The Eyes Galaxies (NGC 4435-NGC 4438, also known as Arp 120) are a pair of galaxies about 52 million light-years away in the constellation Virgo. The pair are members of the string of galaxies known as Markarian's Chain. NGC 4435 is a …

双眼星系 (NGC 4435-NGC 4438，也称为阿普 120)是一对距离5,200万光年，位于 室女座 的星系。 NGC 4435是一个有短棒的 透镜星系， 史匹哲太空望远镜 发现在它的中心区域有着相对是年轻 (1亿9000万年) 的恒星族群，它们可能起源于与NGC 4438的交互作用。 它也有可能是与上述星系交互作生用所产生的长长的潮汐尾。 NGC 4438是在室女座星系群有交互作用的最奇特星系，由于环境中有不确定的能量机制使核心在加热中；这种能量机制可能是 星暴 区域，或是 活跃星系 …

The galaxy NGC 4438 belongs to the Hubble class SA (s)0/a (peculiar). The inclination of its disk is unclear; values range between 68° and 85° with respect to the sky plane. This galaxy has a distance median value of 13 Mpc.

NGC 4438 is the most curious interacting galaxy in the Virgo Cluster, due to the uncertainty surrounding the energy mechanism that heats the nuclear source; this energy mechanism may be a starburst region, or a black hole-powered active galactic nucleus (AGN). Both hypotheses are currently under investigation by astronomers.

2007年6月21日 · Abstract: We present multi-frequency, radio-continuum and HI observations of NGC4438, the highly-disturbed, active galaxy in the Virgo cluster, with the VLA and the GMRT. High-resolution observations with the VLA at 4860 and 8460 MHz show the presence of an inverted-spectrum radio nucleus located between the highly asymmetric lobes of radio ...

2016年11月16日 · NGC 4435 is a compact barred lenticular galaxy that appears to be almost devoid of dust and gas. The galaxy contains a young population of stars on its central regions.

2000年6月5日 · Known as a peculiar galaxy because of its unusual shape, NGC 4438 is in the Virgo Cluster, 50 million light-years from Earth. Are you a journalist? Subscribe to the ESA/Hubble Media Newsletter.

2003年12月12日 · We present results from a 25 ksec CHANDRA ACIS-S observation of galaxies NGC4438 and NGC4435 in the Virgo Cluster. X-ray emission in NGC4438 is observed in a ~700 pc nuclear region, a 2.3 kpc spherical bulge, and a network of filaments extending 4-10 kpc to the W and SW of the galaxy.

The galaxy NGC 4438 belongs to the Hubble class SA (s)0/a (peculiar). The inclination of its disk is unclear; values range between 68° and 85° with respect to the sky plane. This galaxy has a distance median value of 13 Mpc.

马卡林之链中最突出的是两个相互作用的 星系 ，NGC4438（左）和NGC4435，它们被称为马卡林之眼。 这两个星系距离我们大约5,000万光年远，虽然现在看到的这张高分辨的特写图像上两个星系的距离有10万光年，实际上在更早期它们之间的距离更近，约为16，000光年。 两个星系近距离相遇所产生的引力潮能撕裂星系内的恒星，气体和尘埃。 质量较大的NGC4438星系在这次碰撞中将吸积更多的物质，而NGC4435由于质量较小所以更容易损失物质。 这张引人注目的深空影 …
