Quipu Superstructure: The Largest Known Structure in the Universe

Quipu Superstructure: The Largest Known Structure in the Universe

Introduction

Astronomers have discovered the largest known structure in the universe, named Quipu, an enormous superstructure composed of galaxy clusters and cosmic filaments.

Key Characteristics

Size & Mass:

  • The Quipu superstructure stretches across 1.3 billion light-years.
  • It has a mass of 200 quadrillion solar masses.

Composition:

  • Made up of galaxy clusters, filaments, and voids.
  • It belongs to a class of superstructures, which contain multiple superclusters of galaxies.

Effects of Superstructures

Cosmic Microwave Background (CMB) Disturbances

  • Superstructures like Quipu create fluctuations in the CMB, which is the leftover radiation from the Big Bang.

Impact on the Hubble Constant

  • The presence of massive superstructures distorts accurate measurements of the universe’s expansion rate.
  • This causes variations in the calculation of the Hubble Constant, leading to discrepancies in cosmic models.

Gravitational Lensing (GL) Effects

  • Gravitational lensing occurs when a superstructure bends and distorts light from background galaxies.
  • This phenomenon creates magnified or multiple images of distant objects, helping astronomers study the universe.

Significance of the Discovery

  • Challenges current models of cosmic evolution and large-scale structures.
  • Helps in understanding dark matter and dark energy.
  • Provides insight into the early formation of galaxies.

IN-SPACe CANSAT & Model Rocketry India Student Competition 2024–25: A Giant Leap for Student Innovation

Image
In a remarkable step towards strengthening India’s STEM education framework, the Astronautical Society of India (ASI), in collaboration with the Indian Space Research Organisation (ISRO) and the Indian National Space Promotion and Authorization Center (IN-SPACe), has launched the IN-SPACe CANSAT and Model Rocketry India Student Competition 2024–25 . This unique competition is crafted for undergraduate students across India, providing them with an opportunity to engage in experiential learning through the design, fabrication, and launch of CANSATs—can-sized satellites—using model rocketry platforms. The event held on June 14, 2025 , in Tamkuhi Raj, Kushinagar, Uttar Pradesh , was not a full-fledged rocket launch carrying an actual payload. Instead, it served as a critical site and systems validation test in preparation for the upcoming national student competition. This test focused on ensuring the readiness of launch site infrastructure, safety protocols, telemetry systems, and track...
