A study of the gravitational lensing of this system suggests that the light emitted has been magnified by a factor of ~10. It is still substantially more luminous than nearby quasars such as 3C 273. Quasars were much more common in the early universe than they are today.
UHZ1 is a background galaxy containing a quasar. At a redshift of approximately 10.1, UHZ1 is at a distance of 13.2 billion light-years, seen when our universe was about 3 percent of its current age. [1] [2] This redshift made it the most distant, and therefore earliest known quasar in the observable universe as of 2023.
Any quasar with z > 1 is receding faster than c, while z exactly equal to 1 indicates recession at the speed of light. [33] Early attempts to explain superluminal quasars resulted in convoluted explanations with a limit of z = 2.326, or in the extreme z < 2.4. [34] The majority of quasars lie between z = 2 and z = 5.
In 2011, a large quasar group was discovered, U1.11, measuring about 2.5 billion light-years across. On January 11, 2013, another large quasar group, the Huge-LQG , was discovered, which was measured to be four billion light-years across, the largest known structure in the universe at that time.

This list includes superclusters, galaxy filaments and large quasar groups (LQGs). The structures are listed based on their longest dimension. This list refers only to coupling of matter with defined limits, and not the coupling of matter in general (such as, for example, the cosmic microwave background, which fills the entire universe).

It began as a brush fire near the site where an earlier fire, called the Lachman Fire, had been located on Jan. 1, and it spiraled out of control as high winds hit the region.
