New research suggests dark matter may interact with neutrinos, which could explain why the universe is less 'clumpy' than expected and challenge current cosmological models. Future observations, including cosmic microwave background studies and gravitational lensing, aim to test this hypothesis, potentially leading to a major breakthrough in understanding dark matter.

A record-breaking gamma-ray burst lasting nearly seven hours was observed, challenging existing models of such cosmic explosions. The event, originating from a dusty galaxy billions of light-years away, involved a high-speed jet of material and may have resulted from various extreme astrophysical processes. This unprecedented observation offers a unique opportunity to study extreme physics in the universe.

Recent studies suggest that dark energy, which is driving the universe's expansion, may be weakening, potentially leading to a reversal of expansion and a possible 'Big Crunch' instead of the previously believed continuous acceleration. This challenges current cosmological models and has sparked significant debate among astronomers.

Researchers from the University of British Columbia explored the potential link between axions, a dark matter candidate, and white dwarf stars, using data from the Hubble Space Telescope. Although their analysis did not find evidence of axion-induced cooling, it established new limits on axion-electron interactions, guiding future dark matter research. The study highlights the importance of exploring various astrophysical phenomena to understand elusive particles like axions.

Most of the universe's normal matter isn't in stars or galaxies but is distributed in the cosmic web between galaxies, with recent studies using fast radio bursts confirming that about 76% of normal matter resides in intergalactic space, supporting the Big Bang theory. Dark matter, which makes up most of the universe's mass, remains largely mysterious, but scientists are actively studying it through various methods including underground detectors and telescopes.
