New Telescope Data Deepens the Mystery of How Fast the Universe Is Expanding
The Atacama Cosmology Telescope’s final polarisation maps reinforce the long-standing Hubble tension, confirming a slower early-universe expansion rate similar to Planck’s findings. By ruling out several proposed fixes, the new data intensifies the mystery and suggests current cosmological models may be missing key physics.

Is the Universe Slowing Down? Astronomers Detect Signs of Fading Dark Energy
Astronomers from Yonsei University and DESI data analyses indicate dark energy, long believed constant, may be weakening. Corrected supernova results hint that cosmic acceleration is slowing—a possible “cosmic slowdown.” If true, this could help resolve the Hubble tension and redefine how the universe’s expansion and ultimate fate are under...

Is Earth In A Giant Cosmic Void? Why New Research Could Change Everything
New research suggests Earth may lie inside a massive, billion-light-year-wide cosmic void, offering a possible solution to the Hubble Tension and changing our understanding of the universes expansion.

Atacama Telescope Reveals Most Detailed Cosmic Microwave Background Yet
New images from the decommissioned Atacama Cosmology Telescope offer the most detailed view of the cosmic microwave background. The data reveals early cosmic structures, tracks primordial gas movement, and refines estimates of the universe’s total mass. While supporting existing models, it does not resolve the Hubble tension. Researchers are now ...

Coma Cluster’s Distance Closer Than Predicted, Amplifying Hubble Tension Crisis
A new study led by Dan Scolnic and Adam Riess reveals that the Coma Cluster is 38 million light-years closer than predicted by standard cosmological models, intensifying the ongoing Hubble tension. This discrepancy, involving measurements of type Ia supernova explosions, challenges the universe's expansion rate as predicted by the Hubble–Lemaîtr...

Study Claims Black Holes Could be Driving Universe's Expansion
A new study proposes that black holes could hold the key to dark energy, which fuels the accelerating expansion of the universe. Using the Dark Energy Spectroscopic Instrument (DESI), astronomers observed a possible correlation between the growth of black holes and an increase in dark energy. The study's co-authors, Gregory Tarlé and Duncan Farrah...

Here's How AI is Helping Astronomers to Understand Universe's Fundamental Parameters
Artificial intelligence is advancing the field of cosmology by enabling astronomers to determine five fundamental cosmological parameters with remarkable precision. Researchers from the Flatiron Institute's Center for Computational Astrophysics (CCA) in New York City have used AI to analyse extensive data from over 100,000 galaxies, observed throug...

James Webb Space Telescope Ends Debate Over the Mysterious ‘Hubble Tension’, Finds Study
Recent analysis of data from the James Webb Space Telescope (JWST) has provided new measurements of the universe's expansion rate, offering fresh insights into the long-standing debate known as the "Hubble tension." For years, astronomers have struggled to reconcile two major methods of measuring the universe's expansion, which have produced differ...

James Webb Space Telescope: First Three Layers of Solar Shield Deployed, Final Two to Be Stretched Today
NASA engineers have begun a crucial phase in deploying the James Webb Space Telescope. The engineers have started to tighten the tension in its tennis court-sized sunshield. The stretching of the first three layers of the five-layer sunshield was successful and the final two layers will be deployed today, January 4
