A cluster of galaxies is shown with many galaxies around the cluster center. A close look at this center shows that it is encompassed by a narrow ring of light. Please see the explanation for more detailed information.
图中显示的是一团星系，许多星系围绕着星系团的中心。仔细观察星系中心，可以发现它被一圈狭窄的光环所包围。有关更多详细信息，请参阅说明。
2022年7月5日 A Molten Galaxy Einstein Ring Image Credit: ESA/Hubble & NASA, S. Jha; Processing: Jonathan Lodge Explanation: It is difficult to hide a galaxy behind a cluster of galaxies. The closer cluster’s gravity will act like a huge lens, pulling images of the distant galaxy around the sides and greatly distorting them. This is just the case observed in the featured image recently re-processed image from the Hubble Space Telescope. The cluster GAL-CLUS-022058c is composed of many galaxies and is lensing the image of a yellow-red background galaxy into arcs seen around the image center. Dubbed a molten Einstein ring for its unusual shape, four images of the same background galaxy have been identified. Typically, a foreground galaxy cluster can only create such smooth arcs…
