Abell 2744, nicknamed Pandora's Cluster, is a giant galaxy cluster resulting from the simultaneous pile-up of at least four separate, smaller galaxy clusters that took place over a span of 350 million years, and is located approximately 4 billion light years from Earth. [1]

2023年2月15日 · Astronomers have revealed the latest deep field image from NASA’s James Webb Space Telescope, featuring never-before-seen details in a region of space known as Pandora’s Cluster (Abell 2744). Webb’s view displays three clusters of galaxies – already massive – coming together to form a megacluster.

2020年9月2日 · This image of the Abell 2744 galaxy cluster combines X-rays from Chandra (diffuse blue emission) with optical light data from Hubble (red, green, and blue). Image credit:X-ray: NASA/CXC; Optical: NASA/STScI. Read feature. Galaxy clusters are the largest objects in the universe held together by gravity.

2011年6月22日 · The giant galaxy cluster Abell 2744, nicknamed Pandora's Cluster, appears to be the result of a simultaneous pile-up of at least four separate, smaller galaxy clusters. The crash took place over a span of 350 million years. The galaxies in the cluster make up less than five...

2014年1月8日 · This long-exposure Hubble Space Telescope image of massive galaxy cluster Abell 2744 (foreground) is the deepest ever made of any cluster of galaxies. It shows some of the faintest and youngest galaxies ever detected in space.

Abell2744 Y1，美国宇航局的斯皮策和哈勃太空望远镜观测到一个极为遥远的星系，将其命名为“Abell2744 Y1”，当时的宇宙只有6.5亿岁。 宇宙当前的年龄为138亿岁。

2018年5月15日 · This long-exposure Hubble Space Telescope image of the massive galaxy cluster Abell 2744 is the deepest ever made of any cluster of galaxies. The observation shows some of the faintest and youngest galaxies ever detected in space.

Abell 2744, also known as Pandora’s Cluster, is a giant pile-up of four smaller galaxy clusters. Abell 2744, and its neighboring parallel field, are among the first targets of the Frontier Fields program. The Abell catalogue of galaxy clusters was first compiled by astronomer George O. Abell in 1958, with over 2,700 galaxy clusters observable…

2019年3月21日 · Abell 2744, nicknamed Pandora's Cluster, is a giant pile-up of four smaller galaxy clusters. The cluster is so massive that its powerful gravity bends the light from galaxies far behind it, making the background objects appear larger and brighter in a phenomenon called gravitational lensing.

One of the most complicated and dramatic collisions between galaxy clusters ever seen is captured in this new composite image. This collision site, known officially as Abell 2744, has been dubbed "Pandora's Cluster" because of the wide variety of different structures seen.
