Quipu Superstructure: Astronomers Discover Largest Known Structure in the Universe

 Quipu Superstructure: Astronomers Discover Largest Known Structure in the Universe

Astronomers have identified the largest known structure in the universe, called Quipu.

About the Quipu Superstructure

• This superstructure has a mass of 200 quadrillion solar masses and spans over 1.3 billion light-years.
• Superstructures: These are vast formations containing groups of galaxy clusters and superclusters.

Effects of Superstructures:

• Cosmic Microwave Background (CMB): Superstructures cause fluctuations in the CMB, which is the relic radiation from the Big Bang.
• Hubble Constant: Superstructures can distort accurate measurements of the universe's expansion rate.
• Gravitational Lensing (GL): They can distort sky images due to the bending of light from background sources caused by the superstructure's massive gravitational field.

• The desert lies between the Andes Mountains and the Pacific Ocean.
• Features: It includes salt pans, alluvial fans, dunes, and volcanic cones.
• Climate & Environment: It is one of the driest places on Earth.
