哈勃望远镜瞥见一对星系二人组

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 2665. Both galaxies lie approximately 350 million light-years ...

哈勃望远镜观测到了一个由红、白、蓝组成的星团

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 across this striking image. Because star clusters form from ...

哈勃影像:猎户座星云

2021年06月29日 Orion Nebula: The Hubble View Image Credit: NASA, ESA, Hubble Legacy Archive; Processing: Francisco Javier Pobes Serrano Explanation: Few cosmic vistas excite the imagination like the Orion Nebula. Also known as M42, the nebula’s glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud only 1,500 light-ye...

哈勃望远镜拍摄的令人眼花缭乱的动态二人组

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 merging, and astronomers expect a powerful inflow of gas to i...

哈勃拍摄到一个迷人的螺旋星系

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. This detail is possible using Hubble’s Wide Field Camera 3...

哈勃太空望远镜追踪到星系旋臂的快速射电爆发

天文学家利用美国宇航局(NASA)的哈勃太空望远镜追踪了五个遥远星系螺旋臂上五次短暂而强大的射电爆发的位置。 这些被称为快速射电风暴(FRBs)的异常事件在千分之一秒内产生的能量相当于太阳一年产生的能量。由于这些短暂的无线电脉冲在眨眼之间就消失了,研究人员很难追踪到它们的来源,更不用说确定是什么或哪些物体造成了它们。因此,大多数时候,天文学家并不知道确切的观测地点。 天文学家利用哈勃太空望远镜追踪到上图中两个星系的旋臂处有两次短暂而强大的射电爆发。左边的两张图片展示了哈勃望远镜拍摄的每个星系的完整快照。右边的两张数字增强图像更详细地展示了每个星系的螺旋结构。这些射电爆发的目录名称是FRB 190714(上排)和FRB 180924(下排)。这些星系远离地球,呈现出数十亿年前的样子。这四幅图像中的每一幅都用虚线标...

哈勃发现宇宙云的银色光芒

This image taken with the NASA/ESA Hubble Space Telescope showcases the emission nebula NGC 2313. Emission nebulae are bright, diffuse clouds of ionized gas that emit their own light. The bright star V565 (center of the image) highlights a silvery, fan-shaped veil of gas and dust, while the right half of this image is obscured by a dense cloud of dust. Nebul...

哈勃凝视着充满宇宙线索的星团

This detailed image features Abell 3827, a galaxy cluster that offers a wealth of exciting possibilities for study. Hubble observed it in order to study dark matter, which is one of the greatest puzzles cosmologists face today. The science team used Hubble’s Advanced Camera for Surveys and Wide Field Camera 3 to complete their observations. The two cameras h...

哈勃望远镜观察巨型行星的成长过程

NASA的哈勃太空望远镜让天文学家们罕见地看到了一颗木星大小、仍在形成中的行星,它正以一颗年轻恒星周围的物质为食。 “我们只是对巨行星如何成长了解不多。”德克萨斯大学奥斯汀分校的布伦丹·鲍勒(Brendan Bowler)说。“这个行星系统为我们提供了第一个见证物质落入行星的机会。我们的结果为这项研究开辟了一个新的领域。“ 这幅新形成的系外行星PDS 70b的插图显示了物质如何随着它的质量增加而落到这个巨型世界上。利用哈勃望远镜的紫外光(UV)灵敏度,研究人员获得了一种独特的观测方法,观察了从极热气体落到该行星上的辐射,使他们首次能够直接测量该行星的质量增长率。PDS 70b行星被它自己的气体和尘埃盘所包围,它从这个行星系中更大的环绕星盘吸收物质。研究人员假设,磁场线从环绕行星的圆盘延伸到该系外行星的大气层,并...

哈勃望远镜观测到一条耀眼的宇宙项链

The interaction of two doomed stars has created this spectacular ring adorned with bright clumps of gas ­– a diamond necklace of cosmic proportions. Fittingly known as the “Necklace Nebula,” this planetary nebula is located 15,000 light-years away from Earth in the small, dim constellation of Sagitta (the Arrow). A pair of tightly orbiting Sun-like stars pro...
