉的高能视野扩展到了银河系平面的上方和下方，也就是银河系大多数恒星所在的圆盘。在我们的主图中，来自钱德拉的X射线显示为橙色、绿色、蓝色和紫色，显示不同的X射线能量，而来自MeerKAT的无线电数据则显示为淡紫色和灰色。图片中的主要特征以标注的方式显示。 有一条线特别引人注意，因为它的X射线和无线电发射交织在一起。它垂直于银河系的平面
