This Hubble Space Telescope image features two merging galaxies in the VV-689 system, nicknamed the Angel Wing. Unlike chance alignments of galaxies, which only appear to overlap when viewed from our vantage point on Earth, the two galaxies in VV-689 are in the midst of a collision. The galactic int […]
NASA钱德拉X射线天文台对100多个星系进行的一项新调查发现，有迹象表明，黑洞正在吞噬数千颗恒星，以增加其质量。图中所示的4个星系是样本中29个星系中的4个，这些星系显示了黑洞在其中心附近不断生长的证据。来自钱德拉（蓝色）的X射线被叠加在NASA哈勃太空望远镜拍摄的NGC 1385、NGC 1566、NGC 3344和NGC 6503的光学图像上。翻转图中出现的方框勾勒出正在萌芽的黑洞的位置。 这些新的结果表明，至少其中一些黑洞要达到现在的大小，经历了某种程度上暴力的方式——恒星毁灭的规模是前所未见。 天文学家对两类不同的黑洞进行了详细的研究。较小的种类是“恒星质量”黑洞，其质量通常为太阳质
We’re celebrating the Hubble Space Telescope’s 32nd birthday with a stunning look at an unusual close-knit collection of five galaxies, called The Hickson Compact Group 40. This eclectic galaxy grouping includes three spiral-shaped galaxies, an elliptical galaxy, and a lenticular (lens-l
A spectacular head-on collision between two galaxies fueled the unusual triangular-shaped star-birthing frenzy, as captured in this image from the Hubble Space Telescope. The interacting galaxy duo is collectively called Arp 143. The pair contains the glittery, distorted, star-forming spiral galaxy
This striking image from the NASA/ESA Hubble Space Telescope showcases Arp 298, a stunning pair of interacting galaxies. Arp 298 – which comprises the two galaxies NGC 7469 and IC 5283 – lies roughly 200 million light-years from Earth in the constellation Pegasus. The larger of the two galaxies pict
This image from the NASA/ESA Hubble Space Telescope feels incredibly three-dimensional for a piece of deep-space imagery. The image shows Arp 282, an interacting galaxy pair composed of the Seyfert galaxy NGC 169 (bottom) and the galaxy IC 1559 (top). Interestingly, both galaxies have monumentally e

The spiral arms of the galaxy NGC 3318 are lazily draped across this image from the NASA/ESA Hubble Space Telescope. This spiral galaxy lies in the constellation Vela and is roughly 115 million light-years away from Earth. Vela was originally part of a far larger constellation, known as Argo Navis a
在一个相对较小的星系中发现一个超大质量黑洞，有助于天文学家解开最大黑洞如何成长的谜团。 研究人员利用NASA的钱德拉X射线天文台在Mrk 462星系的气体和尘埃中发现了一个黑洞，其质量约为太阳的20万倍。 Mrk 462仅包含数亿颗恒星，是一个矮星系。相比之下，我们的银河系拥有数千亿颗恒星。这是第一次在矮星系中发现被严重掩埋或“遮蔽”的超大质量黑洞。 “Mrk 462 中的这个黑洞是超大质量或怪物黑洞中最小的一个，”新罕布什尔州达特茅斯学院的杰克·帕克说，他与同样来自达特茅斯的同事瑞恩·希科克斯领导了这项研究。 “众所周知，像这样的黑洞很难找到。” 在较大的星系中，天文学家经常通过寻找星系中心
In this image, the NASA/ESA Hubble Space Telescope captures a side-on view of NGC 3568, a barred spiral galaxy roughly 57 million light-years from the Milky Way in the constellation Centaurus. In 2014 the light from a supernova explosion in NGC 3568 reached Earth – a sudden flare of light caused by
