NGC 4697 (also known as Caldwell 52) is an elliptical galaxy some 40 to 50 million light-years away in the constellation Virgo.It is a member of the NGC 4697 Group, a group of galaxies also containing NGC 4731 and several generally much smaller galaxies. [3] This group is about 55 million light-years away; it is one of the many Virgo II Groups, which form a …

ngc 4697，也稱為科德韋爾52，是位於室女座，距離在4,000萬至5,000萬光年的一個橢圓星系。 它與ngc 4731和其他幾個小得多的星系都是ngc 4687群的成員 [3] 。 這個群的距離大約是5,500萬光年；它也是形成室女座超星系團南方延伸體，室女座ii群的一員 [3] 。. ngc 4697的距離並沒有很高的精確度：測量的值從 ...

2024年8月23日 · Hubble’s Advanced Camera for Surveys (ACS) image of Caldwell 52 (NGC 4697) appears at the bottom. Hubble also observed the central part of the galaxy with its Wide Field Camera 3 (WFC3). A white rectangle in the ACS image shows the area imaged by WFC3. At top center is an infrared (IR) view of the galaxy’s center.

NGC 4697 is the primary member of the NGC 4697 group of galaxies. This massive elliptical galaxy is slightly larger than the Andromeda galaxy and distorts its neighbors with its gravitational influence.

NGC 4697，也称为科德韦尔52，是位于 室女座，距离在4,000万至5,000万 光年 的一个 椭圆星系。 它与NGC 4731和其他几个小得多的星系都是NGC 4687群的成员。 这个群的距离大约是5,500万光年；它也是形成 室女座超星系团 南方延伸体，室女座II群的一员。 NGC 4697的距离并没有很高的精确度：测量的值从2,800万至7,600万光年。 依据NASA超星系数据库的距离是3,800万光年；依据SIMBAD是5,000万光年。 NGC 4697，也称为科德韦尔52，是位于室女 …

Explanation: The many bright, point-like sources in this Chandra Observatory x-ray image lie within NGC 4697, an elliptical galaxy some 40 million light-years away towards Virgo. Like other normal elliptical galaxies , NGC 4697 is a spherical ensemble of mainly older, fainter, low mass stars, with little star forming gas and dust compared to ...

2023年8月9日 · Caldwell 52 is the most prominent member of a collection of galaxies known as the NGC 4697 Group. Slightly larger than the Andromeda galaxy, this massive elliptical dominates its group, distorting its neighbors with its gravitational influence.

Chandra's image of the elliptical galaxy NGC 4697 reveals diffuse hot gas dotted with many point-like sources. As in the elliptical galaxies, NGC 4649 and NGC 1553, the point-like sources are due to black holes and neutron stars in binary star systems.
