Oldest Black Hole Discovered Dating Back To 470 Million Years After The Big Bang


In a groundbreaking discovery that has astounded the scientific community, researchers have identified the most ancient black hole ever detected. This celestial behemoth came into existence a mere 470 million years after the birth of the universe during the Big Bang.

The Collaborative Efforts of Webb and Chandra

  • The discovery was made possible through the combined efforts of NASA’s James Webb Space Telescope and the Chandra X-Ray Observatory, which worked in tandem over the past year to unveil this cosmic marvel.

An Ancient Entity in an Expanding Universe

  • Given that the universe is approximately 13.7 billion years old, the age of this black hole is estimated at 13.2 billion years.
  • The newly discovered black hole is an absolute giant, measuring a staggering ten times larger than the black hole residing at the center of our own Milky Way galaxy.

A Weighty Enigma in the Cosmos

  • This ancient black hole is believed to have a mass ranging from 10% to 100% of the combined mass of all the stars within its host galaxy.
  • This mass ratio is incomparable to the minuscule proportions observed in black holes within our Milky Way and nearby galaxies, which typically account for a mere 0.1% of their respective galaxy’s mass.

The Birth of an Ancient Titan

  • Scientists postulate that this prodigious black hole formed from the collapse of massive clouds of gas within a galaxy located adjacent to another galaxy containing stars.
  • These two galaxies eventually merged, with the newly discovered black hole ultimately taking over the central position.

Illuminating the Distant Past: The Gravitational Lensing Technique

  • The collaborative efforts of the Webb and Chandra space telescopes have unveiled an unprecedented view of the universe’s distant past.
  • They employed a technique known as gravitational lensing to magnify the region of space housing the galaxy UHZ1 and its associated black hole.
  • The telescopes harnessed the light emanating from a cluster of galaxies that is relatively closer to Earth, located a mere 3.2 billion light-years away. This amplification effect allowed them to observe UHZ1 and its colossal black hole, situated much farther in the cosmic background.

James Webb Space Telescope

  • The James Webb Space Telescope, launched in 2021 and stationed at a point one million miles from Earth, stands as the most extensive and powerful astronomical observatory ever deployed in space.
  • This cutting-edge instrument observes the universe in the infrared spectrum, enabling the exploration of celestial objects with unmatched precision.
  • Webb’s primary mirror comprises 18 hexagonal mirror segments constructed from beryllium with a gold-plated finish. Collectively, these segments form a mirror with a substantial diameter of 6.5 meters (21 feet), a significant upgrade from Hubble’s 2.4 meters (7 feet 10 inches).

The Remarkable Chandra X-ray Observatory

  • The Chandra X-ray Observatory (CXO), formerly the Advanced X-ray Astrophysics Facility (AXAF), is a flagship space telescope launched by NASA on July 23, 1999, aboard the Space Shuttle Columbia.
  • It boasts extraordinary sensitivity, capable of detecting X-ray sources 100 times fainter than previous telescopes, thanks to its high-angular-resolution mirrors.
  • This telescope is named in honor of the Nobel Prize-winning Indian-American astrophysicist, Subrahmanyan Chandrasekhar.
