Hubble Catches Galaxies Swarmed by Star Clusters

In a core of a abounding cluster of galaxies located in a instruction of a constellation of Coma Berenices, lies a universe surrounded by a overflow of star clusters. NGC 4874 is a hulk elliptical galaxy, about 10 times incomparable than a Milky Way, during a core of a Coma Galaxy Cluster. With a clever gravitational pull, it is means to reason onto some-more than 30,000 globular clusters of stars, some-more than any other universe that we know of, and even has a few dwarf galaxies in a grasp.

In this NASA/ESA Hubble Space Telescope image, NGC 4874 is a brightest object, located to a right of a support and seen as a splendid star-like core surrounded by a misty halo. A few of a other galaxies of a cluster are also visible, looking like drifting saucers dancing around NGC 4874. But a unequivocally conspicuous underline of this design is a point-like objects around NGC 4874, suggested on a closer look: roughly all of them are clusters of stars that go to a galaxy. Each of these globular star clusters contains many hundreds of thousands of stars.

Recently, astronomers detected that a few of these point-like objects are not star clusters though ultra-compact dwarf galaxies, also underneath a gravitational change of NGC 4874. Being usually about 200 light-years opposite and mostly done adult of aged stars, these galaxies resemble brighter and incomparable versions of globular clusters. They are suspicion to be a cores of tiny elliptical galaxies that, due to a aroused interactions with other galaxies in a cluster, mislaid their gas and surrounding stars.

This Hubble design also shows many some-more apart galaxies that do not go to a cluster, seen as tiny smudges in a background. While a galaxies in a Coma Cluster are located about 350 million light-years away, these other objects are most over out. Their light took several hundred million to billions of years to strech us.

This design was combined from visual and near-infrared exposures taken with a Wide Field Channel of Hubble’s Advanced Camera for Surveys. The margin of perspective is 3.3 arcminutes across.
