CLJ1001 MOST DISTANT GALAXY- KAVIGNAR THANIGAI.
The galaxy cluster CL J1001 is the most distant galaxy cluster ever seen by any astronomer from Earth. In addition, scientists believe that the galaxy is new born that’s why it was hidden till date from astronomers.

This new galaxy cluster discovered using NASA’s Chandra X-ray observatory has break nearly all records of distance. According to scientists, it is the most distant galaxy cluster they have ever spotted. The galaxy cluster named CL J1001+0220 (or CL J1001 for short) is located nearly 11.1 billion light-years away from Earth.
The cluster contains 11 galaxies and nine of them are witnessing rampant star births. For scientists, it is a remarkable site as not only the galaxy cluster is farthest ever observed but it is giving birth to stars at an unprecedented rate.
Lead researcher Tao Wang from French Alternative Energies and Atomic Energy Commission (CEA) said, “this galaxy cluster isn’t just remarkable for its distance, it’s also going through an amazing growth spurt unlike any we’ve ever seen.”
Apparently, the galaxy cluster CL J1001 is a newly born cluster and is in early stages of evolution said scientists at NASA while explaining about the galaxies. Since the galaxy is located 11.1 billion light years away from Earth, it will help researchers in developing a better understanding of how galaxies evolved in the past.
In addition, galaxies should be tightly packed together to become a galaxy cluster and CL J1001 is one of the best examples of how galaxies get bound together by gravitational forces is early stages of evolution. Scientists are amazed to see how such young galaxies have formed a cluster and they want to study it thoroughly.
Previously, researchers believed that fully grown up galaxies form clusters. Observing this galaxy cluster revealed that more stars form after the cluster is made and galaxies join a cluster when they are isolated and mostly empty.
“We think we’re going to learn a lot about the formation of clusters and the galaxies they contain by studying this object,” said co-author Alexis Finoguenov of the University of Helsinki in Finland, “and we’re going to be searching hard for other examples.”
Moreover, Chandra X-ray Observatory (CXO) is a space observatory launched by NASA on July 23, 1999. It is nearly 100 times more sensitive to X-rays when compared to all other previous detectors. The telescope is named after astrophysicist Subrahmanyan Chandrasekhar. It has a lens that measures 1.2 meter in diameter and the CXO completes one revolution of Earth in 64 hours.
